JAX-WS stands for Java API for XML Web Services. It is a Java programming language API for creating web services and clients that communicate using XML. This post is a quick start for JAX-WS.

GlassFish integrated with Eclipse.

Creating the JAX-WS Web Service
  1. In Eclipse create a Dynamic Web Project called "com.eviac.blog.jaxwsproj". Make GlassFish as the Target Runtime.
  2. Create a new class called "SampleWS" in the created project. This will be the implementation class of the web service.
    package com.eviac.blog.jaxws.service;
    import javax.jws.WebMethod;
    import javax.jws.WebService;
    public class SampleWS {
     public int sum(int a, int b) {
      return a + b;
     public int multiply(int a, int b) {
      return a * b;

  3. Open a terminal and navigate to the root of the project directory. Create a directory called wsdl inside WebContent/WEB-INF/. Use the following command to create web service artifacts. Make sure your JAVA_ HOME is set properly or this command will not work. Also make sure to build the project before running this command or it will complain class not found.
    wsgen -classpath build/classes/ -wsdl -r WebContent/WEB-INF/wsdl -s src -d build/classes/ 
  4. Refresh the project to discover created artifacts. Open the created WSDL-file inside wsdl folder. Search for REPLACE_WITH_ACTUAL_URL and replace it with the web service URL: http://localhost:8080/com.eviac.blog.jaxwsproj/SampleWSService, and save the file.
  5. Deploy the project in Glassfish by right-clicking the project, click Run As -> Run on Server and select the Glassfish server.

Creating the JAX-WS client

  1. Create a Java project in eclipse called "com.eviac.blog.jaxwsclientproj". Open up a new terminal and go to the project root. Use the following command to generate the classes you need to access the web service. Here you will need to use the URL of the WSDL file.
        wsimport -s src -d bin http://localhost:8080/com.eviac.blog.jaxwsproj/SampleWSService?wsdl  

  2. Create a new class called "SampleWSClient" in the project.
    package com.eviac.blog.jaxws.client;
    import javax.xml.ws.WebServiceRef;
    import com.eviac.blog.jaxws.service.SampleWS;
    import com.eviac.blog.jaxws.service.SampleWSService;
    public class SampleWSClient {
     @WebServiceRef(wsdlLocation = "http://localhost:8080/com.eviac.blog.jaxwsproj/SampleWSService?wsdl")
     private static SampleWSService Samplews;
     public static void main(String[] args) {
      SampleWSClient wsClient = new SampleWSClient();
     public void run() {
      Samplews = new SampleWSService();
      SampleWS port = Samplews.getSampleWSPort();
      System.out.println("multiplication Result= "+ port.multiply(10, 20));
      System.out.println("Addition Result= "+port.sum(10, 20));
  3. Right click on the project and click on Run As -> Java Application. This will result following.
    multiplication Result= 200
    Addition Result= 30
