...
Step 1 - Create your flow definition xml
...
...
Step 2 - Configure Spring's applicationContext.xml
...
...
The Struts2FlowAdapter allows a Struts 2 action to execute a webflow action-state. The Struts2FlowAdapter uses the id of the action state as the name of Struts 2 action to execute. The alwaysRedirectOnPause is disabled because whether to redirect or not is easier to control in the Struts 2 configuration files.
Step 3 - Add SWF interceptors to Struts's struts.xml configuration file
...
...
The SessionFlowExecKeyInterceptor puts the flow execution key in the session rather than having it as a hidden field on the form that submitted back. The AnnotationFlowScopeInterceptor uses annotations to bind Struts 2 action variables to and from flow scope. Before an action executes, this interceptor looks for @FlowIn annotated properties of the Struts 2 action and populates the these actions from flow scope. After the action has executed, properties annotated with the @FlowOut annotation are put back into flow scope.
Step 4 - Configure the FlowAction so Spring Webflows can be executed
...
For each view-state defined in the flow xml definition, there should be a corresponding result entry in the FlowAction definition. (Or a global result for that view-state)
...
The flow can now be launched by accessing the FlowAction.
