Hi, where in your MBean is this code snippet located? In the constructor or in some MBean lifecycle method? I suggest that you try to extract your MBean to a new project and strip it off all code besides the "new InitialContext();" call. This should work. If you know that it works, you know that there is another problem with your project (maybe some old class bundled). It it does not work either, you can repost it here. Hope this helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4236327#...
