Hi,
I need to load Singleton classes multiple times.I want to load them using different classloaders .How can I do it? (Even if I create a custom classloader ,I am not able to obtain different references when I initiate the classloader instances using 'new CustomClassLoader()'.I am delegating the control to the parent ClassLoader class in the loadClass() method for loading the class ). If I get different classloader for a class, will the objects created in the loaded class also will use the same classloader?

Thanks,
Srini

You will get separate classes for each classloader that loads and defines the class, which is not necessarily the classloader on which loadClass() was called. You can check which classloader loaded a class by calling its getClassLoader() method.

The simplest way to load a class multiple times would be to make sure the class is not in your class path, create a new URLClassLoader each time, and use reflection to access the class's fields.
 
Don't get me started about those stupid light bulbs.
