The Java EE 5 Tutorial

The Example JSP Pages

This chapter illustrates JSP scripting elements using webclient, a version of the hello1 example introduced in Chapter 3, Getting Started with Web Applications that accesses a web service.

To deploy and run the webclient example using NetBeans IDE, follow these steps:

1. Build and deploy the JAX-WS web service MyHelloService described in Building, Packaging, and Deploying the Service.

2. In NetBeans IDE, select File→Open Project.

3. In the Open Project dialog, navigate to:

   tut-install/javaeetutorial5/examples/jaxws/

4. Select the webclient folder.

5. Select the Open as Main Project check box and the Open Required Projects check box.

6. Click Open Project.

7. In the Projects tab, right-click the webclient project, and select Undeploy and Deploy.

8. To run the application, open the bookstore URL http://localhost:8080/webclient/greeting.

To deploy and run the webclient example using ant, follow these steps:

1. Build and deploy the JAX-WS web service MyHelloService described in Building, Packaging, and Deploying the Service.

2. In a terminal window, go to tut-install/javaeetutorial5/examples/jaxws/webclient/.

3. Run ant. This target will spawn any necessary compilations, will copy files to the tut-install/javaeetutorial5/examples/jaxws/webclient/build/ directory, will create a WAR file, and will copy it to the tut-install/javaeetutorial5/examples/jaxws/webclient/dist directory.

4. Start the Application Server.

5. To deploy the example using ant, run the following command:

   ant deploy

6. To run the example, open your browser to http://localhost:8080/webclient/greeting.

To learn how to configure the example, refer to the deployment descriptor (the web.xml file), which includes the following configurations:

• A display-name element that specifies the name that tools use to identify the application.

• A set of servlet elements that identify the application’s JSP file.

• A servlet-mapping element that defines the alias to the JSP file.

  Note - The example assumes that the Application Server runs on the default port, 8080. If you have changed the port, you must update the port number in the file tut-install/javaeetutorial5/examples/jaxws/webclient/response.jsp before building and running the example.
