"jboss.ws:<ws mbean>" is an invalid internal URI for the SOAPProxy. You need to replace "<ws mbean>" with the actual mbean name of the web service, which you can find out by navigating the JMX Console.
You can find an example of a proper internal URI for the SOAPProxy in the Programmer's Guide, the SOAPProxy javadoc, and in any of the webservice proxy quickstarts, for example: webservice_proxy_basic.
Of course, now I'm thinking you probably replaced the actual name with "<ws mbean>" just for the purpose of this forum post - LOL...
I'm probably not going to be much help unless I can have a test case, or at least your pertinent configuration files as-is. (jboss-esb.xml, deployment.xml, etc.)
Precisely LOL. Anyway, I took a look at the example and figured it out.
Just for the record I was missing this Barrier MBean. Just adapted the wsbarrier-service.xml file to from the webservice_proxy_basic example my own pourpose.
Precisely LOL. ..
Hahaha... it's been one of those days. I'm glad you got it workin'.
