extracting from a jar file

[Dave Jones]

Hello all !!
I need to read some data from a file that is in a jar form.
until now, I used :

 
InputStream inputStream = this.getClass().getResourceAsStream("/something.txt");
        BufferedReader bufferedReader = null;
        String version = null;
        try
        {
            bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            version = bufferedReader.readLine();
        }
(catch (IOException exception)
        {
            System.out.println( "Exception occured when trying to read uploader version ");
        }
 

and it worked just fine, BUT , this works only if I am running it from the jar itself !, I now need to read from a different Jar !, can someone give me a hand here ? this is supposed to be simple, I don't really know why I got tangled up with this ....

Thanks in advance, Dave

Dave,

Check out java.util.jar
package. The classes JarFile, and JarEntry is what you need. You should be able to find a fair few examples too, if you google for it.

HTH.

Probably using the ClassLoader to load the resource will solve the problem. It doesn't matter as long as the resource is in the classpath.

If you just want to read property files or images, you might want to consider ResourceBundle or Property classes, which can read anything present in the classpath (even if from another JAR file).
