Question

My code runs inside a JAR file, say foo.jar, and I need to know, in the code, in which folder the running foo.jar is.

So, if foo.jar is in C:\FOO\, I want to get that path no matter what my current working directory is.

Answer 1

return new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation()     .toURI()).getPath(); 

Replace ‘MyClass’ with the name of your class.

Obviously, this will do odd things if your class was loaded from a non-file location.
