IPC with JSR 168 portlets and WebLogic Portal 9.2.3

Question

I have seen examples in this forum indicating that you can implement IPC in JSR 168 portlets by doing the following:
1. Fire a custom event in the processAction() method of one portlet.
2. Handle the custom event in another portlet that is listening for the event.
3. The listening portlet should contain a method such as
processMyCustomEvent(ActionRequest req, ActionResponse resp, Event event)4. The method is mapped as a handler for the custom event in the listening portlet's +.portlet+ file:
<netuix:javaPortlet definitionLabel="jsr168EventPortlet" title="JSR168 event portlet">
   <netuix:handleCustomEvent event="myCustomEvent" eventLabel="customEventOne" filterable="true" description="custom event handler">
      <netuix:invokeJavaPortletMethod  method="processMyCustomEvent" />
   </netuix:handleCustomEvent>
</netuix:javaPortlet>However, the examples I've found in this forum seem to pertain only to installations of WebLogic Portal 10.x or higher.
Does this JSR 168 IPC approach work for WebLogic Portal 9.2.3?
(The example provided in the WL Portal 9.2.3 documentation uses a Backing File to handle the event instead of invoking a method in the portlet class itself.)
Any clarification that can be provided would be much appreciated. Thanks.

Hello,
Yes, JSR168 portlet IPC is supported in WLP 9.2, and you can use the "invokeJavaPortletMethod" (recommended) or the invokeBackingFileMethod in the .portlet file to configure your portlet to receive events.
