InstallJammer: script to check the JRE is installed

Hi, community.

I'm using InstallJammer, the installer-maker software from Damon Courtney.

I'm writen a small Java application, and want to make a installer.
It's obvious I can't include the JRE into the installer as optional, since it's so huge.
So I've included an action that displays a message typing: Hey, you must have the JRE installed, download it from www.java.com, etc.

My problem: the users frecuently don't know if they have installed the JRE or not. So I want this message to be conditional, but I don't know how to check if the JRE is installed with a
script condition.

Any idea? Thanks for the answers.
