Many web applications require the same sequence of steps to execute in different contexts. Often these sequences are merely components of a larger task the user is trying to accomplish. Such a reusable sequence is called a flow. Consider a typical shopping cart application. User registration, login, and cart checkout are all examples of flows that can be invoked from several places in this type of application. Spring Web Flow is the module of Spring for implementing flows. The Web Flow engine plugs into the Spring Web MVC platform and provides declarative flow definition language. This reference guide shows you how to use and extend Spring Web Flow. This guide covers all aspects of Spring Web Flow. It covers implementing flows in end-user applications and working with the feature set. It also covers extending the framework and the overall architectural model. Java 1.4 or higher Spring 2.5.4 or higher Professional from-the-source support on Spring Web Flow is available from SpringSource, the company behind Spring, and Ervacon, operated by Web Flow project co-founder Erwin Vervaet You can help make Web Flow best serve the needs of the Spring community by interacting with developers at the Spring Community Forums. Report bugs and influence the Web Flow project roadmap using the Spring Issue Tracker. Subscribe to the Spring Community Portal for the latest Spring news and announcements. Visit the Web Flow Project Home for more resources on the project. Each jar in the Web Flow distribution is available in the SpringSource Enterprise Bundle Repository. These jars may be accessed using Maven or Ivy dependency managers. To access jars using Maven, add the following repositories to your Maven pom: com.springsource.repository.bundles.release SpringSource Enterprise Bundle Repository - SpringSource Releases http://repository.springsource.com/maven/bundles/release com.springsource.repository.bundles.external SpringSource Enterprise Bundle Repository - External Releases http://repository.springsource.com/maven/bundles/external ]]> Then declare the following dependencies: org.springframework.webflow org.springframework.binding 2.0.6.RELEASE org.springframework.webflow org.springframework.js 2.0.6.RELEASE org.springframework.webflow org.springframework.webflow 2.0.6.RELEASE ]]> And if using JavaServerFaces: org.springframework.webflow org.springframework.faces 2.0.6.RELEASE ]]> To access jars using Ivy, add the following repositories to your Ivy config: ]]> Then declare the following dependencies: runtime" /> ]]> And if using JavaServerFaces: runtime" /> ]]> Each jar in the Web Flow distribution is also available in the Maven Central Repository.
