Inter-portlet communication

I'm analyzing the approach to developing a portal in websphere 6. The implementation is going to require that communication take place between portlets that exist on separate pages. Documentation I'm coming across seems to explicitly note that it's inter-portlet communication for the same page.
Is the portlet communication going to be different when they're on a separate page? Won't that still work with websphere's property broker.

thanks for any information and/or links

Indeed, if you are using JSR168 portlets, there really is no messaging infrastructure. The best you can do is place information in an application_scope session. But that only works for portlets in the same portlet application. If your portlets are not packaged together in the same war, even the application_scope of the session won't work for you.

IBM has C2A, or click-to-action, which they've invested alot of effort into. This indeed allows for communication between portlets across multiple pages.

Here's a tutorial on how to use C2A to do just that:

Happy Portal!
