首先，我还是推荐你使用oracle java。尽管oracle java和sun java，在初学者看来，并不会有多大的差异性。
另外，oracle java对内存的要求比较小，在linux中只需64M即可。
下面是如何安装oracle java 1.6的方法。

代码： 全选

sudo add-apt-repository "deb http://archive.canonical.com/ubuntu lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin
sudo update-alternatives --config java

需要注意的是，你需要把第一条命令中的lucid替换成你的ubuntu版本的开发代号。

OpenVZ的VPS不支持Java的.
建议买Xen的VPS.

如果试图安装 openjdk，会有如下报错：
perl: warning: Falling back to the standard locale (”C”).
我耗费时日而不得其解。后来搜到一片同人的说法：在 openVZ 的虚拟机上，只能用 ibm 的 JVM, Ref: http://www.geektu.com/?p=641

装了ibm的java ,谢谢！
