I'm still fighting with this java.lang.NullPointerException: MEP not found problem. The only difference I have with other WSDL documents is the soap binding type is RPC.
The WSDL file is valid, I changed every part, every namespace, and still I'm getting the same error. I even checked the JbiInInterceptor source code. As I see MEP is calculated from message if SOAPAction="". Simply I don't see the reason for this NullPointerException ... Zsolt
