Java EE (Java Enterprise Edition) General Discussion

Hi
I have simple .net webservice which adds 2 numbers (int). I am trying to invoke it from a axis client using a small java code. It returns me the output as 0 for ints and null if i try to work with strings.

I am not sure if this is because of datatype mismatch or for some other reason. It gives no error messages. This is the code below:

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import org.apache.axis.utils.Options;
import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import java.net.URL;

public class InvokeClient1 {

public static void main(String [] args)
{
try {

String endPoint = "http://localhost/WSTest/AddTest.asmx?WSDL";

Service service = new Service();
Call call = (Call) service.createCall();
call.setProperty(call.SOAPACTION_USE_PROPERTY, new Boolean(true));
call.setProperty(call.SOAPACTION_URI_PROPERTY, "http://localhost/WSTest/AddTest.asmx/AddNumbers");
call.setTargetEndpointAddress( new java.net.URL(endPoint));
call.setOperation( "AddNumbers" );

Integer i1 = new Integer(2);
Integer i2 = new Integer(3);

call.addParameter("arg0",XMLType.XSD_INT, ParameterMode.IN);
call.addParameter("arg1",XMLType.XSD_INT, ParameterMode.IN);
call.setReturnType(XMLType.XSD_INT);

Integer ret = (Integer) call.invoke( new Object [] { i1, i2 });
System.out.println("result: " + ret);
} catch (Exception e) {
e.printStackTrace();
}
}
}

Please help
Regards
