Exist SoftwarelabsHi,
We have an application that makes use of jetspeed (with turbine and torque) and
we would want to integrate it with Derby(embedded) Database. We've downloaded
and build the branch in torque(TORQUE_3_1_BRANCH) that supports derby.
Generated and deployed the 3 jars in maven : torque-3.1.2-dev.jar,
torque-gen-3.1.2-dev.jar and maven-torque-plugin-3.1.2-dev.jar. After
generating the OM files, We've deployed the application in Tomcat. But when we
access the application, we get an java.lang.InstantiationException exception
in the log file and Null pointer exception in the console. We checked the
derby.log file and there is no error thrown. Below are the stack trace we get :
in the log file :

We thought that we might be missing out on something. We would appreciate your
ideas on these.
TIA
