I have been able to have a WSRP portlet react to local events via JBoss Portal IPC. Note that IPC was not part of WSRP 1.0, nor Portlet 1.0 (JSR 168) so it had to be addressed in a proprietary way by portal vendors. JSR 286 (Portlet 2.0) and WSRP 2.0 offer a standard way to deal with IPC but at this time are not fully integrated in JBoss Portal (JSR 286 will be supported in JBoss Portal 2.7, WSRP 2.0 will follow sometime later). May I ask what your use case is? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136775#...
