I cannot execute .jar files on my MAC

Hi everybody, I have a big problem...

I bought a mac and I cannot open many of the .jar files I had on my previous PC.

There are a couple of .jar files that I can open (like a chronometer).
But I cannot open 90 % of the many other .jar files I have on my mac.

Here is an example if I want to open Cube Explorer. I double click on its icon and the following window comes out:

Schermata 2010-11-04 a 11.19.44.png

then I check the console and there are the following information:

Schermata 2010-11-04 a 11.20.45.png

I don't know what to do… Please help me!

I have the following java version at the moment and I think it is the last one:

Thank you in advance for your help!

Federico

The above exception is thrown when a JVM encounters an unsupported class version. This occurs when the JVM encounters a class built for a later JVM. So you need to upgrade your VM, then change your default Java.

Here's how to change your default:

Type 'java preferences' into Spotlight. You'll see the 'Java Preferences' utility. Run that, and you can change the default Java instance to what you require (probably Java 6).

You are trying to launch the AnimCube applet as an standalone application. You can't do that.

Cube Explorer is a Windows only program at the moment so you won't be able to run it directly on your mac. You could run it using bootcamp or parallels though.
