The Show hits to developer support link on the Developer Support index page toggles the

tracking of requests against the Developer Support application itself. As most developers will

not be interested in this information, this information is usually left hidden.

7.4. Setting Up Eclipse and WAF

The following sections describes how to set up a WAF development and debugging environment

within Eclipse, an open source Integrated Development Environment (IDE).

7.4.1. Installing Eclipse

1. Install WAF — install as normal, using the RPM’s and WAF Autobuild system. For more infor-

mation, see the Red Hat Web Application Framework Installation Guide:.

2. Install Eclipse — Eclipse can be obtained from http://www.eclipse.org. Install using RPM, if

possible.

In order to take advantage of the anti-aliased fonts within Eclipse, use a build of Eclipse designed

for the GTK in Red Hat Linux 8.0 and later.

3. You may also wish to install the Perforce, Resin, and JavaCC plugins for Eclipse, which can be

found at:

• http://sourceforge.net/projects/p4eclipse

• http://www.improve-technologies.com/alpha/resin

• http://sourceforge.net/projects/eclipse-javacc

4. To install the Perforce and Resin plugins, use the Eclipse Update Manager by selecting Help =

Software Updates = Update Manager. Next, add bookmarks for the download URLs listed

by the plugins’ Web sites. The Update Manager can then automatically download and install the

Perforce and Resin plugins.

To install the JavaCC plugin, download the plugin and unzip it in Eclipse’s plugin directory. Then,

follow the instructions in the plugin’s README ﬁle.

5. Install Resin — if you are using the Resin application server. You may download Resin at Cau-

cho’s website: http://caucho.com. You may also want to download the source code for Resin in

order to trace through its code when debugging.

7.4.2. Eclipse Preferences Conﬁguration

To set preferences within Eclipse, go to Window =

Preferences. Noteworthy preferences include:

• Workbench = Editors. There is a key bindings option where you can select Emacs key bindings.

• Java = Compiler = Errors and Warnings. You probably only want to select Error for the

options:

• Unreachable code

• Resolvable import statements
