Part 1 : Calling a webservice from Android Application

Calling a webservice from Android app

There are two parts

Part 1: Creating a WSDL Service.

Part 2: Calling A WEB SERVICE from Android App.


Part 1: Creating a webservice


  • Prerequisite: Eclipse which supports web development.
  • Download Axis2-1.4 from
  • Download the zip version of “Standard Binary Distribution”.
  • Extract in the desired folder and keep a note of its location.
  • Open Eclipse. Go to Window -> Preference and you will get the following screen

  • Click on “Web Services -> Axis2 Preferences”
  • Browse the directory to the location, where we have extracted The “axis2-1.4”
  • We should get the following screen “Axis2 runtime loaded sucessfully”.

  • Click “OK”
  • Create a new “Dynamic Web Project”

  • Make sure Server is configured Properly.
  • Click Finish.
  • Create a new package. Right Click on “src -> New -> Package “

  • Click Finish.
  • Create a new Java class inside the same Package.

  • Click Finish.
  • package org.web.backend.calculator;
  • Create class “Calculate” inside the package, with following methods.
    public class Calculate {
    public int sum(int i, int j) {
    return (i + j);
    public int subtract(int i, int j) {
    return (i – j);
    }public int multiply(int i, int j) {
    return (i * j);

    public int divide(int i, int j) {
    return (i / j);

  • Save the file.
  • When services are deployed to Axis, the wsdd file is used during the deployment and its contents end up within server-config.wsdd in /usr/local/OMII/jakarta-tomcat-5.0.25/webapps/axis/WEB-INF.
  • Since we dont have such file, we have to create a “server-config.wsdd”
  • Right Click on “WEB-INF” and select “New -> File”. Name it as “server-config.wsdd”.
  • The contents can copy pasted from this link
  • Make sure you have the following jar files inside the library of created Project.
  1. activation.jar
  2. commons-discovery.jar
  3. jaxrpc.jar
  4. mail.jar
  5. saaj.jar
  • These jar files are required for successful completeion of creation of WSDL service. So if you dont have kindly download it inside the lib folder of axis2-1.4, as shown below.


  • So now we to copy paste all the library from bin folder inside the lib of project
  • From : C:\Users\j3 d patel\jars\Axis2\axis2-1.4\lib
  • To : WEB-INF\lib
  • Now Project Explorer looks like the following screen shot

  • Right Click the Java Class we created “”.
  • New -> WebService.

  • Click Next
  • Click on Web Service runtime : Apache Axis
  • Select Apache Axis 2 and click OK. Finally it should look like the foloowing screen shot.

  • Select Next.

  • Select Next and then click “Start Server.”
  • Click “Next”

  • If you get the following screen, everything is working fine.
  • Click on Services.

  • If you get the above screen, we have sucessfully created a wsdl file. The only step Remaining is to click on “Calculate”.
  • If it points to “http://localhost:8080/AndroidBackend/services/Calculate?wsdl” with a wsdl file in your web browser, We have successfully created a wsdl file for our android app.
  • Keep a note of this wsdl url as it will be required in Part 2.
