I am trying to deploy an ear build with Eclipse WST on a JBoss 4.2.0.RC1 server (but actually I have the same problem on a JBoss 4.0.5), using JBoss IDE 2.0 beta2 and Eclipse 3.2.1. The REPUBLISH of the ear doesn't work on a JBoss Inc configured server (but the removal work properly). The point is that with a 4.0.5, I can use the generic JBoss server provided by WST, but this configuration doesn't work with JBoss 4.2.0.RC1 due to some changes in the libraries deployed librairies, so I have no choice than use the Jboss Inc. server configuration. This problem was already reported in this post with no response : http://www.jboss.com/index.html?module=bb&op=viewtopic&t=98858 Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4025708#...
