Upgrade Tomcat 4.1.18 to 4.1.39
Hi,
I am new to Tomcat. We have an application written in 4.1.18. At a minimum
I would like to upgrade to version 4.1.39. The application runs on Windows
2000 sp4.
Is there an upgrade exe that can be run? Or, could you point me to a good
page that would walk me through the process? Both?
Also,
Idealy I would like to upgrade to the most recent Tomcat Version 6.1. I
assume that would be difficult as different jsp versions may cause issues.
Thoughts.
Thank you very much
Jim

I would think that effort would border on the trivial - but I've never run a Tomcat that old.

Install the new one in a different directory, and compare all the .xml files between the two. Modify the 4.1.39 ones as needed.

This is for 5.5 to 6.0 (there is no 6.1), but it's a start:

That won't be a problem, since the WEB-INF/web.xml carries the spec version the servlets are written against, as should the individual .jsp files. It's primarily the Tomcat-specific configs that have to change.

Unfortunately, there are no automated upgrades that you can run.

JSP is relatively backward-compatible. I would forget about moving from
4.1.18 -> 4.1.39 and go directly to 6.0.18 (there is no production 6.1
version of TC yet).
My best advice is to start with a stock server.xml from your new version
and merge-in configuration changes manually. Remember a few things:
1. <Context> elements now belong in your webapp's META-INF/context.xml
2. JNDI resources that don't need to be shared among webapps should
be defined within your <Context> instead of in server.xml
3. There is no such thing as <Logger> anymore in server.xml
See the following references for more information:
http://tomcat.apache.org/tomcat-6.0-doc/config/context.html
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
Any complaints about TC's logging system should be directed to André
Warnier. He's our resident logging-system complaint file clerk. ;)
