I doubt that. If I had been designing the system that servlet would not have been called "ExamInitilizer" because that isn't correct spelling. I would have called it "ExamInitializer". Maybe -- as you say -- all the spellings are correct. In which case you too should use the correct spellings.
And by the way you are not trying to "call" a servlet with that code. That is vague and unhelpful terminology. You are trying to forward to a servlet. Please use the standard terminology, it makes it much easier if we don't have to guess at the meaning of vague and undefined words like "call".
