SPRING WEB FLOW 2.0.5 (November 2008)
----------------------------------
http://www.springframework.org/webflow

1. INTRODUCTION
---------------
Spring Web Flow (SWF) is the module of Spring that allows you to implement the "flows" of your web application.

A flow is an application module that encapsulates a sequences of steps that can execute in different contexts.
Flows typically guide a single user through the execution of some business task.
They often execute across HTTP requests, have state, exhibit transactional characteristics, are reused, and may be dynamic and long-running in nature.
Good examples of flows include a trip booking process, a loan application process, and an insurance quoter.

Spring Web Flow exists at a higher level of abstraction, providing you a declarative flow definition language for authoring flows.
Web Flow also integrates as a self-contained flow engine within base web frameworks such as Spring MVC.
It allows different UI technologies to be integrated, including UI component technologies such as JavaServerFaces.

Spring Web Flow lets you capture reusable application UI flow in a declarative, portable, and manageable fashion.
It is a powerful controller engine that addresses the "C" in MVC.

4. GETTING STARTED
------------------
This distribution contains documentation and sample applications demonstrating the features of the Spring Web Flow projects.
A great way to get started is to review and run the sample applications, supplementing with reference manual material as you go.
To build deployable .war files for all samples, simply access the projects/build-spring-webflow directory and run ant.
All projects are directly importable into Eclipse as "Dynamic Web Projects".
See http://www.springframework.org/webflow-samples for more information.

5. OBTAINING RELEASE JARS FROM THE SPRINGSOURCE BUNDLE REPOSITORY
-----------------------------------------------------------------
Each jar in the Web Flow distribution is available in the SpringSource release repository.
These jars may be accessed using Maven or Ivy dependency managers.
Browse the contents of the repository by accessing http://www.springsource.com/repository.

To access jars using Maven, add the following repositories to your Maven pom:

<repository>
    <id>com.springsource.repository.bundles.release</id>
    <name>SpringSource Enterprise Bundle Repository - SpringSource Releases</name>
    <url>http://repository.springsource.com/maven/bundles/release</url>
</repository>

<repository>
    <id>com.springsource.repository.bundles.external</id>
    <name>SpringSource Enterprise Bundle Repository - External Releases</name>
    <url>http://repository.springsource.com/maven/bundles/external</url>
</repository>

Then declare the following dependencies:

<dependency>
    <groupId>org.springframework.webflow</groupId>
    <artifactId>org.springframework.binding</artifactId>
    <version>2.0.5.RELEASE</version>
</dependency> 

<dependency>
    <groupId>org.springframework.webflow</groupId>
    <artifactId>org.springframework.js</artifactId>
    <version>2.0.5.RELEASE</version>
</dependency> 

<dependency>
    <groupId>org.springframework.webflow</groupId>
    <artifactId>org.springframework.webflow</artifactId>
    <version>2.0.5.RELEASE</version>
</dependency> 

If using JavaServerFaces:

<dependency>
    <groupId>org.springframework.webflow</groupId>
    <artifactId>org.springframework.faces</artifactId>
    <version>2.0.5.RELEASE</version>
</dependency> 

To access jars using Ivy, add the following repositories to your Ivy config:

<url name="com.springsource.repository.bundles.release">
    <ivy pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
    <artifact pattern="http://repository.springsource.com/ivy/bundles/release/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
</url>

<url name="com.springsource.repository.bundles.external">
    <ivy pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
    <artifact pattern="http://repository.springsource.com/ivy/bundles/external/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
</url>

Then declare the following dependencies in your ivy.xml:

<dependency org="org.springframework.webflow" name="org.springframework.binding" rev="2.0.5.RELEASE" conf="compile->runtime" />
<dependency org="org.springframework.webflow" name="org.springframework.js" rev="2.0.5.RELEASE" conf="compile->runtime" />
<dependency org="org.springframework.webflow" name="org.springframework.webflow" rev="2.0.5.RELEASE" conf="compile->runtime" />

If using JavaServerFaces:

<dependency org="org.springframework.webflow" name="org.springframework.faces" rev="2.0.5.RELEASE" conf="compile->runtime" />
