Hello Prabhat, I obtained that problem when trying myfaces portlet, not JSFRI one. Anyway, I have two questions: 1. When using JSFRI portlet, that library should be in the WEB-INF of the portlet or in the server? 2. Do I need to have portletbridge in order to work with any of the technologies (JSFRI or myfaces)? Thank you again. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143810#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
