If you don't close the connection
If you don't close the connection you'll eventually run the database out
of connections. Also an open connection will use memory within the JVM
and build up the memory in use. Another thing to do is to avoid using
strings, use stringbuffers instead. Try to avoid doing things like this:
Hi Pat,
Not closing a database connection should not run you out of memory, unless
