I didn't solve the problem(InterOperability within Client and Server Application) yet . I attach the Client-side VB-file and Server-side java-service-class file used Testing. First, i deployed the DeployDescriptor.xml file using Apache Tool-kit. It's difficult to call the method from Client-side(VB) and return the value. Could you correct this file at your earliest convenience? Thanks a lot.
