Hello, I have been able to fix almost all the warnings and errors. I have to points that I am not able to fix, though: - I was still using DataContext (instead of ObjectContext); is this still a useful class? Otherwise, how do I create a DataContext, as `DataContext.createDataContext();` is not defined - how do I replace the use of ServletUtil.initializeSharedConfiguration?
