Thread: no sound from executable jar file

I wrote a program that uses wav files. It works in Eclipse but when I create an executable jar file the sounds no longer plays.

Any ideas as to what's going on and the fix that is required?

Thanks

Curt

Are there any error messages?
Open a console window, change to the folder with the jar file and enter the command:

java -jar YOURJARFILENAMEHERE.jar

Copy and paste the full contents of the console screen here.

Do all your catch blocks call the printStackTrace() method?
How are you reading the files? If the .wav files are in the jar file you must access them as resources and not as files. Use the getResourceAsStream() method to read "files" in a jar file.

Norm,

Thanks for the reply. There were no errors when I ran java -jar ... It is probably in that I'm reading the wav files as "files" and not using getResourceAsStream. Now I just have to figure out how get that to work with the code I have written.

Thanks

PS...hope you faired well with all the storms. I'll be in Central MO next week. Can't wait to get back to my old stomping grounds.

Do all your catch blocks call the printStackTrace() method?

We're 90 miles from Joplin.
Haven't had any tornadoes here (yet).

Central MO - Rolla?

I placed printStackTrace in all the catch blocks but nothing is being thrown.

Here is the code after I briefly tried to getResourceAsStream working. It was a quick attempt before I got called away.

public class PlaySounds {
 
	private InputStream	fileName = null;
 
/*	public PlaySounds (String fName)
	{
		fileName = fName;
 
		//Thread playFileThread = new Thread (playFileRunnable);
		playFile();
	}
*/	
	public PlaySounds (InputStream fName)
	{
		fileName = fName;
	}
 
 
	public void playFile()
	{
		Runnable playFileRunnable = new Runnable()
		{
			int	EXTERNAL_BUFFER_SIZE = 524288;
 
			// File soundFile = new File(fileName);
 
			public void run()
			{
				AudioInputStream audioInputStream = null;
 
				try
				{
					//audioInputStream = AudioSystem.getAudioInputStream(soundFile);
					audioInputStream = (AudioInputStream) fileName;
				}
				catch (Exception e)
				{
					e.printStackTrace();
				}
 
				AudioFormat format = audioInputStream.getFormat();
				SourceDataLine auLine = null;
 
				DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
 
				try
				{
					auLine = (SourceDataLine) AudioSystem.getLine(info);
					auLine.open(format);
				}
				catch (Exception e)
				{
					e.printStackTrace();
				}
 
				auLine.start();
 
				int nBytesRead = 0;
				byte[] abData = new byte[EXTERNAL_BUFFER_SIZE];
 
				try
				{
					while (nBytesRead != -1)
					{
						nBytesRead = audioInputStream.read(abData, 0, abData.length);
 
						if (nBytesRead >= 0)
						{
							auLine.write(abData, 0, nBytesRead);
						}
					}
				}
				catch (Exception e)
				{
					e.printStackTrace();
				}
				finally
				{
					auLine.drain();
					auLine.close();
				}
 
			}  // public void run()
 
		};  // Runnable playFileRunnable = new Runnable()
 
		Thread playFileThread = new Thread(playFileRunnable);
		playFileThread.start();
 
 
	} // private void playFile()

Here's the calling lines:

InputStream boxingBellIn = getClass().getClassLoader().getResourceAsStream("boxing_bell.wav");
	  PlaySounds playSound = new PlaySounds(boxingBellIn);

I know this line "audioInputStream = (AudioInputStream) fileName;" is incorrect.

Sorry, I don't know anything about using AudioStreams.
If the code worked in the IDE, then the only changes should be to a constructor to use an InputStream vs a File or something like that.

No problem. Thanks for the help.

Okay, I got it working. I found the code at anyexamples.com that reads the file as a stream. It can be found here.

So I created an executable jar that runs and the sound works....on the computer I wrote the code. When I transferred it to a different computer, it doesn't work.

If anyone can help I'd appreciate it. I'm off to search the web to try and figure out this new problem.

Thanks

Curt

How did you test it on your computer? Did you move the jar file to an empty test folder?

To see if there are any errors when running a jar file, open a command prompt window, change directory to the folder holding the jar file and enter:
java -jar YOURJARFILENAMEHERE.jar

Copy the console window and paste here:
To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

I moved it to a completely different computer.

Here is the error I get:

javax.sound.sampled.UnsupportedAudioFileException: could not get audio input str
eam from input file
at javax.sound.sampled.AudioSystem.getAudioInputStrea m(Unknown Source)
at AePlayWave.run(AePlayWave.java:53)

Coincidently, I was getting this error in the IDE but I eventually got it to compile and run without errors. The way I call the wav file is exactly how it is shown in the code from the link in my previous reply (anyexamples.com), which looks like this:

new AePlayWave("boxing_bell.wav").start();

Kevin - not a stupid question. That was the first thing that I checked and the wav files were in the jar file.

Thanks for the replies and I appreciate the help on this.

Curt

You can NOT use the File class. You need to use getResourceAsStream() to read 'files' that are in a jar file.
See the end of post #2

Okay..I went to the original computer and moved the jar file into a folder by itself and it didn't work. I then added the wav files to the folder and it worked.

So, then back to the "new" computer I copied the same wav files to the folder with the jar file and it still didn't work. It was until I moved the wav files from the original computer to the new computer did it work. This makes no sense as the wav files on the original computer came from the "new" computer.

So I double checked that the wav files were in the jar and they are there. Even though they are in the jar file do I still have to distribute them as separate files with the jar file? I'm having trouble with the nuances of Java...it just doesn't seem very intuitive.

Thanks

Curt

You can put everything in the jar file. When reading "files" from the jar file, you can NOT use any file classes. You must treat the "files" as resources.

How are you reading the wav files? The examples you've posted use file classes. They will look outside of the jar file.

Whoops, duplicate effort.
