Ate,
I've built the latest portals-bridges-struts-1.2.7-0.4-SNAPSHOT.jar and
deployed it in my webapp.
I'm using Eclipse to step through the code. This is my Execute method :-
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
logger = Logger.getLogger("Cedar-Portlets");
logger.debug("SetURLAction::execute - starting");
try {
ActionRequest actionRequest = (ActionRequest) request
.getAttribute(ContainerConstants.PORTLET_REQUEST);
String id = this.getInstanceID(actionRequest);
String msg_session_id = MessageHelper.getSessionID(actionRequest);
MessageHelper.loadPrefs(actionRequest, id, msg_session_id);
MessageHelper msgh = new MessageHelper(actionRequest
.getPortletSession(true), id, msg_session_id);
msgh.send("a_val",
"this is a message from SetURLAction in portlet webapp "
+ actionRequest.getContextPath());
} catch (RuntimeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return mapping.findForward("failure");
}
return mapping.findForward("success");
}
actionRequest is always coming back as null, if I take a look at the attributes
that are set within the HttpServletRequest, the only ones I can see being set
are :-
org.apache.struts.action.MESSAGE
org.apache.struts.action.mapping.instance
org.apache.struts.action.MODULE
no sign of javax.portlet.request.
This is driving me round the bend !!!!!
Any further assistance would be greatly appreciated, examples or otherwise.
Jonathan

Subject: Re: Struts Bridge and Inter Portlet Communication
Thanks Ate,
I was getting null pointer exceptions. I'll subscribe to the other list as
well andbuild the struts bridge and see what I can get hold of this time.
I've created my own constants file with an entry for javax.portlet.request.
All assistance is very much appreciated.
