David Jencks wrote a GBean to do mostly what your looking for.  If you look in 
applications/daytrader/derby you'll find how the database is predefined for derby.  In the
plan built in configs/daytrader/src/plan/target/plan.xml you'll find an entry in the deployment
the copies the pre-built database into the Geronimo var directory.

Here is the XML part of the deployment plan.

   <gbean name="DaytraderResources" 
     <!--copies daytrader derby db files into specified location-->
     <attribute name="prefix">META-INF/geronimo-daytrader-derby-db</attribute>
     <attribute name="path">var/derby</attribute>
     <reference name="ServerInfo">

I think this is what your are looking for.  Does this help?
