    NoClassDefFoundError using Eclipse/JUnit

    Neill Laney Newbie

      hello, I'm accessing a WS running on JBoss 4.2.2 using JBossWS 2.0.3

      I've generated the service artifacts using wsconsume and I'm getting a NoClassDefFoundError running the client code as a JUnit or Java app.

      The same test runs OK from the command line using wsrunclient, or at least when copying the generated cmd line string into a cmd prompt, and it works when running the test during the Maven build lifecycle.

      I would like to be able to run the tests in the Eclipse WTP 2.0 workbench. Any help would be appreciated. The test is just a basic HelloWorld, and the stacktrace is:

          A bit of additional information, the classpath for the JUnit run configuration are set the same as the command line classpath.

          TIA, if anyone is able to help with this problem!

            Neill Laney Newbie

            Problem: wsclientrun sets the classpath in the command line and runs OK. Run/Debug/Junit threw NoClassDefFoundError with the stacktrace in the previous post. The classpath was set on the classpath tab.

            Solution: use the same command line arguments as wsclientrun in the JVM arguments field of the arguments tab to set the classpath.

            Note: it was necessary to copy the output of wsclientrun and make some changes to the classpath argument, to include bin;output which are the class folders for the test class and the wsconsume generated classes.

            Run/Debug/Junit all run without errors!
