In Axis2, no WSDD is required. POJO is what I am using. At the server, users just need to write OO program as usual. No particular work is required. I notice that the sample, addressbook, in the directory of POJO accompanied with AXIS binary package, works fine. My case should be the same as that. But the method on the server is not recognized for my method's parameters is changed from String to Ljava/lang/java!
What I am wondering why Ljava/lang/java comes out? I never use it. I believe a proper design of Web services development system should NOT bother users with so many underlying techniques.
