Is it Math.ear or math.ear Try deleting the ear and create again. I once had similar problem and when I rebuilt everything was fine. Also you could do this @Stateless(name="com.azavia.Math") in your bean access using math/com.azavia.Math/remote This is what happened to my ejb. First I could not access using the way you are doing.. But when I gave a name, it was all fine. Then later, I switched back to first way, it worked. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3986789#...
