.jar files not opening

Hi,

When I double-click on a .jar file (installer.jar for example), it does absolutely nothing. Nothing happens. No errors, no windows, nothing. This is specifically for a Minecraft mod but it has also happened when trying to access a Blackboard online conference. I saw a topic that someone had a similar issue and was told to do 'java -jar (drag file here)' and it just told me it could not open.

This is what it said after trying that:

k*****-s******s-macbook-pro:~ k**********n$ java -jar /Users/k***********n/Downloads/Shaders\ 2/INSTALLER.jar
Unable to launch "/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java" (88)

I am operating on Leopard.
