Tomcat Upgrade (to 4.1.24) Successful!

I spent the last 5 minutes upgrading this site to Tomcat 4.1.24. It was pretty simple; here's what I did:

  • Copied conf/tomcat-users.xml and conf/server.xml from old version to new version.
  • Copied JDBC Drivers from common/lib.
  • Moved relevant apps from webapps/ to new version.

The manager application looks like it has been improved to allow for easier deployment. It now offers you more, clearer choices and you don't have to remember the cryptic syntax for deploying a .war file. Now it's just browse and submit. Let me know if you see any issues.

Update: I still can't get the "admin" application to work, but I never use it, so not a big deal. It hasn't work on past versions of Tomcat either. Currently, it gives me the following error:

HTTP Status 503 - Servlet action is currently unavailable

I had the same problems until I realized that the tomcat-users.xml needs a user with a role of "admin" to allow you to log in via the admin application. It is pretty nice. 4.1.24 is the first I have been able to get it to work.

My tomcat-users.xml file <em>does</em> have a user with an "admin" role - it's the application that has problems. I am able to login just fine, but when I try to do anything, it gives me the error I specified. Like I mentioned, it's not a big deal, so I'm not too worried about it.

Strange, it works fine for me in the 18 version. Check the admin.xml file and make sure it is ok. Maybe a MacOS specific problem. Linux and Win2k are no prob for me.
