I have a 4.2.1.GA with jbossws-2.0.1.GA installed. I ran undeploy-jboss42 in the 2.0.1.GA installation directory. Then I ran deploy-jboss421 in the jbossws-2.0.2.GA installation directory. Tried to start jboss and got lots of ClassNotFound errors. After hunting around a bit, I see that in macros-deploy-native.xml the macro-deploy-native421 definition contains this. <copy todir="${jboss421.home}/server/${jboss.server.instance}/lib" overwrite="true"> | <fileset dir="@{thirdpartylibs}"> | <include name="jbossws-jboss421.jar"/> | </fileset> | </copy> But there is no jbossws-jboss421.jar jar in the 2.0.2.GA installation zip. I dropped in the jbossws-jboss42.jar from the 2.0.2.GA installation into server/default/lib and also client/lib. This deploys without errors and runs all the 2.0.2 test cases. Are there any known incompatibilities with this jar and the new jbossws version? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4109077#...
