下载源码包 sun-java6:
The JDK(TM) is a development environment for building applications, applets, and components using the Java programming language.
This package does not contain the Java Documentation for the Java(TM) Development Kit (JDK). The Java Documentation (jdk-6-doc.zip) may be downloaded from http://java.sun.com/javase/downloads/ and, if placed in /tmp (with root.root ownership), this package will install the Java Documentation with the corresponding JDK.
Note that the Japanese version of the documentation (jdk-6-doc-ja.zip) may alternately be used.
NOTE: you cannot currently use this package to have both English & Japanese documentation installed simultaneously
