The Struts2FlowAdapter allows a struts2 Struts 2 action to execute a webflow action-state. The Struts2FlowAdapter uses the id of the action state as the name of struts2 Struts 2 action to execute. The alwaysRedirectOnPause is disabled because whether to redirect or not is easier to control in the struts2 Struts 2 configuration files.

Step 3 - Add SWF interceptors to

...

Struts's struts.xml configuration file

<interceptors>
	<interceptor name="sessionFlowExecKey" class="com.googlecode.struts2webflow.SessionFlowExecKeyInterceptor"/>
	<interceptor name="annotationflowScope" class="com.googlecode.struts2webflow.annotations.AnnotationFlowScopeInterceptor"/>
</interceptors>

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 struts2 Struts 2 action variables to and from flow scope. Before an action executes, this interceptor looks for @FlowIn annotated properties of the struts2 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.
