JAR - File aus dem Code Starten

[Oli]

Hi,

ich habe foldgendes Problem

Runtime.getRuntime().exec("notepad.exe");

funktioniert (alle exe´s).

Runtime.getRuntime().exec("myApp.jar");

liefert folgende Exception:

Wie kann ich denn ein Jar-File ausführen. Also quasi der Runtime sagen mit welchem Programm das jar file gestartet werden soll?

java(w).exe aufrufen

 

[L-ectron-X]

Oder die Jar-Datei in den Classpath aufnehmen und eine Instanz der Main-Class aufrufen.
