IPC and PortalEventListener

[analyzediz]

Hi all --

I've read through the JBoss Reference documentation and portlet spec and I have a fundamental design question. On this forum, I've seen a combination of approaches for performing IPC. These approaches consist of using PortalEventListener (defined in the jboss-service.xml), defining coordination parameters within the *-object.xml file and at times, calling the setEvent() method during the processEvent() method of the portlet.

My use case dictates that there are two portlets on a page. When a user clicks on a link in one portlet, it will initiate a search in another portlet. The link that is clicked contains the query parameters (search keywords). There could be upwards of 10 or more of these query parameters. Should I be entertaining public render parameters or should I use events here.

If I go with events, then which of the combination of approaches mentioned above would be ideal.

I'm using JBoss 2.7.0 CR1 [Bundled].

I would deeply appreciate it if any pointers could be provided.

Thank you so much!

You should go with events, you could create a serializable object to store all those params. And use that object for the event.

Thanks so much for your suggestion.

I'll give that approach a try.
