Tomcat (as far as I know) doesn't use the registry settings. The service side of things probably would, but tomcat should be looking at it's config files.
Check your oracle driver version, you want to make sure that you're either on the "current" driver for your version of the database, or the latest driver. Either or, doesn't matter to much either way. Another thing I've seen is when working with servlets and dispatching to a jsp that the url for the dispatch which works on one server may not work on another. You could be barking up the wrong tree with the result set, even though the error says that it's the line with the result set. I've had a couple of times where the line number from the error didn't exactly match up with the line that it should have been. I usually find that it's helpful to put in debug output when I'm seriously stumped. --mikej -=------ mike jackson [EMAIL PROTECTED] > -----Original Message----- > From: Jose Euclides da Silva Junior - DATAPREVRJ > [mailto:[EMAIL PROTECTED] > Sent: Tuesday, October 21, 2003 12:40 PM > To: 'Tomcat Users List'; '[EMAIL PROTECTED]'; > '[EMAIL PROTECTED]' > Subject: RES: Bugs and weakness when Tomcat works a NT Service (tcservcfg) > > Dear Chuck and friends, > here is all steps taken: > 1 - disable old tomcat's service > 2 - download new tomcat 4.1.17 > 3 - install it as a NT service > 4 - process of app configuration ( server.xml, web.xml and adding folders ) > AGAIN, the old big problem still alive: only the static pages are > availables, so whenever my app tries to use ResultSet, I get that known > error message: > > HTTP Status 500 - > > type Exception report > > message > > description The server encountered an internal error () that prevented > it from fulfilling this request. > > exception > > java.lang.NullPointerException > at BancoServlet.recuperaTopicoAssunto(BancoServlet.java:413) > > Really, what is wrong with this procedure?
