Hi, I think that your bpel process is deployed properly, maybe the error is in the test client. First, look if your bpel process is deployed in the server like a web service, it should be in this link http://localhost:8080/jbossws/services. If is there, you can test it like a web service with any web service client. In the wiki, there is an user guide with an example to test the process with Visual Basic. http://wiki.jboss.org/wiki/Wiki.jsp?page=JbpmBpelDesigner Look at the end of the guide, the point 36.
