TOTD #98: Create a Metro JAX-WS Web service using GlassFish Tools Bundle for Eclipse


Now that you've installed GlassFish Tools Bundle for Eclipse 1.1, lets use this bundle to create a simple Metro/JAX-WS compliant Web service and deploy on GlassFish. These steps will work with either Eclipse 3.4.2 or 3.5 with WTP Java EE support.

  1. Lets create a simple "Dynamic Web Project" as shown below:


  2. Name the project "HelloMetro" and take all other defaults:



    Click on "Finish" to complete the project creation.
  3. Metro allows to create a Web service from a POJO class. So let's add a POJO to the project by right-clicking on the project and selecting "New", "Class" as shown below:

      

    Specify the package name as "server", class name as "HelloService" and click on "Finish".
  4. Add a simple method to the newly generated class as:

    public String sayHello(String name) {
          return "Hello " + name + "!!";
    }
  5. Expand the project, go to "HelloService.java" in "server" package, right-click, select "Web Services", "Create Web service".
  6. Click on "Web service runtime: Apache Axis" and select "Metro (JAX-WS) Runtime" as the Web service runtime as shown below:

  7. Move the slider on the left to top. This will enable testing of the deployed Web service. The completed configuration looks like:



    and click on "Next >".
  8. Select the checkbox "Copy Metro library jars to the project" to resolve the references correctly as shown below:



    and click on "Next >". This bundles the application and deploys to GlassFish and provides an option to test the deployed Web service as shown below:



    Clicking on the "Launch" button shows the following output in the browser:



    The WSDL is hosted at "http://localhost:8083/HelloMetro/HelloServiceService?wsdl".
  9. Click on "sayHello" method, click on "Add" and enter the value as "Duke" as shown below:



    Click on "Go" and the response is shown as:



    Clicking on "Source" in the response window shows the SOAP request/response messages as shown below:

  10. Alternatively, you can click on "Finish" to complete the dialog. Then click on "Run" menu item, "Launch the Web Services Explorer" to see a screen as:



    Enter the URL of the WSDL in "WSDL URL" box as "http://localhost:8083/HelloMetro/HelloServiceService?wsdl" and click on "Go". Now you are seeing the similar screen to test the Web service within the integrated browser as shown below:


A future blog will cover how to write a database-enabled application using the bundled Dali JPA Tools and MySQL pre-registered JDBC driver.

TOTD #97: GlassFish Plugin with Eclipse 3.5


A new version of GlassFish Tools Bundle for Eclipse (ver 1.1) was recently released. The build contains
  • Eclipse 3.4.2 IDE with WTP Java EE support
  • GlassFish v2.1 pre-registered and configured
  • GlassFish v3 Prelude pre-registered and configured
  • JavaDB sample database pre-registered and configured
  • GlassFish Plugin (1.0.29)
  • MySQL JDBC driver registered to the IDE
  • Maven m2 plugins
  • JAX-WS Metro plugin
  • GlassFish documentation
  • And optionally, a JDK 1.6.
The functionality is also available in GlassFish Plugin that can be installed on Eclipse 3.5. However because of the Eclipse bug #280365, the plugin cannot be installed directly using Server Adapters. The alternative is to install explicitly using the Update Site. The instructions to do the same are given below:
  1. In "Help", "Install New Software", click on "Available Software Sites":

  2. Search for "ajax" to see the output as:

  3. Click on "Enabled" button to enable the site and see the change as below:



    click on "OK".
  4. Expand the drop-down list box and chose the recently added "update site" as shown below:



    and it shows all the software available from that site as:

  5. Take the defaults, click on "Next" and it shows the GlassFish plugin version number as shown below:

  6. Click on "Next", accept the license by clicking on  "I accept ..." and click on "Finish" to start the installation.



    The IDE restarts after the installation is complete.
  7. Now a new server can be added using "Servers" tab and it shows GlassFish as an option as shown below:

The screencast #28 shows how to create a simple web application using GlassFish v3. Future blogs will show how to leverage the new functionality of JAX-WS Web services plugin and JPA Dali Tooling with GlassFish.
