Code searching / browsing / cross referenced web sites

Question

I have stumbled across many websites that sites that let you search and browse code across many different open source projects. Some even have cross referenced capabilities and code syntax highlighting.

But I have not found a goto one. I always stumble onto them from google because I'm usually looking for the source for a particular Java class and I don't want to download the entire source.

Know of any good code browsing websites (particularly for Java)?

I particularly like the format of: http://sorcerer.hudson-labs.org/ but its only for one project.

Answer 1

Most of the time I use grepcode for this kind of browsing.

Answer 2

Sorcerer project can be found here https://sorcerer.dev.java.net/
