I have recently written my first servlet that connects to a database to retrieve
information which is then e-mailed to a number of different addresses.
I ran it successfully on Servlet Runner and then transferred the program to JRun. I
have noticed a problem where the servlet runs seven times, although I am only running
it once, hence creating seven connections to my interbase database.
I have found that the problem comes from implementing the single-thread model, in that
the problem disappears when the single-thread model is not implemented.
If anybody knows why this is - and can offer me any advice on what to do next - I
would greatly appreciate your help - either on how to correctly use the single-thread
model, or how to make my servlet thread-safe - it will hopefully be accessed by a
large number of people at any time!
I appreciate your time and thank you in advance
Daniel Branch
