Lesson 2: Creating and testing the web service

After you create a JAX-RS enabled project, you can download the Java™ files that are used by the application and test the web service.

Create a JAX-RS web service

Download the sample XXX. The project that contains the Java classes that are needed for the application.
In your web project, create a package called com.test (right-click Java Resources > src and select New > Package). Import the following classes from the downloaded project into the package:
- AddressBook.java
- AddressBookApplication.java
Open WebContent/WEB-INF/web.xml. In the Design view, select the Servlet (JAX-RS Servlet) and click Add and add an Initialization parameter to the JAX-RS servlet, leaving the name and value fields empty. Save web.xml ignoring any errors that might be displayed.
In the Problems view, right-click the param-name warning and select Quick Fix. Select to browse for an existing subclass, and select the AddressBookApplication.
Save web.xml.

In the Servers view, right-click your server and select Add and Remove, and add the JAX-RS EAR to the server. Restart the server.
To retrieve all addresses in the Address Book application, open a Web browser and enter the following URL: http://localhost:<default_host_port>/<application_name>/jaxrs/addresses
For example, following the naming convention used in this tutorial and the default port, http://localhost:9080/JAXRS/jaxrs/addresses
Note: For WebSphere Application Server traditional, you can determine the default host port name in the WebSphere Application Server Admin Console server configuration tab.
Enter the following URL: http://localhost:<default_host_port>/<application_name>/jaxrs/addresses/<address index>
The address index is a number in the range 0 - 5 that represents the 6 addresses that are listed in AddressBook.java. The address that is assigned to that index value is displayed.
