Ubuntu: Javadoc

The Javadoc tool is used to generate documentation from comments in Java source code. To generate documentation in Eclipse, choose Project → Generate Javadoc. You may be required to provide the path to the javadoc binary in the Javadoc command field. This is typically /usr/bin/javadoc.

On a typical installation of Eclipse in Ubuntu 9.10 (Karmic Koala), you may not find the javadoc binary. To get this binary, install the openjdk-6-jdk package.
