Proceeding as previously (Hello World exercise), you are asked to define a web service that calculates the square and the double of a number and the sum multiplication, and the division of two intgers.

The service returns this time a number. The method to be invoked has a parameter.

To process methods with parameters, suppose your service has the computeSquare method with the following signature:

    public class SquareDouble{
            public int computeSquare (int nb) {
                      return nb * nb;
            }
 
            // fininsh the other operations
  }
 

Assuming that your service is called SquareWorldService, the invocation will then be carried out as follows:

   http://localhost:8080/axis2/services/SquareWorldService/computeSquare?args0=10

You will get the following response (still in SOAP XML format), here is an excerpt:

 <soapenv: Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance ">
   <soapenv: Body>
     <calculateResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
       <calculateReturn xsi:type="xsd:int"> 100 </calculeReturn>
     </calculeResponse>
   </soapenv:Body>
 </soapenv:Envelope>

Develop a java client as before (Hello World exercise) or Servlet which gives the square, the double, the addition, multiplication, sous traction and division of integers.
