Hi Anton or other experts out there, This morning, I finally can switch back to jboss. I tried to deploy your example (similar to the first MDB example in the manual, see attached zip), but got the identical error messages as before when I tried the example in the manual and in the test. I checked the manual, the error message "communication exception" is "the exception that represents any error that can't readily be ascribed to a definite cause", so, we do not have any luch there. And, "java.net.MalformedURLException" sometimes means there are spaces in the installation path (something C: \program Files) but I installed it as C:\jboss. here is the whole server "dos" output after I started the server. Note that the stateless session "Interest" example works fine (search <== to get the most interesting/problematic part) thanks in advance!!
