There is an example system-database-plan.xml that defines a DataSource 
for accessing the embedded Derby database. This uses the generic JDBC 
connector from TranQL and can be adapted to other vendor's drivers as 
needed. You use the same RAR file, just different deployment plans.

To access from a web app you need a <resource-ref> not a 
<resource-env-ref> - the Jetty plan looks like:



where <target-name> is the name of your datasource.

If you don't want an additional RAR config, I think you can actually 
embed its plan inside your geronimo-jetty.xml definition. Basically copy 
the <resource> element from the RAR plan and put it at the end of your 
web-app element (I know this works for app-clients).
