dynamic type invocation in applets across jars

[Jonathan Shore]

I have not been able to determine a solution to the following problem:

- have an applet sourced from two jars (a.jar, b.jar)
- one a class in one jar attempts to instantiate a type dynamically in
other jar
- "a" has infrastructural classes and "b" has application classes.
"b" depends on "a", but "a" has machinery to instantiate a class in
"b".
- the applet tag lists the jars as: archive='a.jar,b.jar'

In an object created from a class in a.jar:

class.forName(<typename in jar b>)

fails with a ClassNotFoundException. I think this the problem is that
classes in a.jar are using a class loader that does not have top-level
access to the "a" and "b" jars.

I can't get access to the system class loader as am in a privileged
environment. Any thoughts on how to solve this?

Thanks

Are both jars in the same directory (and on the same server of course)?
This is the only way it works.
