Including Recources into a runnable JAR using eclipse

[Lucas_F98]

OK, so i have a .wav audio file and i am using eclipse. I have imported it into the src folder, and am calling on it in the code using "src/blah.wav".
It works when i run it in eclipse but if i export is a s a runnable JAR and try to use it it doesn't.
Is there something i have to do to make it get included in the jar file, i selected "package required libraries into generated JAR" if that helps.
i am new to java so any help would be appreciated

Select the project you want to export, right mouse click and select Export ... > Jar file; deselect everything in the right pane (you don't want Eclipse's crap in your .jar file) and select your resources in your left pane (including all the packages with the code in it). Follow the other steps in the wizard and you're in business.

kind regards,

Jos

Whilst that might work a batch file is needed to launch it. What i am looking for is a way to make a runnable JAR File. ie. double click to run.

Thanks,

Also you'll probably have to change your code as the .wav will no longer be a file on the file system, but a resource in your jar.
SO you'll need getResourceAsStream (or similar) to access it.

CODE:

import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class sound {

    
    public static void warningsound() {
         try{
                AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("src/SEWS.wav").getAbsoluteFile());
                Clip clip = AudioSystem.getClip();
                clip.open(audioInputStream);
                clip.start();
            }catch(Exception ex){
                
                ex.printStackTrace();
            }
    }
}

i want to export this as a Runnable JAR File so how would i include the "getResourceAsStream" thingo you said.

Sorry for me not knowing much,

Lucas

That is one of the following steps of the wizard: it asks you to specify a file to be used as the 'manifest' entry; that entry specifies the Main-Class in your .jar file. Read the relevant documentation for details.

Cool That works with a double click, but the audio does not play. Tolls Said i will need "getResourceAsStream" how would i do that

cheers,

[Tolls]

Please use code tags when posting code:

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("src/SEWS.wav").getAbsoluteFile());

That is getting a file from the file system, which will not work with a resource in the jar.
There is a method called getResourceAsStream() that handles that problem:

InputStream is = <whatever class you're in>.class.getResourceAsStream("<path>");

Exactly what path you need you'll have to muck about with, as I can never remember. I think "/SEWS.wav" will look for the file at the top of the jar.

[Lucas_F98]

So do i put

InputStream is = <whatever class you're in>.class.getResourceAsStream("<path>");

inside

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("src/SEWS.wav").getAbsoluteFile());

like:

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("InputStream is = <whatever class you're in>.class.getResourceAsStream("<path>")").getAbsoluteFile());

or

InputStream is = <whatever class you're in>.class.getResourceAsStream("<path>");
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File("is").getAbsoluteFile());

(would "is" need quotes?)

Cheers

[Tolls]

It's an InputStream.
getAudioInputStream() takes an InputStream.
Put it straight into there.

[Lucas_F98]

OK That just went over my head, here is my code can you fix it up, because i am as confused as a legless spider at the moment.

Thanks,
Lucas

package fire;

import java.io.File;
import java.io.InputStream;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class sound {
	
InputStream is = sound.class.getResourceAsStream("/SEWS.wav");
	
	public static void warningsound() {
		 try{
			 
					 AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(is).getAbsoluteFile());
		       
		        Clip clip = AudioSystem.getClip();
		        clip.open(audioInputStream);
		        clip.start();
		    }catch(Exception ex){
		        
		        ex.printStackTrace();
		    }
	}
}

Look at the API for (one version of) the method you are using.

[Lucas_F98]

Thanks Tolls,

I am having a real mental blank at the moment and cant seem to figure it out could you please just tell me what i should replace this line with

 AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(is).getAbsoluteFile());

Cheers, much appreciated,

Lucas

1. Don't PM people with your urgency. Most of us here have jobs to do and only come on when we have a window of opportunity.
2. Learn to read the API. I gave a link to the specific bit that you need to use. If you can't understand it then you probably need to take a step back from messing with audio and learn how methods are called in Java.

[Lucas_F98]

Hello Tolls,
I am sincerely sorry about doing that and i will never do it again,
And i did read the API but as i am a beginner i did not understand it, from what i believe from reading the API is that i should use this code

package fire;

import java.io.InputStream;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class sound {
	
	public static  void warningsound() {
		 try{
			 InputStream is = this.class.getResourceAsStream("SEWS.wav");                    //"this" is in this line
			 AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(is);
		       
		        Clip clip = AudioSystem.getClip();
		        clip.open(audioInputStream);
		        clip.start();
		    }catch(Exception ex){
		       ex.printStackTrace();
		    }
	}

}

It says that "this" can not be used in a static context so i was wondering what i should replace it with

my wav file is "SEWS.wav" in the pic

so what would i use to reference to it would it be "/src/SEWS.wav" or what, i have no idea

Cheers, and Sorry,
Lucas

[Tolls]

As per my post: "whatever class you're in".
In your case sound (which should be Sound by the Java naming standards).
"this" references the current object, which does not exist in a static method, hence the error.

Cheers,

All fixed, Thanks Tolls And JosAH
