574 CHAPTER 12 • Adding New Servers Figure 12.10 New Launch Configuration 4. You should see your GlassFish server adapter listed now. Select GlassFish and click the Next button. The GlassFish Runtime wizard opens (see Figure 12.12). Note how the wizard UI gets populated with form fields for the runtime properties you defined in the server definition file. 5. Specify the location of the GlassFish installation directory. Enter the loca- tion or select it using the Browse button. Note that a directory browse but- ton has been provided because the type of the property was directory. Click the Finish button. The Installed Runtimes preference page now lists GlassFish (see Figure 12.13). 6. You have now added the GlassFish server runtime environment and are ready to use it for a new Web project. In the Project Explorer view, right click and select New ᭤ Dynamic Web Project. The New Dynamic Web Project wizard opens (see Figure 12.14).

Enter TestWebProject as the project name and select GlassFish as the target runtime. Click the Next button. The Select Project Facets page is displayed (see Figure 12.15). Figure 12.15 Select Project Facets 8. Notice how the set of supported facets matches the allowed values that were defined in plugin.xml. Accept the defaults for other properties. Click Finish. WTP creates the project. Notice that a GlassFish library gets added to the proj- ect as defined by the runtime classpath provider extension (see Figure 12.16). 9. Create a simple JSP named index.jsp in the WebContent folder. Add some simple content to it. This completes the project setup. 10. You are now ready to run the JSP on GlassFish. In the Project Explorer, select index.jsp, right click, and invoke the Run As ᭤ Run on Server menu item. The Run On Server wizard opens (see Figure 12.17). 11. Create a new server configuration for the GlassFish runtime. Click Next to continue. You will see the server properties displayed (see Figure 12.18). These properties were also defined in the server definitions file. Enter the proper values. 12. Click Next to continue. The Add and Remove Projects page is displayed (see Figure 12.19). 578 CHAPTER 12 • Adding New Servers Figure 12.16 Dynamic Web Project—TestWebProject Figure 12.17 Define a New Server Testing the Server Adapter 579 Figure 12.18 GlassFish Server Figure 12.19 Add and Remove Projects 580 CHAPTER 12 • Adding New Servers Figure 12.20 Run On Server—index.jsp 13. A server configuration includes the list of dynamic Web projects. TestWebProject was automatically added for you, so simply click the Finish button. The wizard creates the server, starts it, publishes the TestWebProject project to it using the Ant scripts, and launches the Web browser using the URL for the JSP (see Figure 12.20). As the server starts and publishes, messages are displayed in the Console view. Summary In this chapter you learned about the server tools and how to extend WTP with a new generic server adapter. You developed and tested a generic server adapter for GlassFish. Summary 581 There is more to server tools than what was covered here. Generic server support is suitable for most purposes. However, you should also have a look at the custom adapters, such as the Tomcat plug-ins, to see how you can have full control over the server tools capability. If you would like to learn how to publish your server plug-ins as installable features, and provide links to your update sites, you should look at the Apache Geronimo plug-in.

While some of the artifacts, such as server instances, may be intangible, most artifacts map to one or more files whose syntax is defined by programming languages. The IDE’s job is to simplify the task of working with these languages. There are a number of tools an IDE can provide to simplify development of language-specific files. A new file wizard handles tasks such as naming and place- ment of the file and can create a skeleton structure of the new file. A rich editor simplifies manual editing of the file with content assistance and syntax highlight- ing. Rich editors may also include a design or graphical view that provides an alternate visualization of the file. A validator, which will typically be integrated with the editor, checks the file to ensure it is compliant with the language specifica- tion. If a file requires compilation or some other form of transformation before it can be deployed, a facility for building the file should also be included. DocBook is an XML language for authoring documents such as books, articles, and reference pages (see Example 13.1). It can be obtained from the DocBook Web site: http://www.docbook.org Example 13.1 Listing of article.docbook <?xml version="1.0" encoding="UTF-8"?> <article> <title>Supporting New File Types</title> <para> At its core, an integrated development environment (IDE) assists a developer in working with various development artifacts.
