Java2WSDL error - Attempted to write duplicate schema element

[Sanjay Dahiya]

Hi
I ran Java2WSDL in a simple Java class to gnerate a doc/literal WSDL and 
got exception, it doesnt say what to fix to get the wsdl right, google 
also didnt help. same worked fine for RPC/enc and REPC/lit WSDL.

public class HelloWorld{
       public String getMsg1(String str){
               return "Hello World ! " + str ;
       }
       public String getMsg2(String str, int i){
               return "Hello World ! " + str ;
       }
       public String getMsg3(String[] i){
               return "Hello World ! array "  ;
       }
       public String getMsg3(HelloWorld i){
               return "Hello World ! array "  ;
       }
}
# ../java2wsdl.sh HelloWorld -l http://localhost:8080/axis/helloworld -o 
helloworld.wsdl --style DOCUMENT --use LITERAL -n http://test/helloworld
