在学习使用Hudson进行持续集成时，总是报这样的错误：

can't open C:\Program Files\Java\jdk1.5.0\lib\tzmappings.

尽管我设定了JAVA_HOME变量的值，但是每次Hudson显示的系统只java.home 都是 C:\Program Files\Java\jre6\

不得已在Hudson的 Global properties -> Environment variables 种手动添加了java.home 为 C:\Program Files\Java\jdk1.6.0_13。但是类似的错误仍在继续。

正在一筹莫展时，发现Maven的java home 也不是JAVA_HOME的，而是其下的jre文件夹： Java home: C:\Program Files\Java\jdk1.6.0_13\jre

照这个值将Hudson的 java.home改为 C:\Program Files\Java\jdk1.6.0_13\jre，即可

上网查了一下，没找到他们之间的详细区别，以后再碰到时再探究原因吧
