I will try to explain : 1 I have generated a web service client with the jaxws maven plugin 2 I have tested it with a JUnit test : it's ok 3 I have created a process and have used the same code as the unit test in an ExternalActivityBehaviour in order to consume the web service 4 I have packaged the process in a *bar file* and deployed it with an ant build file. The bar file contains the jpdl  files, the ExternalActivityBehaviour class and all jaxws generated classes. 5 When the process starts and enter in the custom node, I obtain "*Cannot load service endpoint interface*" because "*ClassNotFoundException*" (the generated client interface in fact) If I have understood, the classloader (the same used by the SOAP stack) can't find the classes of my bar file. I read some posts that say : with jbpm3 we have to add java source files in the process archive. So I have tested and packaged a new bar file with the .java files near .class files, but same result. So my question is : *How to consume a web service from an ExternalActivityBehaviour with the generated client classes all packaged in a bar file*. I have no war file, just a bar file to deploy. I hope I haven't to put all generated classes in a jar and in a jboss lib directory. Thanks in advance.
