21 <p>After reading the following explanation about this Struts Interop/Merge
22 example, please click the Continue link near the bottom of the page.
23
24 <p>This example demonstrates the complete interoperability between page flows
25 and Struts. The strutsInteropController page flow instantiates a form bean,
26 JpfFormBean, then passes this form to the Struts module: strutsModule. </p>
27
28 <p>The Struts module will then alter the contents of the form and pass it back
29 to the page flow. Because page flow forms derive from Struts forms, this
30 sharing of the form bean is possible.</p>
31
32 <p>Page flows by default scope form bean instances to the request. But because
33 in this example we want to pass the form bean from the page flow to the struts
34 module, strutsModule, we must scope the form bean to the session. We do this
35 by using the "struts-merge" attribute on the "@jpf:controller" annotation in
36 the strutsInteropController.jpf source file. This attribute will cause the
37 contents of the specified Struts XML file to be merged-in with the generated
38 jpf-struts-config-strutsInterop.xml file. In the event of a naming conflict, artifacts in
39 the Struts "merge" file always takes precedence.</p>
40
41 <p>The form bean we use in this example has a single field, "field1". At each step
42 the action (whether page flow or Struts) will update the value of "field1" so you an see
43 that the same instance of the form is being passed around.</p>
44
45 <p>Also note that the Jsp1.jsp (this JSP) and Jsp3.jsp pages are part of the
46 page flow, while Jsp2.jsp is associated with the Struts module. </p>
