WebWork comes with a utility called WebFlow. WebFlow is used to generate graphical diagrams representing the flow of your web application. It does this by parsing your configuration files, action classes, and view (JSP, Velocity, and FreeMarker) files. An example of a typical output of WebFlow is provided (for the full size, click here):

Additional information can be found in the JavaDocs:

Setting up

WebFlow is built in to WebWork, so if you're up and running with WebWork, you don't need to do anything additional java packages. However, WebFlow does require the "dot" package by GraphViz.

...

java -cp ... -jar webwork.jar
     -config CONFIG_DIR 
     -views VIEWS_DIRS 
     -output OUTPUT 
     [-ns NAMESPACE]

Where:

• CONFIG_DIR is the directory where xwork.xml and other configuration files are located
• VIEWS_DIRS is a comma separated list of directories where you JSPs and Velocity files are located
• OUTPUT is the directory where WebFlow will write its files
• NAMESPACE (optional) is the namespace that you wish to restrict WebFlow

Some advanced users may wish to execute WebFlow from within their application – this could be required if you are developing an application that supports WebWork plugin capabilities. This can easily be done.
