Web Service

Server side

Calculator.java

package web;

import javax.jws.WebService;

import javax.jws.WebMethod;

import javax.jws.WebParam;

import javax.ejb.Stateless;

@WebService(serviceName = "Calculator")

@Stateless()

public class Calculator {

     /**

     * REMOVE THE DEFAULT OPERATION, DRAG AND DROP NEWLY CREATED OPERATIONS

     */

    @WebMethod(operationName = "add")

    public int add(@WebParam(name = "a") int a, @WebParam(name = "b") int b) {

        //TODO write your implementation code here:

        return a+b;

    }

   

    @WebMethod(operationName = "multi")

    public int multi(@WebParam(name = "a") int a, @WebParam(name = "b") int b) {

        //TODO write your implementation code here:

        return a*b;

    }

}

Client Side

Crate a console client application.

Right click > other > web service client > add the project

(Before that deploy the web service app)

Pass the values in sever side main method

package calculatorclient;

public class CalculatorClient {

   

    public static void main(String[] args) {

        int x = add(10, 5);

        System.out.println(x);

    }

    private static int add(int a, int b) {

        web.Calculator_Service service = new web.Calculator_Service();

        web.Calculator port = service.getCalculatorPort();

        return port.add(a, b);

    }

   

}

//if you use c# application

//Add the wsdl url to sevice reference

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void button1_Click(object sender, EventArgs e)

        {

            CalculatorWS.CalculatorClient calc = new CalculatorWS.CalculatorClient();

            int x = calc.add(1, 2);

            MessageBox.Show(Convert.ToString(x));

        }

    }

}

WebApplication1

//Server side same

@WebService(serviceName = "Converter")

@Stateless()

public class Converter {

    double celcious = 0.0;

    double faran =0.0;

   

    @WebMethod(operationName = "CelciouseToFaranheight")

    public double CelciouseToFaranheight(@WebParam(name = "value") double value) {

        //TODO write your implementation code here:

        faran =celcious * 1.8 + 32.0;

        return faran;

    }

//Client side

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)
