Axis 2 WebService : wrong number of arguments when invoking method

I'm trying to set up a webservice using axis2. I've created a Dynamic Web Projet under Eclipse, using Apache Tomcat 7 and the dynamic web version 2.5. I've added the Axis 2 Facets to the configuration.

I have the following class : 

package com.jo.ws;

public class Test {
    public int add(int a, int b) {
        return a + b;
    }
}

I then created a WebService for the projet, using the Bottom up Java bean Web Service, and adding my Test class to the service implementation. I chose the "Start Service" in the slider, and changed Apache Axis in the configuration to Axis 2. I then generated a default services.xml file using the default option.

I can access my projet on the web at the following adress :

http://localhost:8888/Axis2WS/

This displays the Axis 2 page, and I can see my service is active

 http://localhost:8888/Axis2WS/services/listServices

The wsdl is correctly generated and displayed

I can post it if needed.

But now if I do this : 

http://localhost:8888/Axis2WS/services/Test?method=add&a=2&b=1

I get this :

<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
<soapenv:Text xml:lang="en-US">wrong number of arguments</soapenv:Text>
</soapenv:Reason>

I also got the error in my Eclipse console log, with the following stack trace : 

[ERROR] wrong number of arguments

Any idea what I'm doing wrong ?

Thanks for your help !

The error came from the url I was typing in the browser.. The right url to invoke the method is :

http://localhost:8888/Axis2WS/services/Test/add?a=3&b=2

You need to replace the "?" with a "/" before the name of the method, and then write your parameters after you've added a "?" after the name of your method
