Build openjdk?

[Peng Yu]

I think that you have misunderstood me.

In my original post, I have already downloaded openjdk-7-ea-src-b71-03_sep_2009.

But before I should install jdk 6, which is on
http://java.sun.com/javase/downloads/index.jsp

I also need the source code to install jdk 6. The source code for jdk6
is http://www.java.net/download/jdk6/6u18/promoted/b02/jdk-6u18-ea-src-b02-jrl-09_sep_2009.jar

My current question is how to install jdk 6?

Regards,
Peng
