JAVA_HOME environment variable and Java JDK fun

I wanted to get Java running at 1.6xxx - I changed the JAVA_HOME variable and pointed it to the directory C:\Program Files\Java\jdk1.6.0._16.

I restart the PC - and I think I can check which version开发者_开发知识库 of Java my machine is pointing at - but it still points to the older version of Java e.g v1.5.0_16

Can you help me rejog my memory on correct setup for Java JDK?

JAVA_HOME is used by other applications, such as Tomcat. Windows just checks the PATH environment variable for locations where it can find the java executable.

Try this on the cmd shell:

> java -version
java version "1.5.0_16"
> set PATH=%JAVA_HOME%\bin;%PATH%
> java -version
