Dear all,

I am sorry for the previous email that I sent accidentally before finishing my email...

I am trying to implement a simple test service by using Axis2. I have generated service codes and service archive(.aar file) using eclipse plugin successfully. I have 2 methods in my service class..

1- public int addNum(int i, int j){
       System.out.println("I am in addNum");
       return i+j;
}

2- public String getUserInfo(String id){
    System.out.println(id);
.......
    return aResult;
}

I have 2 questions..My question is I am getting weird exceptions...

My first question is; When I a make a service call for "addNum" I am getting an exception as below (It is like can not find service method addNum since it is not printing out the System.out.println thing):

2- My first question is; When I a make a service call for "getUserInfo" method, I can successfully call the service but the problem is my System.out.println(id); print ""..So it can call the service but the parameter id comes as empty string.

Please help if you have any idea...I really do appreciate any suggesstions.

Thank you in advance.
