In the Java source from http://download.java.net/jdk6/source/ I get a jar of size ~130mb. The jar don’t attach to Eclipse, and inside it has a file called “X_X” of size ~130mb.
Does anyone know what’s happening?

Thanks Gerco Drie,

now, about this README file:

JDK requires a high level of
technical expertise. (…) If you are not a
technical professional in one of these
categories, this release is probably
not for you.

so, where is the already buid one for me?
I’m using Java 6 update 15.

The site http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/jdkfiles.html says the src.zip is in the root jdk folder (yes, I remember it was last time I needed it), but its not..
Is my jdk a pirate version? 😛

    You need to run the jarfile, not extract it or link it to eclipse. The instructions are here:

    http://download.java.net/jdk6/6u20/promoted/b01/docs/build/README-JRL.html

    These files are jar files that need to be run, not un-jar’d, for example: java -jar filename.jar

    I think BalusC is right by the way, this is not the sourcecode you want. You probably want the rt.jar sourcecode, which is in src.zip with the JDK. What you downloaded is the complete sourcecode of the JVM, hotspot compiler, etc included. Although it also includes the class libraries, there is an easier way.
