In order to run a .jar file, you must have the Java Runtime Environment (JRE) installed. A .jar is like a zip (i think you can even open it with winrar or so) but it is also runnable as Java software if the JRE is installed.
I suppose a JRE is automatically installed if you have the JDK (Java Development Kit) installed.

That suggests that whoever created the jar file may have screwed up. It could be missing a file, have files in the wrong place, etc. Moving things around in the jar file is unlikely to work well. It's also possible that someone renamed the jar file, which will cause problems.

Then, assuming the .jar files contains a .class file with the main method, the .jar file must be corrupt or some kind. :(
The JRE will search for the main method to start running with help from the manifest file which tells the JRE where that main method is. For some odd reason it can't find it. The manifest file should be automatically created when the .jar is being made.
