My computer won't open any .jar files

Any .jar file, rsbuddy, a pserver, none of them open.
Can someone help me? I have the latest version of java, restarted comp, etc :|

 

Try downloading Java JDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html) and Java JRE (http://www.oracle.com/technetwork/java/javase/downloads/jre-6u26-download-400751.html)

If that doesn't work, please expand on what you mean by 'it doesn't open'.

 

Well i just downloaded java a few days ago and now it says i have an outdated version
It works now lol, thank you. And what i meant was when i double click the jar file, nothing happened, not much more to explain

 

Alright, you're welcome
