Can I dynamically unload and reload (other versions of the same) JAR?

Question

I am writing a server program which is used to run unit tests of an API (displaying lots of information and providing web access to control / monitor the whole thing)...<

You can use the opensource package : JclLoader which helps in loading different versions of the same jar. This was also a need in one of our systems to do testing .
