It is essential to have a backend framework to make an application with which end-users can communicate and perform some actions. The front-end experience depends on the backend, including business logic, user request processing, database interactions, and performance. Most companies are reaping the benefits of robust back-end frameworks to deliver a high-quality application with an excellent user experience.
Given the prominence of backend frameworks of 2024, there is no surprise that you need to choose the best backend framework from a broad range of options out there.
When dealing with front-end development, we all begin with the browser and its benefits. However, backend development is a mystical field. The backend programs execute the functions of your sites with a database, which runs on your server. According to YouTube’s analysis and data visualization project, “Statistics & Data,” in 2024, Laravel has 76,304 repository stars from users and Django has 76,109 and Flask is third with 66,999.

3. 1 introDUction – Why open stAnDArDs?
Today, there is a wide array of technologies and tools available to software developers that can
be used to develop web based applications. When selecting products and tools to build and
support their IT systems, enterprises need to rely on a proven foundation to be assured that their
applications can be built in accordance with good architectural principles and goals.
Technologies built upon open standards typically encompass good architectural traits as they,
by definition, need to promote interoperability. Building applications upon open standards
provides a level of insurance to enterprises that means they need not be locked into a specific
vendor’s product and that the investment in an application need not be lost should the enterprise
decide to change some part of their infrastructure (e.g. an application server or database server).
In order to achieve the maximum benefit of developing applications to open standards, some
design discipline must be applied. For a decade or more, building applications using a layered
architecture has become a ubiquitous principle, because it encourages a clear separation of
responsibility between the components in an application, such as locating business logic in
a dedicated layer and not spread throughout the application. This approach is beneficial in
decoupling the core of an application from the User Interface (UI) and data storage technologies
used by the application. This, in turn, makes the application more flexible to change than would
otherwise be possible, which is a key trait for enterprise applications.
Best practice now recommends that application developers should use standards-based
interfaces, because this both increases the portability of an application and lowers the cost of
maintenance through the availability of developers with more generalised skills. A common
example of where this discipline is not applied is where enterprises put most of their business
logic into stored procedures rather than application code. This makes both maintenance (scaling
the application becomes expensive because application servers are cheaper than database
servers, per CPU) and portability (because stored procedures are always proprietary) more
costly than necessary. On occasion it may make sense for specific application functions to use
proprietary features of a particular product (e.g. where there is a definite performance benefit),
but such instances should be the exception rather than the rule.
In recent times enterprises have come to realise the benefits that Open Source software can offer.
Widely used Open Source products, such as Red Hat Enterprise Linux and Ingres, have allayed
prejudices about reliability and security flaws which might have resulted from the Open Source
development model. Best of breed products that are developed under an Open Source license
can be every bit as reliable, secure and scalable as their commercial counterparts.
Developing Applications Using open source technology :: 3
4. 1.1 Advantages of an integrated stack
As with the commercial software market there is a bewildering choice of competing products in
the Open Source software market. Deciding on a combination of Open Source products that can
be used to form an enterprise-capable software stack can be a formidable task and not without
risk, for example how can enterprises know that the selected products will work well when
combined? In answer to this problem, some Open Source product vendors partner to offer a
complete application platform that is already integrated and tested, thus reducing this risk.
When enterprises select an application platform that is based on pre-integrated Open
Source software, they gain the benefits of enhanced productivity and predictability. Open
Source products have frequently been used by enterprises during the development of
their applications - even if the application will eventually run on commercial products in
a different production environment - because this reduces some of the drain of software
license costs. With enterprises looking to lower the overall cost of their IT systems, the up-
front license costs associated with commercial software products are one source of cost that
offers no business benefit for an enterprise, as additional fees still need to be paid to receive
support from the product vendor. For this reason, many enterprises are today looking to
replace commercial products with Open Source alternatives for production use as well as in
development.
In addition to these cost related arguments, Open Source software has also proven itself in
terms of supportability, security, resilience, performance, high availability and other attributes
needed to qualify as being enterprise class. This means that it is now being used much more
frequently as the basis of true enterprise class application infrastructure.
Using a pre-integrated software stack in this scenario delivers productivity gains partly
because developers and system administrators need to spend less time installing and
configuring disparate products, and partly because using the same products from
development through production reduces the effort associated with testing and configuring
the application for the different environments. By using a supported stack, enterprises looking
to replace their software infrastructure with Open Source software will see the additional
benefit of predictability. Using the same application platform in development, pre-production
and production environments reduces the possibility of differences between the application
server and database products introducing unforeseen problems.
This white paper is a short tutorial that outlines how to set up and develop a simple layered
application using the JBoss open source application technology platform based on the Java
Enterprise Edition platform (JEE), and using the Ingres RDBMS for persistent data storage.
This tutorial application will run on JBoss middleware and make use of the JBoss Seam
framework.
Both Ingres and JBoss middleware are used by enterprises in mission and business critical
applications so can be considered as mature and proven technologies and consequently a good
foundation upon which applications can be developed and run in production environments.
Developing Applications Using open source technology ::
5. 1.2 background to products Used Within the stack
The JBoss Server project has been active since 1999. Over that time JBoss Application Server
(JBoss AS) has become the most widely used Java Enterprise server, and has moved with
the times with the objective of supporting the most current JEE specifications. At the time
of publication the most current version of JBoss AS is 5.0, which complies with the JEE 5
specifications.
The Ingres RDBMS dates back to the inception of relational database technology. Based on
code originally developed as part of a research project at University of California, Berkeley, the
database product continued to be developed as a commercial entity until it was open sourced
by Computer Associates in 2004. Over its lifetime, the core database has maintained a strong
adherence to industry standards such as SQL and provides a wide range of connectivity options
including JDBC, ODBC, Python, Perl, PHP and Ruby.
The JBoss Seam framework is comparatively new, and primarily exists to enhance the JEE
programming model by providing additional features to support more complex use cases that
can arise with fully featured Rich Internet Applications (RIA). The Seam framework integrates
AJAX, Java Server Faces (JSF), Facelets, Enterprise Java Beans, Java Persistence API (JPA),
Java Portlets and Business Process Management to provide a fully featured web development
framework.
Seam builds upon core JEE technologies but incorporates additional technologies to offer a
unified programming model and more flexibility targeted at web applications. Seam treats
JSF as a first class citizen and enhances the JSF approach to provide useful features not yet
covered by the JSF specification. Additional features include contextual state management,
support for RESTful URLs, an enhanced exception handling mechanism and a convention
over configuration approach that alleviates most of the burden associated with creating and
maintaining XML configuration files.
2 prereqUisites
The practical elements of the tutorial assume the reader has basic experience of the following:
• Developing Java applications with Eclipse and the Web Tools plugin
• Familiarity with JEE, primarily web components (JSF, Servlets, JSP), EJB and JPA entities and
JEE deployment modules
• Familiarity with Facelets
The following software components are used in the tutorial - please refer to the Resources
section for information on downloading the software:
• Java Development Kit (1.5 or above)
• Ingres RDBMS 9.2.0
• JBoss AS 5.0.0 GA
Developing Applications Using open source technology ::
6. • JBoss Seam 2.1.0 SP1
• Eclipse Ganymede JEE Build
• JBoss Tools 3 CR1 (an Eclipse plugin)
It is suggested that the software be installed in the order presented in the list above, however
with the exception of the JBoss Tools Eclipse plugin which requires that Eclipse is installed and
running, there is no strict order in which the software must be installed. The Eclipse IDE comes
bundled with an embedded Java Runtime so the IDE will run without an external Java Runtime
or Development Kit. Note that the last four components are also packaged together within the
commercially available JBoss Developer Studio.
Source code for the domain entity classes and a pre-built EAR module with the complete
example application, along with deployment instructions, can be found at:

3 tUtoriAl
This section includes a step-by-step guide to creating a skeleton Seam application using the
Eclipse IDE which can serve as a starting point for developing a fully featured web application.
The application allows a user to view and edit products and orders via list and detail web
pages.
The home page is a simple default page that outlines features offered by Seam. The hyperlinks
at the top of the page are used to navigate to the screens we will create.

8. 3.1 system Architecture
The following diagram outlines the core architectural components of a Seam application. A
subset of the components will be used for the sample application (the components coloured
blue).
The role of each architectural component can be described as:
• Facelets – Assembles the JSF UI components to form the view to be presented in response to a
client request;
• JSF – Provides the UI components used to construct the user interface;
• Seam – The Seam framework provides functionality that can straddle each layer of the
application. A primary function of Seam is the management of requests from the client
(browser), directing requests to an appropriate controller and ensuring that the controller is
in an appropriate state to service a request (e.g. component dependencies are satisfied). The
dependency and state management functionality provided by Seam should be viewed as an
infrastructure function as these features might be used in other layers of the application;
• Hibernate – Manages the ORM mapping layer, allowing the application to use an object
interface and interact with the database;
• JBoss AS – The application server is an infrastructure component that provides services
to hosted applications. The application server is a host for the Seam application providing
additional services such as transaction management and security;
• Ingres – Persistent storage of the application data.
Developing Applications Using open source technology ::
9. 3.2 create the database
The first step is to create the database to be used for the tutorial. The database is to be called
seamapp.
Database creation on Ingres can be achieved in one of two ways, using either the Visual DBA
tool or the createdb utility.
If using Visual DBA, connect to the server by selecting the database server in the Nodes explorer
and using the Node - Connect menu. This will display the object browser for the database
server. Right-click the ‘Databases’ node in the database objects browser. Complete the relevant
details in the wizard and click OK.
If using the createdb command-line utility, the following command is used to create the
database:
createdb seamapp
Developing Applications Using open source technology ::
10. 3.3 register the database with the eclipse Data source explorer
The Eclipse Data Tools plugin provides the capability to explore and interact with JDBC compli-
ant databases from within the IDE. It provides a subset of features offered by the Ingres Visual
DBA tool but with the convenience of being able to access these directly within the IDE.
The Ingres JDBC driver must be registered with Eclipse to allow the Data Source Explorer to
display the database. This can be done prior to registering the database as outlined in Appendix
B of this document but can also be done at the same time a new Connection Profile is created.
The following steps assume that the Ingres JDBC driver is already registered.
Ensuring that the ‘Data Source Explorer’ view is currently visible, right click the Databases node
and select the ‘New…’ option to create a new Connection profile.
Select Generic JDBC from the list and change the name to something suitable such as ‘Ingres
DB’. Progress through the wizard and complete the details as appropriate. The user login details
required are those of an operating system user with Ingres access permissions, on the machine
hosting the database server, and by default you should enter the details of the user who installed
Ingres. The connection can be tested using the ‘Test Connection’ button available on the second
page of the wizard.
The Data Source Explorer can be used to examine database table structures and any data
contained within the tables.
Developing Applications Using open source technology :: 10
11. 3. create a new seam project
The Seam Web Project wizard, included with the JBoss Tools plugin, is to be used to create the
skeleton application structure. An alternative approach would be to use the ‘seam-gen utility’
that is included as part of the Seam installation.
First ensure that the Seam Perspective is enabled. This can be done via the Window - Open
Perspective - Other dialog and selecting Seam from the listing. With the Seam perspective
enabled, the Seam Web Project wizard can be accessed from the File - New menu.
The application will be named ‘seamexample’. Complete the wizard details as required, being
sure to provide a name for the project and that the selected ‘Configuration’ option is a ‘Dynamic
Web Project with Seam 2.0’. The default choices should be acceptable provided a JBoss runtime
and server have been previously configured as outlined in Appendix B.
Proceed through the next two wizard pages, accepting the default options.
Proceed to the final page of the wizard and complete the remaining details. For the General
options, select the Seam runtime (note that the CR release of the JBoss Tools plugin did
not recognise a previously installed instance so a new one had to be created). Complete the
remaining details enabling the ‘EAR deploy’ option, and for the database options select the
Connection profile created earlier.

12. At this point it is worth reviewing what has been created by the project generation wizard.
Seam JBoss
Projects Tools Palette
Seam JBoss
Components Server View
Developing Applications Using open source technology :: 12
13. Firstly examining what can be seen in the Package Explorer view.
The Seam Web Project wizard has created 4 separate Eclipse projects artefacts.
• The seamexample project is created as a WTP Dynamic Web Project configured to include the
Seam facet. Building this project will create a WAR archive. Components that will be included
in this project include the Facelets view templates and Seam configuration files.
• The seamexample-ejb project is created as a WTP EJB project. Building the project will create
a Jar file. Components that will be included in this project include Session EJBs and any JPA
Entities.
• The seamexample-test project is a standard Java project that will include all of the TestNG test
cases.
• The seamexample-ear has created a WTP EAR archive project that will build the JEE
enterprise archive to be deployed to the server. The Ear archive will include the build artefacts
from the Web and EJB projects.
3. seam perspective features
With the Seam perspective enabled it should be possible to see a couple of design aids provided
by the JBoss Tools plugin, as highlighted on the screenshot above.
3.5.1 JBoss Tools Palette
This view is a palette of UI components that can be used during the design of the JSF UI. JBoss
Tools provides a visual designer for building JSF UIs, where the palette components can be
dragged onto a form designer to build up the UI.
3.5.2 JBoss Server View
This view is an extension of the WTP plugin’s Server view. It facilitates control of server
instances registered with the IDE and provides the capability to:
• Start and stop the server;
• Start the server in debug mode;
• Change the startup configuration for the server, and;
• View applications deployed in the server.
The JBoss Server view allows the server configuration file (jboss-service.xml) to be edited from
within the IDE.
3.5.3 Seam Components
This view displays the contents of the components.xml file included in any Seam projects,
supporting the visual editing of this file.
As will be shown in the next section, the Seam perspective offers handy wizards for creatingnew
Seam artefacts to be included in the application. When non-Seam components are required,
switching to the Java EE perspective can be useful to get access to context sensitive content
creation wizards, for example EJB creation wizards for EJB projects or Servlet or Filter creation
wizards for Web projects. Otherwise, these wizards can be accessed using the ‘Other’ option that
should be visible from the ‘New’ context menu.
Developing Applications Using open source technology :: 13
14. 3. creating seam components
It is now time to create the components for the application. Like ‘seam-gen’, JBoss Tools provides
the ability to generate most of the artefacts needed for a simple data maintenance function.
Artefacts can be generated from a set of existing JPA entities or an existing database schema.
The tutorial will focus on using the first approach, of first creating the application domain
model, annotating the model classes and then using JBoss Tools to generate the UI templates
from the domain classes. The code generation is a one-off process so it is better to spend some
time getting the domain model as near as possible to what will be required for the application.
The domain model to be used is detailed by the following UML class diagram.
The database Entity-Relationship model is detailed in the following diagram.
The process to be used to create the entity classes for the application will be:
• Create a new Java class for the entity
• Add JPA annotations
• Add Hibernate Validator annotations
Developing Applications Using open source technology :: 1
15. The full source code for the domain classes can be found in the appendix. In the following
section, code snippets are included to highlight the use of JPA and Hibernate Validator
annotations.
3.6.1 Creating the Entity classes
Create a new class using the Eclipse class wizard. Note that the CR version of the JBoss Tools
wizard did not create the empty com.ingres.seamexample.entity package, so this can be either
be created prior to the creation of the new class or can be created by the New Java Class wizard
providing the package field is first populated with the package name.
If the package exists, right-clicking against the package in the ‘Package Explorer’ view and
selecting New-Class will initialise the New Java Class wizard with the current package
information.
Create new classes for the Item, Order and OrderLine entities and also for an OrderLineId class,
which is not contained within the UML class model but which will be used as the OrderLine
identifier and will contain the compound primary key values that form the OrderLine primary
key. Note that the classes should also implement the java.io.Serializable interface.
3.6.2 Adding JPA / Hibernate Validator Annotations
In this section annotated code fragments from the entity classes will be included with a
description of the annotations that have been added to create the Object-Relational Mapping
(ORM) and data validation constraints.
Developing Applications Using open source technology :: 1
16. First up is the Address class. This, in fact, is not modelled as an entity class at all, but instead it
has been mapped as value type that will be associated with an Order entity.
@Embeddable
public class Address implements Serializable {
private static final long serialVersionUID = 1L;
@Column(name = “address_line1”, length = 40)
@NotEmpty
private String line1;
@Column(name=”address_line2”, length = 40)
private String line2;
@Column(length = 30)
@NotEmpty
private String city;
@Column(length = 30)
@NotEmpty
private String country;
@Column(length = 9)
@NotEmpty
@Pattern(regex = “[A-Z]{1,2}[0-9]{1,2}? [0-9]{1,2}[A-Z]{1,2}”)
private String postcode;
… get/set methods
}
The Address class is marked with an @Embeddable annotation. Embeddable classes are
sometimes referred to as component or value types because the values for an Address object are
to be persisted but the object does not have a unique identity within the system.
The Item class is presented next.
@Entity
public class Item implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Integer code;
@Column(name = “manufacturer_code”, length = 20)
private String manufacturerCode;
@Column(length = 50)
@NotEmpty
@Length(max = 50)
private String description;
@Version
private Timestamp version;
… get/set methods
}
Developing Applications Using open source technology :: 1
17. The @Entity annotation marks this as a persisted object that requires a unique identifier within
the system.
The @Id annotation marks this field as the identifying property of the entity. The @
GeneratedValue annotation specifies that the identity value is to be provided by some other
component the first time the entity is persisted. JPA supports a number of key generation
strategies, and sticking with the default generation strategy (GeneratorType.AUTO) will result in
the default generation type specified by the dialect for the target database. In the case of Ingres,
sequences will be used as the generation mechanism.
The @Column annotation specifies the field mapping between properties of the class and
columns of the related database table, which will default to be named ‘item’ (as no @Table
annotation to override the default table name mapping has been included). The @Column
annotation allows various aspects of the column mapping to be specified (e.g. column length,
nullability) and these become relevant when the database schema is created from the mapping
metadata.
The @NotEmpty is a Hibernate Validator feature that specifies the property value can be neither
null nor an empty value.
The @Length annotation is a Hibernate Validator feature that can be used to specify minimum
and maximum length of a String.
The @Pattern annotation is a Hibernate Validator feature that in this instance uses an example
regular expression to validate the postal code according to UK rules (provided just as an
example).
The @Version annotation specifies that an optimistic locking strategy is to be used to control
concurrent updates of the entity. The mapped property is typically an integer number or
timestamp.
The code for the Order class is next.
Developing Applications Using open source technology :: 1
18. @Entity
public class Order implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
private Integer reference;
@Column(name=”created_date”)
@Temporal(TemporalType.DATE)
@NotNull
private Date createdDate;
@Embedded
@NotNull
private Address deliveryAddress;
@OneToMany(mappedBy = “order”, cascade = CascadeType.REMOVE)
private CollectionOrderLine orderLines;
@Version
private Timestamp version;
public Order() {
this.setDeliveryAddress(new Address());
this.setOrderLines(new ArrayListOrderLine());
}
… get/set methods
}
The Order class contains a number of new annotations.
The @Temporal annotation is used to specify the mapping of a date and time value. The range
of possible values originates from the TemporalType enumeration and can be a date, time or
timestamp value.
The @NotNull annotation is a Hibernate Validator feature that requires the property to have a
value.
The @Embedded annotation is used to identify the class as a value type whose mapped fields are
to be persisted as part of the entity so in this case the mapped fields from the address object will
be persisted within the order table.
The @OneToMany is a collection type mapping, linking an Order to many OrderLine instances.
The ‘mappedBy’ attribute identifies the property on the OrderLine class that this entity is
mapped to and the ‘cascade’ attribute specifies what is to happen to the child dependency when
the Order entity is modified.
The OrderLine class has been modelled as an Association Class. The association between Order
and Item could have potentially been mapped as a bi-directional many-to-many association but
as the association includes additional attributes (e.g. quantity) then a separate entity is preferred.
Developing Applications Using open source technology :: 1
19. @Entity
@Table(name = “order_line”)
public class OrderLine implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
@NotNull
private OrderLineId id;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = “item_code”,
nullable = false,
insertable = false,
updatable = false)
@NotNull
private Item item;
@Column(nullable = false)
@Min(1)
private int quantity;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = “order_reference”,
nullable = false,
insertable = false,
updatable = false)
private Order order;
@Version
private Timestamp version;
… get/set methods
}
The @Table annotation illustrates how to override the default table name mapping.
Use of the @EmbeddedId annotation is described further on.
The @ManyToOne identifies the property as the many end of a many-to-one association. The
identity value could be inferred from the associated property type but the database mapping
has been altered to use more intuitive column names for the database table. The @JoinColumn
annotation is used to describe the mapping. Setting the nullable, insertable and updatable
attributes to false ensures the entity cannot be directly persisted to the database but must first be
associated with valid Order and Item entities before it may be persisted.
The @Min annotation is a Hibernate Validator feature used to ensure the quantity ordered for a
specific item is one or more.
A composite identifier is required for the OrderLine entity, so the @EmbeddedId is used to
specify a separate class is to be used as the entity identifier. In the case of the OrderLine class
the identity value is derived from the associated Item code and Order reference values. This is
represented in the database by the order_line table requiring a compound primary key mapping
based on foreign key references to records in the order and item tables. There are a couple of
Developing Applications Using open source technology :: 1
20. ways to specify a compound key mapping with JPA, but in this case a separate class OrderLineId
(the code for which is provided below) has been created to model the identity. The class is
marked as @Embeddable and must adequately override the equals and hashCode methods from
the java.lang.Object class.
@Embeddable
public class OrderLineId implements Serializable {
private static final long serialVersionUID = 1L;
@Column(name = “order_reference”, nullable = false)
private Integer orderReference;
@Column(name = “item_code”, nullable = false)
private Integer itemCode;
… get/set methods
}
This completes the creation of the domain model. As a general point it should be remembered
that where possible good object-oriented design principles such as encapsulation should be
followed as closely as possible. It is a good practice to only expose as much of the entity class
as necessary to client code, for example, the version property is only of interest to the ORM
tool and should never be set directly by front-end code so this property should use the most
restrictive access level which in the case of JPA is the protected access level. Similarly, if the
ORM tool is exclusively responsible for assigning new entity identities then make the mutator
(set) method as restrictive as possible.
3.6.3 Generate the Seam artefacts
The code generation features provided by the ‘seam-gen’ utility and JBoss Tools are a great way
to quickly produce a prototype for an application. The code generation procedure will use the
JPA mapping and Hibernate Validator annotations present in the entity classes to influence the
generation process. For example, JPA Collection type associations will be displayed as tabular
entries in the page of the parent entity and front-end validation constraints will be derived from
the validation annotations.
To generate Seam artefacts using JBoss Tools, start the ‘Seam Generate Entities’ wizard.
Assuming the Seam perspective is enabled, this can be displayed by selecting the Seam project
in the Package Explorer view, right-click to display the New menu and select the Seam Generate
Entities option.
Developing Applications Using open source technology :: 20
21. In the resulting wizard, select ‘Use existing entities’ and click Finish, leaving the remaining
options at their defaults. As the Seam project was configured to be an EAR project, JBoss Tools
will expect the entity classes to be located in the seamexample-ejb project.
At this point it is worth examining the artefacts produced by the code generation process.
In the seamexample-ejb project, look in the com.ingres.seamexample.service package. The
package will contain a Home and List class for each entity. These extend classes provided by the
Seam Application Framework to provide data maintenance (CRUD) capabilities for the entities.
The accompanying UI artefacts will be located in the WebContent directory of the seamexample
project. The generation process will have created Edit and List Facelets view templates (.xhtml
files) for each entity class and also a Seam pages.xml file which can be used to define fine-
grained rules to dictate the flow between pages. A menu entry will also have been added to the
WebContent/layout/menu.xhtml template.
3.6.4 Verify the generated code
The generated code will only serve as a starting point for an application. It is probable that the
code will need to be checked and possibly modified to get the application behaving as required.
For example, the generated pages may need amending to display fields in a preferred order or
layout, and the generated classes will need to be checked for compilation errors that may occur if
the class or property names result in conflicts.
Developing Applications Using open source technology :: 21
22. In the case of the domain model used in the tutorial some code modifications will be necessary.
The OrderLineHome and OrderLineList classes in the com.ingres.seamexample.service package
will need to be modified, because the generated classes include a call to OrderLine’s setId
method and the OrderLine class restricts access to this method so this results in a compilation
failure. As the default constructor of the OrderLine class ensures that the id property is
instantiated, the assignment of an empty id value by the OrderLineHome and OrderLineList
classes is redundant and so should be removed.
The use of Order as a class name causes a conflict in the OrderList class with the inherited
getOrder method of EntityQuery (which is a Seam Application Framework class). The getOrder
method in OrderList needs to be renamed to something else (e.g. getOrderInstance) to resolve
the conflict. Any action bindings in the generated UI templates (OrderList.xhtml) will also need
to be updated to call the renamed method.
Developing Applications Using open source technology :: 22
23. 3. running the application
The JBoss Tools plugin will deploy the EAR module to the JBoss server identified during the
project creation step. The server can be started in the JBoss Server View by selecting the server
instance and using the context menu options or the icons at the top right-hand side of the view.
Once the application server has started the home page for the application can be accessed using
the URL:
http://localhost:8080/seamexample

24. 3. summary
This tutorial has demonstrated that with appropriate technology choices and tools, it is possible
to undertake rapid application development without sacrificing important enterprise features
that ensure that mission critical applications can run reliably, securely and scale to meet user
demand.
The Seam framework is a fully featured web application framework that is an Open Source
product that builds upon open standards. This allows the application to be deployed to any
number of JEE application servers, either lightweight containers such as Tomcat or fully
fledged application servers like JBoss that offer distributed transaction management, messaging
capabilities and clustering features for fault-tolerance and scalability. The abstraction offered by
JPA on JDBC prevents lock-in to a specific persistent storage mechanism, allowing the database
server to be swapped for another JPA capable solution with little or no code changes, hence
delivering the benefit of avoiding vendor lock-in at both application server and database levels.
