    For this particular small project, I desired to implement
everything as JSP pages.  This was a tactical decision for
the purpose of simplicity (i.e. follow one paradigm).  There
was "some" duplication of code, but not much.   Overall,
I was pretty happy with the decision.   The only part I'm
having trouble with is the serving up of a binary image
retrieved from a database.  I used the example out of the
Oreilly Servlet book.   It work great, except for this
stream closure problem.  Another post has explained 
the paradigm problem, and that I should attempt this
in a servlet only.

    Funny, until now, I was thinking a JSP files seemed to
do just about everything a servlet could do.
