How to migrate for Tomcat 3.3.1 to Tomcat 4.x?
Have I been living under a rock or something?
Does anybody know of information for migrating a Tomcat 3.3.1 web application to Tomcat 4.x and up. I have had Tomcat 4.0 able to start in the past and had the logon screen loaded but after logging in an exception is thrown for the next page. Both pages are jsp's.
What is needed to have the web application working under Tomcat 4.x and if anything what needs to be changed. I know that the Servlet and JSP specifications have changed regarding the web.xml, which has to have all elements in the correct order and the most of the elements for taglib tld files now have '-' in them.
Is their something quite important I have missed or forgotten about, it's sure not a simple task of copying the web application from one tomcat to another.

Nathan,
The Tomcat homepage says that "Version 4.0 implements the final released
versions of the Servlet 2.3 and JSP 1.2 specifications. As required by the
specifications, Tomcat 4.0 also supports web applications built for the
Servlet 2.2 and JSP 1.1 specifications with no changes."
So it looks like 4.0 will support your webapps. Check out the new server.xml
and the docs.
You can read the specs here:
http://jcp.org/aboutJava/communityprocess/first/jsr053/index.html
A check of bugzilla for any outstanding or serious bugs against the version
of Tomcat 4 you are thinking of migrating to would be helpful.
Beyond that, your best bet would be to download it and see what breaks when
you move your webapps to the development environment.
Regards,
Michael

Nathan,
The 4.x spec says it will support Servlet 2.2, JSP 1.1 w/o modification.
Work with a Tomcat 4.x test page to make sure everything works before
trying to debug your app. Also, can you turn off HTML in your emails.
Thx,
Andrew
