problem with publish in Eclipse....
hi~!
I'm trying to develop small Ejb app using using jboss recently.
Eclipse 3.1.2
jboss 4.0.5
Ejb 2.0
The App is working well right after starting the jboss and modifying App
and publish it once in eclipse.
However the problem( Exception below) happens when I publish App twice
and more. And if I restart the server, it works well but publishing more
than twice it throw the same Exception.
I'm very new to start develope Ejb in jboss so I'm not sure whether it
caused by jboss setting or IDE.
Could anyone save me from this error?
