I think I've figured out what I was doing to create this problem. Here's what I was attempting to do during the test: On the machine that produces the remote portlet, I created another instance of the CurrentUsersPortlet and attempted to consume it from my test machine. This produced the errors that I posted here earlier. I realized today, that it is not necessary to create another instance; instead I should just consume the one that is already there. Also, I installed the latest release 2.6.4, to ensure that today's testing will have all of the latest fixes. Now everything appears to be working much better. It was just a momentary lapse of reason on my part :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129699#...
