To help you, we would need to know a)  if you can run a very simple jsp
test to ensure that database connectivity is occuring (i.e. can you pull
and display a record) and b) if you are using an cryptography (like MD5)
in your password checks.

You can set the debug level up on PostgreSQL.  This is done by modifying
the startup script.
