The ExceptionInInitializerError is the real problem. It means that
there's an uncaught exception in the static{} code in the
DBFactory.java. The problem comes from the TurbineResources not knowing
where to look for the initialization file. so to use the Turbine code,
outside of turbine you have to:
import import org.apache.turbine.util.*; //maybe just TurbineResources
is OK
and then before using turbine code do
TurbineResources.setPropertiesFileName("/path/to/TurbineResources.properties");
Maybe this should be in the FAQ.
