Symptom
You need to run a java application from a jar file on the command line.
Cause
Sometimes you get a jar...
Solution
When the jar has a manifest file in it (which is normal) you can just run it like this:
java -jar MyClass.jar
This will run the java application.
A manifest looks like this:
Manifest-Version: 1.0
Main-Class: myPaket.MyClass
Class-Path: .
You can even rename the jar file because the manifest includes the needed information for the start of the application.
