getting the name of a jar from inside the jar



I have a jar. This jar has code in it similar to this:
 
========================================================
JarFile studyJar = new JarFile(studyID+"."+studyVersion+".jar");
Enumeration enum = studyJar.entries();
========================================================
 
 
studyJar is a JarFile representation of the jar this code is executing in. I get studyID and studyVersion from a text file located inside the jar.
 
I need to add the functionality where the jar can be renamed by end users.
 
Is it possible for code inside of a jar to get the name of the jar it resides in? I need its name to instantiate the JarFile above.
 
Thanks,
 
-Jason
