Hello,

I have a webservice which is being accessed by WebMethods.My service is in Jboss-4.0.3SP1.
My service method is as follows
public OrderResponse orderRequest(orderrequestheaderType orderrequestheader, IteminfoType iteminfo) throws
java.rmi.RemoteException;
As can be seen this method accepts two parameters.But when WM tries to access my webserice the following is thrown.
