jar file doesn't run

Question

I'm fairly new to Java and having recently installed the latest JDK I'm having trouble getting files with a .jar extension to run. When I double-click them I simply get an alert noise and nothing more. I have tried jarfix.exe, tried changing the associated program in folder options and even reinstalling Java. Not sure what else to do. Any help greatly appreciated thanks!

Try running from the command line and see what error messages you get.

java -jar your.jar
