Create a java webservice using STS

Below steps explains the how to create a web-service in java in bottom-up approach using the STS(Spring tool suite) IDE. In the bottom-up approach, first we will create a template class, using the template class we will generate the WSDL and deploy the service in servers. Follow the below steps to create a webservice.

Step 1: Create a new java project using the steps mentioned here

Step 2 : Create a template Java class as service

Create a Java class in src folder of the in.javatutorials package as below


Provide the package name and class name into respective fields and click on finish button.


Implement the Java methods as give below:

write the class

Use the below source code to write the class:

package in.malliktalksjava;

* Calculator class exposed as a webservice
* @author malliktalksjava
* @since Version 1.0
public class Calculator {

* adds the two input parameters and return the result
* @param var1
* @param var2
* @return
public Integer addition(int var1, int var2) {

Integer result = var1 + var2;
System.out.println(“addition result in service : ” + result);
return result;

* multiply the two input parameters and return the result
* @param var1
* @param var2
* @return
public Integer multiplication(int var1, int var2) {

Integer result = var1 * var2;
System.out.println(“multiplication result in service : ” + result);
return result;

* divide the two input parameters and return the result
* @param var1
* @param var2
* @return
public Integer division(int var1, int var2) {

Integer result = var1 / var2;
System.out.println(“division result in service : ” + result);
return result;


Step 3: make the java class as web service

Select the Java class as below

choose service methods

The folder structure of the web application looks like below:

webservice folder structure

Deploy the service into tomcat web server and access the WSDL file using the below url:



Finally your web service is ready to use and WSDL url is the end point url for your web service.
