Tutorial für kleine Anwendung mit Icon und Mausklick

[jobo]

Hallo,

ein kleines Tutorial habe ich hier schon gefunden. Das öffnet ein kleines Fensterchen, wenn ich in der Kommandozeile eingebe: java HelloWorldSwing. Wenn ich HelloWorldSwing.class im FileBrowser anklicke heißt es "couldnt display...". Wie geht es, dass ich das Programm so habe, dass es a) mit einem kleinen Icon im Filebrowser dargestellt wird und b) es onclick ausgeführt wird?

Hallo,

ich habe jetzt versucht, einen .jar-File herzustellen.

jar cf my.jar input HelloWorldSwing.java

Da kommt auch was raus, aber weder mit rechterMaus "starten mit Java 6 Runtime" noch via Konsole "java -jar my.jar" gehts. Bzw. bei der Konsole kommt: "jar cf jar-file input-file(s)

"Failed to load Main-Class manifest attribute from jarfile.jar"

Hallo,

jar cvfm myjar2.jar manifest.txt *.java

In der manifest.txt steht

Main-Class: HelloWorldSwing

mit Absatz am Ende (Linux).

Nach

jar cvfm myjar2.jar manifest.txt *.java

kommt mit

java -jar myjar2.jar

als Fehlermeldung:

Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorldSwing

Die Klasse heißt aber so und ist ja auch im Manifestfile angegeben ...????

Hallo,

jar cfm myjar4.jar manifest.txt *.class

hats jetzt gebracht. Er erstellt beim kompilieren komischerweise zwei .class-Files, ein HelloWorldSwing.class und ein HelloWorldSwing$1.class. Beide liegen dann in dem "Ordner" myjar4.jar, darin dann der Manifestfolder mit der Manifestdatei. So gehts dann immerhin mit Rechtsklich "open with Sun Java 6 Runtime". Warum aber gehts nicht wie bei "normalen" Programmen einfach mit Doppelklick. Mal angenommen ich wollte eine Wasweißichtaschenrechner mit Java programmieren, eben ganz "normal" mit Taschenrechnericon und Doppelklick?

Tach,

Mal angenommen ich wollte eine Wasweißichtaschenrechner mit Java programmieren, eben ganz "normal" mit Taschenrechnericon und Doppelklick?

du brauchst einen Compiler oder Wrapper.

Hi,

hats jetzt gebracht. Er erstellt beim kompilieren komischerweise zwei .class-Files, ein HelloWorldSwing.class und ein HelloWorldSwing$1.class.

Was soll daran komisch sein?
HelloWorldSwing.class ist eh klar, und das $1 ist für die erste anonyme innere Klasse.
Die wird hier erzeugt:

javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });

Hier wird anonym von Runnable eine Klasse abgeleitet (und die run-Methode überschrieben).

Warum aber gehts nicht wie bei "normalen" Programmen einfach mit Doppelklick.

Weil Du jar-Files nicht entsprechend mit java.exe verknüpft hast im Betriebssystem.

cu,
Andreas
