SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encodi... means an rpc/encoded wsdl, that is no longer supported since it has been disallowed in WS-I basic profile. The @SOAPBinding(style = SOAPBinding.Style.RPC) annotation says you want a rpc style wsdl (rpc/literal). I would verify that the vbs environment you're using support rpc/literal or document/literal wsdls. Btw you can expose custom wsdl documents with jbossws, but of course they have to be compliant with standards.
