I don't know if Oracle/Sun publishes a list of which jars to include or where they get it but my Eclipse project using Java 8 update 40 has 18 jars listed there.

     I could be wrong, but I don't think that's the O.P.'s problem.
He wrote "I create an UI" that finds and lists classes (sounds like
a sort of auto-completion thing), in somewhat the manner of an IDE.
So I think the issue isn't "How do I tell my IDE where rt.jar is?"
but "How does a piece of executing code find the rt.jar its JVM is
using?"
