Maven Webstart Plugin

Hallo,

nach mehreren Stunden suchen und probieren möchte ich maven ..........

Ich würde gerne ein Maven-Projekt aufsetzen, dass mir automatisch ein Webstart-Anwendung erstellt, ohne die blöden key-tools Befehle manuell eingeben zu müssen und trotzdem ein Sign-Jar erhält. Sprich alle Informationen sollen in der pom stehen. Das muss doch gehen.

Über eine Lösung würde ich mich sehr sehr freuen

Gruß,
Thomas
 
Ich komm nicht mehr weiter :-(

Damit sich Fragen zur Projektstruktur erledigen habe ich das Projekt mal angehängt. Beim Build erhalte ich folgende Fehler in der Console
Build mit der Option -e

Hallo,

also ich habe das Ding mal etwas genauer angeschaut...Die Meldung rührt daher, dass die mainClass nicht korrekt konfiguriert ist (Quelltext und Exception Ausgabe)....Das scheint die Ursache zu sein....Aber leider weiß ich auch nicht wie man es richtig macht...

Danke für den Tipp mit der MainClass. Ich dachte immer, dass es an der Konfiguration liegt.

Mit dem Eintrag
Java: 
<mainClass>org.apache.commons.cli.BasicParser</mainClass>
funktioniert es. Komisch, da wiedersprechen sich die Beispiele auf der Homepage des Projektes. Mals so, dann so 🙂
 
Ok. Das war es nicht. Hmm, ich habe nun die Orginal-POM kopiert und mainClass wieder auf meine Klasse gesetzt. Jetzt kompiliert alles schön durch und der sign-Check wird erfolgreich durchgeführt.

Nun gibt es ein anderes Problem. Ich bekomme beim ausführen aus einer Website eine NullPointerExc.
Linux-Console:
Code: 
javaws http://enzinger-th.de/webstart/test/Test2.jnlp
net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file.

Test2.jnlp
Code: 
<?xml version="1.0" encoding="utf-8"?>

    spec="1.0+"
    codebase="$$codebase"

<jar href="commons-cli-1.2.jar" version="1.2"/>

  </resources>
  <application-desc main-class="edu.regensburg.tm.temp.test.test2.App"/>
</jnlp>

Verwende ich die Source in einem Netbeans-Projekt und kompiliere es als Webstart funktioniert es
Code: 
javaws http://enzinger-th.de/webstart/test/launch.jnlp
