Netbeans missing a dependancy

[Jonas Thomas]

Binary package hint: synaptic

When I fire up Netbeans, it returns this error message:
Warning - could not install module JPDA Debugger API
    JPDA Debugger API - This module requires JDKHOME/lib/tools.jar to be accessible.
This file was not found. Usually this means you are trying to run the IDE with the JRE instead of the full JDK.
If so, please use the --jdkhome command line option to specify a JDK installation.

The fix I found at http://ubuntuforums.org/showthread.php?p=5224928
sudo aptitude install sun-java6-jdk

appears to work.
