下面的是　JAVA调用
Integer i = new Integer(1);
Integer j = new Integer(2);
String endpoint="http://localhost/WebService/ApplicationService.asmx";
Service service = new Service();
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint));
call.setOperationName("IntAdd");
call.addParameter("a",XMLType.XSD_INT,ParameterMode.IN);
call.addParameter("b",XMLType.XSD_INT,ParameterMode.IN);
call.setReturnType(XMLType.XSD_INT);
call.setUseSOAPAction(true);
call.setSOAPActionURI("http://localhost/IntAdd");
Integer k = (Integer)call.invoke(new Object[]{i,j});
System.out.println( "result is " + k.toString() + ".");

.net的WEBSERVICE

[WebMethod]   
    public int IntAdd(int a, int b)
    {
        return a + b;
    }
