[Advanced-java] Origin of a Class

[Mahesh" <maheshg@xxxxxxxxx (Mahesh)]

If given an instance of Object, is there a way to find out the URL from
which it was loaded ?

Object obj = new Object();
You can find the classloader for this object, from
obj.getClass().getClassLoader();
So i can find out whether it was loaded by the system classloader or
URLClassLoader or ...
Can you go further than this ? Is there a way to pinpoint the jar file from
which the class was loaded ?

Also is there a way to find out the "classpath" through JNI ?

thanks
Mahesh
