I hope you use adb as the axis2 client. Here the problem seems to be the receiving message is not compatible with the wsdl file you have used to generate the code. So please get the request you receive and validate it against the wsdl file and see. If it vaild please send it so that I'll have a look. What is the axis2 version you use?
