Schach in Java-Applet <No main classes found>

[Ego_Akkarin]

Hi

Ich habe habe mir selbst das Ziel gesetzt ein Schach mit gegnerischer KI zu programmieren, da ich gern ein GUI hätte habe ich es in Java-Applet realisiert.

Nun kurz vor Schluss habe ich ein Problem... (wer häts gedacht)
Immer wen ich das Applet starten will erhalte ich die Fehlermeldung <No main classes found>(die Fehlermeldung ist im Anhang
Ich arbeite mit Netbeans und dies ist eins meiner ersten Projekte in JavaApplet

package chess;

import java.applet.Applet;
import java.awt.*;

public class ChessPartner extends Applet
{
	//reference for the board classDie Referenz auf die KI
	board brain;

	//the elements of the GUI
	Button newgame = new Button ("start new game");

//events
public boolean action (Event evt, Object arg) {
	if ( ((String) arg).equals ("start new game"))
		brain.newgame ();	
	return true;
}
//initialize the applet
public void init() {
	super.init();

	//initialize AI
	brain = new board (this);
	
	//build GUI
	setBackground (Color.lightGray);
	setLayout (new BorderLayout (10,10));
	
	add ("Center", brain);
	add ("South", newgame);	
}
//make a border with 10 bixels width
public Insets insets () {
	return new Insets (10,10,10,10);
}
}

ich denke es ist wahrscheinlich irgendein banaler Fehler und ich sehe den Wald vor lauter Bäumen nicht mehr...

Vielen dank für die Hilfe Ego

 

[Gonzo17]

Du solltest auf jeden Fall Klassennamen groß schreiben. Sowohl eine Klasse, wie auch ein Feld in der Klasse "board" zu nennen, ist ganz schön übel.. (auch wenn das dein Problem nicht lösen wird)

 

[parabool]

startest es wahrscheinlich nicht als Applet.
Bei Eclipse: "Run As Java Applet"

 

[Ego_Akkarin]

Ich bin mir Netbeans gewohnt....
ich habe die Option: "Run As Java Applet" nicht zur verfügung in eclipse....

 

[parabool]

package fehlt und es wird ja die compilierte Datei gebraucht also class

So: chess.ChessPartner.class


nebenbei: wie hast du das bis jetzt getestet?
und (nur kurz) nach welchem Prinzip funktioniert die gegnerische KI?

 

[Ego_Akkarin]

naja gibt noch keine Tests.... ^^

ist auch zumeist aus anderen Code teilen zusammen gestiefelt...
ich habe es jetzt zum laufen gebracht.. in eclipse
