Jdk source code

Here's the jdk source, linked from OpenJDK page
I wish they had made a source jar for it.

NOTE: Do not trust mac to extract this .tar.gz correctly. It extracts it as a .cpgz file which then recursively produces another .tar.gz -_-
Use tar -xvzf

Javax servlet source code

Have been searching it for quite a while now, finally found decent jars:
http://grepcode.com/snapshot/repo1.maven.org/maven2/javax.servlet/servlet-api/2.5
http://repository.ops4j.org/maven2/javax/servlet/source/

there is also a pom.xml that can be used :)
