Pathname

[Click]

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.

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

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

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