Write about the web server

In a pinch, you can even use your Raspberry Pi as a Web server. You can host a simple site or store files in the cloud so you can access them at any time—no monthly hosting fees, limited templates, or other barriers to your creativity. At its most basic level, a server is a combination of software and hardware that responds to requests across a computer network in order to provide services. The computer network could be as small as your home network or as big as the World Wide Web.

Running the Server

Enter a project name, such as wsServerExample, when prompted, as shown in Figure 6. If you're prompted to switch Java perspective, click Yes. Create the server First you need to create a Java package to house your Java classes: When the New Java Package window opens, enter a name for the package, such as com.

Creating a package View image at full size Next you need to create a class for the server code: Configure it as shown in Figure 8.

Creating a class View image at full size Create your class as public with no main method stub. Now that you've provided your package with a class, you can write the code for the server, as shown in Listing 1. Server code package com. Developers define their classes and methods before applying annotations to them to indicate to the runtime engine how to enable the class and its methods as a web service and web service operations.

Java SE 6 comes bundled with such an engine. The WebService annotation marks the SayHello class as implementing a web service, which results in a deployable web service being produced. See Resources for more information about other annotations in Java SE 6. Generate the server code with Ant After you've written the server application, you need to generate the web service-supporting code.

Creating an Ant file Enter the Ant project shown in Listing 2. Ant build success Return to the Eclipse project and refresh the project by right-clicking wsServerExample and selecting Refresh.

You should now see the generated code to run the web service created under the new package called com. Generated code Publish the web service After you've generated the code for the web service's server, you need to publish it so you can start using it: Create a new class under the com.

Write the code to publish your web service, as shown in Listing 3. Publishing code package com. You should see an indication that the web server has started, as shown in Figure Console with the service running View image at full size View the WSDL Now that the server is up and running, you should test it to make sure it's working as expected: Console with the internal Web browser When you're finished, you can stop the web service by clicking the red square in the Eclipse Console view.
