Hi! Thanks for your reply, yes im using eclipse version 3.4.2 to build. In my Java Build Path i have inluded the jbossws-client-3.0.1-native-2.0.4.GA.jar under the Library folder In my Run|Run Configuration the classpath contains the same jar under the User Entries, WSTestServiceClient project (default classpath) Is there something missing or is there somewhere else I need to setup? Also when i debug the row Eclipse throws the followig error Thread.dispatchUncaughtException(Throwable)line: not available And I get a view with the text Source not found. And a button "Edit Source Lookup path" I tried to recconect the Jar file and put it in a simpler path (c:/temp) but without success. Thank you in advance on any tip or pointers.
