Add the new Java bin folder to your path. And remove any other java references from your path.

You should set the PATH environment variable. On the command prompt, do:

> set JAVA_HOME=c:\java\jdk1.6.0_20
> set PATH=%JAVA_HOME%\bin;%PATH%

Now doing java -version should give you the expected version information.

The JDK install does not update the default Java installation on the system.

Go to http://java.com/en/download/installed.jsp and use the suggested installation procedure there when it finds that your default Java is outdated.
