How to get the running jar path?

[Jean-Yves Tinevez]

Hi all!

I am trying very hard to get the jar path of the currently running application. Simply because i have a resource folder that i would like to distribute along with the jar itself. (It couldn't work to put these resources directly *in* the jar, for it is a folder that must be listed and edited and modified by the user).

As i would like to distribute the jar, i would like to specify the path to this folder in a kind of robust manner, for example, try to say to the class: "look for where the jar is, the folder should be there".

But i couldn't find a proper way to do it. For example, if i specify

 private final URL parametersRootDirectoryName =  getClass().getResource("/Parameters"); 

i get the path of something *inside* the jar....

Any idea how to do that nicely?

By the way, how do you manage with this kind of deployment issue?

Hi -

Have you considered querying "user.dir" or "java.class.path"? For example:

String mydir = System.getProperty ("user.dir");

Here are a few links that might help:

Yes, I have tried. "user.dir" only gives the directory from where the application was launched, not the one where it lives.
"java.class.path" gives me all kind of path...

Thank you anyway. I have looked deeply on the internet and couldn't find a concise answer....
