Hi Prabhat, Thanks for the reply! My java version is 1.6.0_02. My portal version is 2.6.6.GA. I cannot seem to find any documentation about whether this configuration should work or not. Is Java 6 and JBoss Portal 2.6.6.GA incompatible? I will chase up the JMS stuff elsewhere. I am sure that portal deployed into a clean JBoss would work, however I am trying to get an understanding of the stack and would like to figure out how to get rid of these errors if I can. Cheers, Troy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4176001#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
