Farkuldi,
Does the JRE you're using have associated source? In
Window->Preferences->Java->Installed JREs if you Edit... the one(s) you
have, and select one of the jars and click on Source Attachment... is
there one there? You'll want a JDK that comes with a src.jar and use
that as the source attachment.

In fact, I thought this was what the Javadoc view at the bottom of Eclipse was for. However, nothing ever shows up in my Javadoc view. I do get the Javadoc when I hover over something, but this is not exactly what I want.

Thank you for your reply. I looked in that section, and it lists a lot of JRE System Libraries. I clicked on Source Attachment for all of them, though, and none have anything there. I have no idea what I am looking at, though, or what to do. How do I get the src.jar, and when I have it, which one of the JRE System Library entries in that menu do I associate it with? There are about 20 there.
Also, I forgot to mention that I downloaded the Javadocs as a zip file, and through following instructions somewhere else to get the documentation showing, I somehow imported them into this window. This is what I have:

Farkuldi,
You just download a JDK with source. E.g., I think these will contain a
src.zip
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
If you create a new JRE entry and point it at such a JDK with a src.zip
I think they'll be automatically attached.
