Dear Martin, I appreciate so much for your help!
However, I am still confused about the problem. I tried one example as follows. In this example, a String is sent as a parameter. And then a local method, getAddr(String keyword), of an object, MyAddress, is invoked. I noticed that it worked fine. My case should be the same as that. What I am wondering why such a type Ljava/lang/String emerged! I never touched that. Moreover, even though I changed the String to String[], the problem still exists. Really don't understand why Web services has such a design. I use POJO to implement my Web services. Could you give me a hand?
