Developing a JAX-WS POJO Web Service Web services Developing Clients for a JAX-WS Web Service

This tutorial will walk you through building and developing the jax-ws calculator that ships with the samples package for Geronimo. After completing this tutorial, you should be able to understand how to build simple web services with Apache Geronimo 2.1 using the Eclipse development environment

To run this tutorial, as a minimum you will be required to have installed the following prerequisite software.

  • Sun JDK 5.0+ (J2SE 1.5)
  • Eclipse 3.3.1.1 (Eclipse Classic package of Europa distribution), which is platform specific
  • Web Tools Platform (WTP) 2.0.1
  • Data Tools Platform (DTP) 1.5.1
  • Eclipse Modeling Framework (EMF) 2.3.1
  • Graphical Editing Framework (GEF) 3.3.1

Details on installing eclipse are provided in the Development environment section. This tutorial is organized in the following sections:

The application development will take you through the following

Setting Eclipse for Application Development

  1. Create a Dynamic Web Project
    • Select File -> New, select Other...





    • In the popup window select Web->Dynamic Web Project category and click NEXT.





    • Type in jaxws-calculator as the Project name: and select Next





    • On the next screen check the box for Axis2 Web Services





    • Make sure Generate Deployment Descriptor is selected and click Next.





    • Modify the Group Id to: org.apache.geronimo.samples.jws and Artifact Id: to Calculator.



      Useful Information

      Group ID: A name that identifies the group of a module. The default value is default.
      Artifact ID: A name of the module in a group. The default value is <blank>.
      Version: The version of module. The default value is 1.0
      Type: The type of module, such as system module (car), jar module (jar), web
      archive (war), enterprise archive (ear), and so on. The default value is car
      A module is stored inside a repository as repository/groupId/artifactId/version/artifactIdversion.
      type. This repository structure gives a more standardized and easily maintainable
      structure to Geronimo applications.

    • Select Finish.

      Warning

      Depending upon your environment, you may see the error message "Failed while installing Axis2 Web Services Core 1.1". Do not worry. We will just have to manually point Axis2 to the installation directory of WASCE to fix this error.




  2. AXIS2 Configuration
    • Select Window->Preferences.





    • Select Web Services->Axis2 Preferences.
    • Under Axis2 Runtime tab, browse to the installation root of Apache Geronimo. Select Ok.





      This completes the configuration of Eclipse for application development.

Define the wsdl for the web service

  1. Right Click on the WebContent subfolder and Select New->Other.
  2. Select Web Services->wsdl and click Next.
  3. Give the File name as CalculatorService.wsdl and click Next.
  4. On the next window give the Target namespace as "http://jws.samples.geronimo.apache.org". Select Finish.
  5. Modify the CalculatorService.wsdl as follows
    CalculatorService.wsdl
    <wsdl:definitions name="Calculator"
