One possible approach to this issue is to have a plugin interface which allows users to define new classloaders the same way new functions are added. This is particularly useful in the case of IDE, where a user starts up Eclipse and it loads the state of the last project.
In a dynamic environment where the object model is defined by Schema/XMI/RelaxNG, having the ability to plugin new classloaders would be a useful feature. The reason I say this is, a person could define a new data model with schema and use jaxb/castor to compile it. A new class could be added to jess without having to instantiate a new jess.Rete instance.

This could be done easily enough for specific classes by trying to
load them, but for packages, I'm not so sure. A Java compiler controls
its own classloader, so it knows where classes can be found; that
classloader can search its classpath for a package. But Jess has to
live embedded inside other software, and follow the rules of whatever
environment it's in -- i.e., it doesn't and can't have its own
classloader, so it really doesn't know where to look for packages.
As usual, suggestions welcome.
