Different browsers do stuff like write HTTP headers in different order, or
with slightly different syntax,
like "content-type:" vs "content-type :". This turned out to be the cause
of a NPE I was seeing only
in the case of a Netscape client accessing a servlet that was running on
top of a Domino server; IE
client to Domino was fine, any client to Apache/Websphere or IIS/Websphere
was fine. Turned out Domino
was not tolerant of the extra space before the ':' char, so it thought no
content-type was in the request,, and
that ultimately resulted in ServletRequest.getContentType() returning null,
which in turned caused the servlet to NPE.
I imagine there's tons of differences like this to contend with. I suggest
you wrap your doGet/doPost implementation
with a try, and in the catch print out a stack trace to the servlet
log. Good luck.
