Although I never use STM I can't say no one ever should. I believe it was
added to the JSDK in version 2.0. If someone didn't feel there was a need
for it, it never would have been added. I can see where it would make things
much simpler if you don't want to worry about synchronization issues. I
guess by now I always write code assuming it will be used in a
multi-threaded environment.
When I first started writing servlets (coming up on two years ago) I didn't
know that one instance could serve several requests so my servlet had
problems when I moved it from servlet runner to a real web server. STM would
have saved me from rewriting some code back then. I don't use it now because
of performance issues. When you use STM all requests going to your servlet
will be synchronized so that only one request may be handled at a time
(unless your servlet runner creates multiple instances of your servlet).
You should definitely take a look at DbConnectionBroker at
http://www.javaexchange.com. It's free and there are examples of using it
with servlets.
