The GWT maven plugin should have no influence on the seam dependency, as that's a server side dependency and the GWT maven plugin only compiles the client javascript files. Actually, I don't think maven is involved whatsoever: having the WebSession class twice in the classpath would just make the JVM hide the second one and the app wouln't be able to detect to it or crash on it. Looks like tracing down the bug should start in components.xml imho: With kind regards, Geoffrey De Smet (at devoxx all week) Op 14-11-10 12:48, Nicolas Héron schreef: > Hello, > I am trying to build (and work) on guvnor > so I check out the source code and the normal mvn command > and when deploying on jboss-4.2.2.GA <http://jboss-4.2.2.GA> > here is the error,it seams seam is declared twice.
