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! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127241#...
