Understanding the Output

There are several key things to notice when looking at the output from WebFlow:

• Boxes: those shaded red indicate an action; those shaded green indicate a view file (JSP, etc).
• Links: arrows colored green imply that no new HTTP request is being made; black arrows indicate a new HTTP request.
• Link labels: labels may sometimes contain additional useful information. For example, a label of href means that the link behavior is that of a hyper-text reference. The complete label behaviors are provided:
  • href - a view file references an action by name (typically ending with the extension ".action")
  • action - a view file makes a call to the Action Tag
  • form - a view file is linked to an action using the Form Tag
  • redirect - an action is redirecting to another view or action
  • ! notation - a link to an action overrides the method to invoke

Requirements

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.
