I have a project where I need to do some scheduled JDBC stuff (thus a Java Agent) and it would be great to make use of the already configured relational stuff for the XPages in the application, rather than doing it all separately.

The agents don't have access to the XPages application instance in memory and thus cannot reuse the connections/OSGi drivers.

Now, you can load the JDBC drivers in agents but you won't get access to the connections pool and it will probably perform poorly.
