JDK Source code

Does the source code for the standard java libraries come with the sdk? I thought that was the whole point of an sdk, but when using eclipse, it says it cant find the source (in rt.jar), and just gives me an outline of the class. Do I separately have to download the source code? I saw something like this somewhere on the site (SCSL or JRL), but am not too sure if that's what i'm looking for...

Cheers,

Siam
