If you deploy a WAR file and then restart Tomcat, sometimes your context.xml will be copied into either conf/Catalina/localhost or work/somethingorother and it gets cached and not updated for various reasons. When you deploy the WAR file, are you just dropping it into your auto-deployment directory (usually CATALINA_BASE/webapps)? If so, Tomcat may not be triggering the re-load of the context.xml from your WAR file. You might want to try a few things: 1. Shutdown Tomcat and blow-away the entire 'work' directory. Make sure there is no exploded WAR file in your webapps directory. Re-start Tomcat with your WAR in place and make sure it gets auto-deployed. Hopefully this will work. 2. Use the manager application to re-deploy your WAR file. I don't use the manager app for anything, so I don't know if it will auto-update the on-disk, cached context.xml, but it's an easy check. 3. Always use exploded WAR files if all else fails. Honestly, if you can't get WAR files working, you should head back to the list and ask again. I'm sure that other folks have more ideas and understand Tomcat's exact behavior in these situations. > tomcat 5.5.17 This is quite an old version. Are you able to upgrade to a more recent 5.5.x version? I haven't checked the changelog, but it's possible that these types of behaviors have been tweaked since 5.5.17. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkj6o3IACgkQ9CaO5/Lv0PC1SgCggYHM0Hs+q3TAjP9ZMC0AXRPo IjYAoK/kKbMYeGLQcVkITsiwF9vGEWVN =lbRQ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
