I recently had to downgrade a version of postgres on a devleopment box from 7.3.2 to 7.2.2 to bring it in line with a production server. I reinstalled postgres, postgres-server and postgres-jdbc. Now when I try to run pages from a web application written in JSP using apache/tomcat they don't work. By "don't work" I specifically mean that the 1st page is one where the user's username and password are checked against a table in the database. This is coming back with a logon failed message even though I know that the username and password are correct. So I am assuming that the JSP pages are having trouble connecting to the database. Does anyone know how I can go about debugging this to find the root of the problem? Regards, Phill
