Dynamic program calls/run-time class names

In traditional languages calling a run-time module is a natural feature. For
instance,

               CALL    PROG

RPG statement calls a program whose name is unknown at compilation time.
In Java a similar "dynamic" call is supported by RMI, but the performance
penalty seems to be too high, especially if running a just simple servlet
model. There is also Dynamic Invocation Interface, which is basically the
same thing.

Is there a better way? What I need is a preferably nice and simple way of
invoking methods unknown at compilation time. It can also be assumed that at
compilation time I'm not aware of the class names either. What is the most
common way of doing this?
