    Default Need help with IllegalStateException

    Hello everybody,

    I am currently building a fairly simple soundboard as a surprise for a friend. I got it that far, that the sounds play according to the button pressed. However I do have two major problems:

    1. When I play a sound and press another button after and/or while playing back the first sound, I get an IllegalStateException and the program crashes.

    2. I currently access the sound files (waves) using the absolute paths and I cannot find a solution to get those files working from an executable jar file.

    I have read many threads here and in other forums already but I cannot get this solved. Please help me! Any tip is highly appreciated. Thanks a lot!

    Here is the current code:

    Java Code: 
    package fun;

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.URL;

import javax.swing.*;

class GUI extends JFrame implements ActionListener {

	final InputStream in = GUI.class.getResourceAsStream("./META-INF/sound/1.wav");
	
	File  sound1 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/1.wav" );
	File  sound2 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/2.wav" );
	File  sound3 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/3.wav" );
	File  sound4 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/4.wav" );
	File  sound5 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/5.wav" );
	File  sound6 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/6.wav" );
	File  sound7 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/7.wav" );
	File  sound8 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/8.wav" );
	File  sound9 = new File (  "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/9.wav" );
	File sound10 = new File ( "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/10.wav" );
	File sound99 = new File ( "/home/noneofthem/Dropbox/workspace/Mike/META-INF/sound/99.wav" );
	
	public GUI () {
	
		super ( "MikeBoard 1.0" );
		this.setDefaultCloseOperation ( JFrame.EXIT_ON_CLOSE );
		this.setSize ( new Dimension ( 710, 140 ) );
		this.setLocationRelativeTo ( null );
		
		Font mainFont = new Font ( "Verdana", 1, 14 );
		
		JPanel mainPanel = new JPanel();
		mainPanel.setBackground ( Color.getHSBColor ( 255, 153, 51 ) );
		mainPanel.setLayout ( new FlowLayout ( FlowLayout.CENTER ) );
		
		final JButton button1  = new JButton (  "Keine Zeit" );
		final JButton button2  = new JButton (   "Bis 7 Uhr" );
		final JButton button3  = new JButton ( "Und dann..." );

		final JButton button9  = new JButton ( "Die anderen" );
		final JButton button10 = new JButton ( "Hilfe holen" );
		
		JButton[] buttonArray = new JButton[] {
			
			button1,
			button2,
			button3,
			button4,
			button5,
			button6,
			button7,
			button8,
			button9,
			button10,
		};
		
		for ( JButton button : buttonArray ) {
			
			button.setFont ( mainFont );
			button.setBackground ( Color.getHSBColor ( 255, 255, 204 ) );
			button.setForeground ( Color.WHITE);
			button.setPreferredSize ( new Dimension ( 135, 50 ) );
			button.addActionListener ( this );
			mainPanel.add ( button );
		}
		
		JPanel mainBox = new JPanel();
		mainBox.setLayout ( new BoxLayout ( mainBox, BoxLayout.Y_AXIS ) );
		mainBox.add ( mainPanel );
		
		this.add ( mainBox );
		this.setResizable ( false );
		this.setVisible ( true );
	
	} // END of GUI constructor
	
	public void actionPerformed ( ActionEvent e ) {
		if ( e.getActionCommand().equalsIgnoreCase ( "keine zeit" ) ) {
				playSound ( sound1 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "bis 7 uhr" ) ) {
				playSound ( sound2 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "und dann..." ) ) {
				playSound ( sound3 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "kaffee" ) ) {
				playSound ( sound4 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "er ist froh" ) ) {
				playSound ( sound5 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "isolation" ) ) {
				playSound ( sound6 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "probleme" ) ) {
				playSound ( sound7 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "es hilft" ) ) {
				playSound ( sound8 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "die anderen" ) ) {
				playSound ( sound9 );
		} else if ( e.getActionCommand().equalsIgnoreCase ( "hilfe holen" ) ) {
				playSound ( sound10 );
		}
	} // END of actionPerformed

	private synchronized void playSound(File file) {
		
			try {
				AudioClip test = Applet.newAudioClip ( file.toURL() );
				test.play();
			} catch ( Exception e4 ) {
				e4.printStackTrace();
			}
		
	} // END of playSound
} // END of GUI class
    And here is my main:

    Java Code: 
    package fun;

public class MikeBoard {

	public static void main(String[] args) {

		GUI mainGUI = new GUI();
		
	} // END of main
} // END of MikeBoard

    I get an IllegalStateException and the program crashes.
    The stack trace will tell you which line of code threw the exception, and the method calls that led to it. The API for the method that threw the exception will provide further guidance.

    UPDATE:

    I got it working now! The only thing I couldn´t figure out yet is how to access the sound files from within an executable jar file, so I would be grateful for any advise you can give me! Many thanks in advance! :-)

    Here is the updated code:

    UPDATE:

    Everything is working alright now. I had some issues with incorrectly installed Java versions (OpenJDK vs. Sun JDK). After a reinstall of the OpenJDK, Eclipse and Netbeans, everything is working properly.

    Here is the finished code, if anyone needs some code examples:

    Java Code: 
    package mikeboard;

import java.applet.Applet;
import java.applet.AudioClip;
