Hello all,

I would like, in my Java application, to find the pathname to the .jar file
running. I could not find how to do that in the doc. Can anyone help me?

Thanks, Francois

>find the pathname to the .jar file running.

Get the ClassLoader object of the class containing the main
method of the application,

use getSystemResource( classPath ) of this ClassLoader object,
to get an URL object (where »classPath« might look like
"package/ClassName.class"),

use openConnection() to get a java.net.JarURLConnection object
from this and then

use getJarFile() to get a java.util.jar.JarFile object.

PS: Where classPath is the class containing
the application's main method.

YourMain.class.getProtectionDomain().getCodeSource().getLocation();

It may have achieved the strategy, but what was the goal?
*Why* did you need this location?
