You got that error because the Java JDK is not on the path. First download and install the Java JDK. Once installed you can do one of two things:

1. Use the new Java JDK 6 as the installed JRE in Eclipse. To do this, go to Eclipse - Preferences. Select Java - Installed JREs and add the JDK.

2. You can append the Java JDK bin path to the Windows path.

I recommend the first option since it is easy to setup.
