Java calls methods of the WebService interface

This article illustrates how Java calls the WebService interface. Share with you for your reference. The details are as follows:

Here is the reference method Add, the code is as follows:

public static void addTest() {

        try ...{

            Integer i = 1;

            Integer j = 2;

            

            //WebService URL

            String service_url = "http://localhost:4079/ws/Service.asmx";

            

            Service service = new Service();

            Call call = (Call) service.createCall();

            call.setTargetEndpointAddress(new java.net.URL(service_url));

            

            //Set the method to be called 

            call.setOperationName(new QName("//www.jb51.net/T", "Add"));

            

            //The parameters required for this method are 

            call.addParameter("a", org.apache.axis.encoding.XMLType.XSD_INT,

                    javax.xml.rpc.ParameterMode.IN);

            call.addParameter("b", org.apache.axis.encoding.XMLType.XSD_INT,

                    javax.xml.rpc.ParameterMode.IN);

            

            //Method returns a value of type 

            call.setReturnType(org.apache.axis.encoding.XMLType.XSD_INT);

            

            call.setUseSOAPAction(true);

            call.setSOAPActionURI("//www.jb51.net/Add");

            

            //Call the method 

            Integer res = (Integer)call.invoke(

                    new Object[]...{

                        i, j

                    }

            );

            

            System.out.println( "Result: " + res.toString());

            

        } catch (Exception e) ...{

            System.err.println(e);

        }

}

Run, and the Result returns: Result: 3
