Fair enough :)

Now I was very brief as I'm not 100% sure how the final solution in 
jetspeed looks like.

Ok, our spring configurator includes all files located at a specific 
location and adds all bean definitions found there.
The jetspeed guys enhanced the spring bean configuration format to have
conditionals inside a bean xml definition, so something like (don't 
quote me on the syntax):
<j:if test="database.derby">
   <bean name="database" ...the derby bean
   <bean name="database" ...the hsqldb bean

This allows to have all relevant bean definitions at one single place 
and at runtime it's decided which beans to use.
So this is somthing "on top of the configurator" as this doesn't effect
the current configurator code but is just additional stuff.

But rereading your use case, I assume that you want to skip whole jar 
files, right? So this would be something in the spring configurator of
