OpenJPA Exception (An error occurred while parsing the query filter
"SELECT du from org.apache.ode.store.jpa.DeploymentUnitDaoImpl du")
Did anyone have any clue about the cause for following exception when using
ODE + OpenJPA in OSGi environment. Why we are using "SELECT du from
org.apache.ode.store.jpa.DeploymentUnitDaoImpl du" instead of "SELECT du
from DeploymentUnitDaoImpl du"? I have seen the later style in other places
in ODE.

It's probably a class loading issue. For example, say the classloader in
which OpenJPA is loaded is not the same as the one where the DAO creation
actually happens so they don't see the same class. Pick your favorite class
loading headache :) I'd ask on the OpenJPA mailing list, they might have
seen this before and point you to specific things to be careful with when
deploying in OSGi.
Cheers,
