I have a web service client which I use to post a simple Echo message with JBOSS 4.2.2 GA and JBOSSWS-Native-3.0.3 stack. I see a SOAPException due to unsupported content type: application/xml. Could I be missing libraries on the client side which could fix this error and generate the right content type?
Client libraries depends on enabled features like ws-security etc.
It is easier to see the problem if you post client and server code snippets along with stack traces for both.
