Thank you for the clarification. I am glad to know that we can use remote portlet as this is very important for our next release. For the jboss-xml-binding.jar, I don't see any documentation of installing it. In the server, there is one in ${JBOSS_HOME}/client, but there are none in ${JBOSS_HOME}/server/${SERVER}/lib. I copied the one from client directory to the server lib, but I got the same error. I also copied the one from the source "thirdparty/jbossas/core-libs/lib" to both client and server/lib. I got the same error as well. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964113#...
