Hallo, auch wenn es nicht zum Thema von oben passt...zumindest nicht ganz...habe ich ne Frage.
Habe den JDK installiert und auch Java(TM) ME Platform SDK 3.0.
Danach schrieb ich wie gewohnt mein Programm (was allerdings noch einiges an überarbeitung und verfeinerung braucht)

import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Graphics;

public class ActionCanvas extends Canvas implements Runnable {

int displayWidth;
int displayHeight;

int ballX;
int ballY;
int ballWidth = 10;
int ballYSpeed = 8;
int ballXSpeed = 5;

int schlaegerX;
int schlaegerY;
int schlaegerWidth = 50;
int schlaegerHeight = 5;


int schlaegerXSpeed;

public ActionCanvas() {
setFullScreenMode(true);
displayWidth = this.getWidth();
displayHeight = this.getHeight();

ballX = displayWidth/2-ballWidth/2;
ballY = displayHeight/2-ballWidth/2;

schlaegerX = displayWidth/2-schlaegerWidth/2;
schlaegerY = displayHeight-schlaegerHeight;

new Thread(this).start();

}

protected void paint(Graphics g) {
paintTennisField(g);
paintNet(g);
paintBall(g);
paintSchlaeger(g);
}

void paintTennisField(Graphics g) {
g.setColor(0,255,0);
g.fillRect(0,0,displayWidth,displayHeight);
}

void paintNet(Graphics g) {
g.setColor(255,255,255);
g.fillRect(0,displayHeight/2-3,displayWidth,6);

g.setColor(0,0,0);
g.drawLine(0,displayHeight/2-3,displayWidth,displayHeight/2-3);
g.drawLine(0,displayHeight/2+3,displayWidth,displayHeight/2+3);
}

void paintBall(Graphics g) {
g.setColor(255,255,0);
g.fillArc(ballX, ballY, ballWidth, ballWidth, 0, 360);
g.setColor(220,220,220);
g.drawArc(ballX, ballY, ballWidth, ballWidth, 0, 360);
}
void paintSchlaeger(Graphics g) {
g.setColor(0,0,255);
g.fillRect(schlaegerX, schlaegerY, schlaegerWidth, schlaegerHeight);
}
void moveBall() {
if(ballX <= 0){
ballXSpeed = -ballXSpeed;
}
if(ballY <= 0){
ballYSpeed = -ballYSpeed;
}
if(ballX >= displayWidth - ballWidth ){
ballXSpeed = -ballXSpeed;
}
if(ballY >= displayHeight - ballWidth){
ballYSpeed = -ballYSpeed;
}

ballY = ballY+ballYSpeed;
ballX = ballX+ballXSpeed;
}

protected void keyPressed(int keyCode) {
switch(getGameAction(keyCode)) {
case LEFT: schlaegerXSpeed = -10;
case RIGHT: schlaegerXSpeed = 10;
case UP: /**/;
case DOWN: /**/;
}
}
protected void keyReleased(int keyCode) {
switch(getGameAction(keyCode)) {
case LEFT: schlaegerXSpeed = 0;
break;
case RIGHT: schlaegerXSpeed = 0;
break;
}
}


void moveSchlaeger() {
if(schlaegerX <= 0){
schlaegerXSpeed = -schlaegerXSpeed;
}
if(schlaegerX >= displayWidth - schlaegerWidth ){
schlaegerXSpeed = -schlaegerXSpeed;
}

schlaegerX = schlaegerX+schlaegerXSpeed;
}


public void run() {
while(true) {
moveBall();
moveSchlaeger();
repaint();
sleepSomeTime(25);
}
}

void sleepSomeTime(int time) {
try {
Thread.sleep(time);
} catch (Exception e) {}
}
}

Wenn ich das nun kompillieren will kommt im Output folgendes:

ERROR - Ant is misconfigured and cannot be run.

was hab ich nur wieder falsch gemacht? Das passiert mir andauernd! Meist is es nur ein ganz simpler Klick oder ein Häckchen was ich falsch gesetzt habe..

Danke schonmal falls mir jemand helfen kann!
