Hi All,
Finally I could managed to figure out the class loading problem with the
help of Andrus comment. Now we are almost there for Geronimo Cayenne
integration and having a NPE in Cayenne side when I am deploying a sample
given in the Geronimo testsuite. :)
I have given error, Java class file & the persistence xml below. Think it
is due to a one of these given files. Can somebody figure it out directly
& let me know what is there anything missing here? (hope it is not a
problem in Cayenne) :)
BTW as a solution I changed the given lines in EntityMapLoader class, then
it goes bit further and failed in Visitor classes again.
ClassLoader loader = context.getTempClassLoader(); //caynne existing one
ClassLoader loader = persistenceUnit.getClassLoader(); //my soultion since
we need to pass class loader from G side
Does both given lines will give exact same results from Cayenne side?
