Installing and configuring JDK 5.0, JBoss 4.0.5, and Eclipse SDK 3.2.1 (including plug-in) required many steps.
During the installation, each individual component was installed and run. So it is known that each component runs OK. In this section, the components are tested together. In this way installation problems can be found and rectified.
The easiest way to test the installation, is to write a small project which uses all the components that have been installed.
A bonus of this step is that each component is used, and therefore some idea of how these components are used and configured begins to be learnt.
NOTE: The source code for installation tests can be downloaded as a zip archive.
