Re: How to import classes from a runtime-defined ClassLoader?
There's a lib for this, we've used it in anger, and it seems to work:

Re: How to import classes from a runtime-defined ClassLoader?
I've also had problems passing classes that reside to memory to apache
UIMA or instantiation. What worked for me is this:
(def dynamic-classloader (. (Thread/currentThread)
getContextClassLoader)) (Class/forName mypackage.myclass true
dynamic-classloader)

Yes, sometimes the single-arity version of Class/forName might not be
sufficient = and jim is suggesting, using the 3-arity version helps
then. It's what I'm doing for instance in Counterclockwise (in an OSGi
context).
