Put the jar file in the JRE lib/ext directory

[Avoid - fragile] This directory is automatically searched by the compiler and runtime systems for needed packages. In my Windows installation of Java, the JRE is installed twice, once with the JDK and once so I put it in both. I don't know that both are actually used, but I didn't want to take any chances.

    C:\Program Files\Java\jre1.6.0\lib\ext\
   C:\Program Files\Java\jdk1.6.0\jre\lib\ext\
