Well I figured out the problem was that in the header the Soap action has to be in quotes and currently the soap client doen't put the Soap Action in quotes, I fixed it, recompiled the 4.2.1 ESB and it is working. I have created a JIRA Feature request with the code and the Jbossesb-soap.jar The link to that is as follows http://jira.jboss.com/jira/browse/JBESB-1397 With out the quotes the response is an Error, as the web service cannot get the web method. I hope to see this in the next issue View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111285#...
