IPC between two JSR 168 portlets with out reloading the page(asynchronoes)

My requirement is IPC between two JSR 168 portlets with out reloading the page(Lleft and right portlets)


I made asynchronoes desktop and I used the custom events

I fired the left portlet event from the right portlet in the below way it worked perfectly.

Event in left portlet :
---------------------

public void getMessage(ActionRequest request, ActionResponse response,

Event event) {

CustomEvent customEvent = (CustomEvent) event;

String message = (String) customEvent.getPayload();

response.setRenderParameter("message0", message);

}

Add/Create event handelar "messageCustomEvent" from from properties file in left portlet

I called the left portlet event from the right portlet processAction method in the below way

javax.servlet.http.HttpServletRequest httpRequest = (javax.servlet.http.HttpServletRequest)request.getAttribute("javax.servlet.request");

com.bea.netuix.servlets.controls.portlet.backing.PortletBackingContext context = com.bea.netuix.servlets.controls.portlet.backing.PortletBackingContext.getPortletBackingContext(httpRequest);

context.fireCustomEvent("messageCustomEvent", navvar);


It worked perfectly with out refereshing the screen
