upload the class file, instantiate a URLClassloader that points to the
file's url, load the class using that classloader, do whatever you need
using reflection (e.g. instantiate objects, call methods on them, whatever)
and after that dump the classloader.
however as simple as that may be, are you aware of the security
implications of this? if this is not just for playing around, you should
read up on java security and classloading and then subclass URLClassLoader
and implement a very restrictive getPermissions() method for the uploaded code.
before you do that be REALLY, REALLY sure you know what you are doing if
this is for real world use!!!
other than that I don't see any difficulties in achieving what you described.
