Matt
I am way behind - and I can only offer my support, rather than technical ability.
However, what I have noticed is that the nitpicks although they may seem harsh, gently nudge you in the correct direction. I assume you have received a nitpick from one of the ladies, and I know they will have helped. Did your first attempt actually work? - I assume so, if this is the case, read the nitpick and think....
I would love to be able to help more, and I know you have been through what I am trying to go through, but 4a and 4b take quite a few hours to sort out.
I guess it just gets harder.
Use the instructor's solution from Servlets-4a as your base for this assignment
I assume you have this in mind?
Good luck Matt I am looking out for you.
Regards
Nick
