"Ich glaube nicht, dass die Windows-Programme unabsichtlich ausgerechnet die Teile eine Paketarchivs verschweigen, die die Metadaten und Installationsskripte des Pakets beinhalten."
Hehe... definitiv ein Schelm, wer sich Böses dabei denkt!
So macht man das bei Windoof, ein Java-Programm schreiben mithilfe der Apache Commons Compression Library v1.12 mit Java Version 1.6-Compile, damit man das .jar-File anschliessend per IKVM.NET (
http://www.ikvm.net/) in eine .NET-exe umwandeln kann. (IKVM.NET unterstützt glaube ich nur Java 1.6 - deshalb auch die Apache Commons Compression Library in der Version 1.12)
