Hi, Today I upgraded to Jboss 4.2.0 GA Application server. But when I tried to compile the sample example for Jboss ESB , webservice_jbossws_adapter_01, but I was unable to compile as it uses java 5 Annotation. I struggled a lot for 3 hours that, this particular example compiles well in jboss 4.0.5 GA AS but it fails in Jboss 4.2.0 GA AS. I found that if we put the jar file jsr181-api , this example compiles well. In the earlier Jboss 4.0.5 GA AS , it refers to the following two jar files. jboss-remoting.jar,jbossws-client.jar Please check it, if possible.
