Yeah, it's clear from what's typed below his DB driver is way out of whack with this ancient version of Tomcat.
It probably got updated along the way by network sorts while the Tomcat version stayed put. Go to current, and with current Tomcat, also get a current JDK - I imagine the one you have is ancient as well. -----Original Message----- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: Monday, May 13, 2013 11:16 AM To: Tomcat Users List Subject: Re: Internal Servlet Error -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Jeny, On 5/13/13 2:52 AM, Jeny V wrote: > I'm having some real issues , running programs in Tomcat on my > machine. > > I just copied a jakarta folder named "jakarta-tomcat-3.3.1a" on to my > D: drive (Path : D:\Program Files\jakarta-tomcat-3.3.1a) . I'm going to go ahead and echo the few responses you're already gotten so far and tell you that you really need to discard that version of Tomcat. I don't care if you have an application that "works" on it (obviously in some other environment) and are afraid to upgrade. That version is so old, we don't even have the documentation online anymore for how many unfixed security vulnerabilities may or may not be present in that version. The Java Servlet Specification is nominally backward-compatible, so you should be able to download the latest version of Tomcat, configure it properly, and run your webapp without too many problems. > I can run simple jsp programs with no database connection.

The problem is that you are using a 32-bit ODBC driver on a 64-bit JVM (or maybe a 64-bit ODBC driver on a 32-bit JVM: you didn't specify what kind of JVM you were using, though I suspect you have a 64-bit JVM and a hideously old driver that you've been lugging-around with your Tomcat 3 install). You need to take one of the following actions: 1. Install a 32-bit JVM and use that. This will solve the architecture mismatch by switching the JVM. This may have an impact on your webapp (mostly a smaller maximum heap size) so you may not want to do this. 2. Install a 32-bit version of your ODBC driver and use that. This will solve the architecture mismatch by switching the driver. You may not be able to find a compatible 64-bit driver so you may not be able to do this. 3. Discard your ODBC driver entirely and use a pure-Java JDBC driver. Pretty much every database has one of these things available one way or another. This avoids the architecture mismatch entirely and it will likely result in better performance and stability of your web application. I highly recommend that you take this course of action.

In the future, it would be best to let everyone know what solutions you have tried and what the results were (other than just "it didn't work"). - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJRkRG6AAoJEBzwKT+lPKRYaaoQAJyFeYHGRmZomqFan7W2jdHv u7TZwFKlLAfkMfJaQQibprnuLZpW4flC5gdM0Rbj14EtfDauEMCSfe++oo6YlvqQ F0Mih9ReRt7wSxVLNG58hUqcM6Hg3evEtwWoq9yd5I9YHYdl8Cz0X035/tdUHOUz 2RKBqQbFKr3A8m1k6Q6IYjsRKvPFDwyu0ekRYMrvSdtFZkiYPvzzwW1FpXdQ0Rwh mHmVPrZzoIjiVXLWzT+kfFfrdrK6yBopieYZvOufEei88ZRvaI6u5LrXEpN6GEhX DNkFoDWjPYXuKdQS+JBdwFX16DIKl7nIqI5nZ2sZthjPVqK64+r26R5tp+WEX5rp ADkKyb6iGnwpAxy6l4LBGdanpDug0hC2beeOUtmcQkujJoychlvvF5L69VGpeEU1 JSQR0bQJGJIF9rP/PyAjBLzAUSI9sqh8IUZ+Bm+JrpAgiAWNSmKzeCW2te5r/GcF Nt5ZpKBqMC2UHPNMRxKjIfuGc0gTApX467tVQ5zaouNbWO/lSOMrhZCgF8SD/OcF fiQGrfeCDirHKIR6sczu3r07fGShTNCA47svAFV3/K31ou5dZT6SM3IvVqo2ZXog whHWIXLxGl9SZrJToAJYcjlR2nRSb/yKygiE9Z2csgt34fUj9vQmWFo93ueph+j1 p8A0RhUfe4Kx6KzJ5lmP =LZlk -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
