Attaching additional javadoc in Intellij IDEA

Question

When I use quick documentaion lookup (Ctrl+Q) on j2ee classes or annotations in IDEA I only get an empty javadoc. It only contains the basics like class name.

How do

Answer 1

What about documentation for an extension API? I had added the j3d API to my jdk1.6 and use it succesfully, next step, get the javadoc

Forget the links on java.sun.com (It is a mess) Go directly to java.net and get all the stuff (API, javadoc, get the source even -for every package-)

Go to your jdk and selected the documentation path and add the javadoc zip. Go to the source tab and add the source's zip

You're done.

Actually only the source is needed to enjoy javadoc and the uncompiled classes
