Hello!
I can see same problems I have met almost a year before.
Also have module architecture...
First of all don't use Configuration.initializeSharedConfiguration(
fileConf );
It's not for module applications...
You could use something like this:
Configuration conf = new DefaultConfiguration("module1-cayenne.xml");
conf.initialize(); //mandatory. Means "load and parse my xml".
DataDomain module1Domain = conf.getDomain(); //actually it's a
factory for DataContext based on configuration
DataContext module1Ctx = module1Domain.createDataContext(); //here we
go! we got context for module1
