In addition, you must make sure that J2SE? 5.0 is the default version of Java on your system:
In Windows, go the Control Panel and double-click "Java" (if no "Java" icon appears, then you do not have Java properly installed). Choose the "Java" tab at the top and click on "View..." on "Java Application Runtime Settings." Make sure that a platform version 1.5 or higher is checked as "Enabled" and at the top of the list.
Note that older releases of J2SE? 5.0 from Apple do not make their installation the default version of Java on your system; you must set this option in the Java Preferences Utility which can be found in /Applications/Utilities/Java/J2SE 5.0/
To verify your Java installation: At the Windows command prompt, cygwin shell, or OS X Terminal, type java -version and make sure your build is at least version 1.5.0 or higher.
Note: OS X users should use the "cross-platform" version.
