I have a short question about this topic.
I need to unload classes that are dynamically loaded.
I found many examples where classes are dynamically loaded but not unloaded.
Can anyone point me to a good example or tutorial about this topic?

i never came across a situation where I had to unload classes. And is there a way to do it? I am not sure..... And what makes you to unload the classes? Can you be specific abt your requirement? maybe there is a workaround...

To unload a class, first you have to load the class using a ClassLoader you created -- i.e., not the built-in one. Then to unload a class, make sure there are no instances of the class that are reachable, and then dispose of that ClassLoader. The class itself is now eligible for garbage collection.

It is sorta covered in the JavaRanch Style Guide.
