I am creating a client - server application that will process lines like:

startjob
adduser
adduser
adduser
adduser
endjob

adduser can be an unlimited amount of times. I want to process the
lines as they come into the Servlet, that way a seperate process could
be doing something to complete each of the tasks, while I am in the
process of working on reading the lines.

I have written a Socket server of my own to do this before, I am now
trying to use Tomcat Servlet to do the same thing, because Tomcat
already some behind the scenes stuff already setup.

Does this make sense? Am I totally off my rocker? (My wife would
definately agree with that last bit.)
