As long as your web apps are spec-compliant to the servlet 2.2 and JSP 1.1
specs, and don't rely on bugs or other non-spec behavior in 3.2.3, they
should indeed work. Failure to do so is a bug in Tomcat 4.
The most likely causes for problems:
* Your web.xml has elements not in the order required by the
DTD. Tomcat 3.2.3 accepted them anyway (even though it allowed
non-portable apps). Tomcat 4.0 uses a validating XML parser,
so your web.xml elements MUST match the required order.
* Assumptions about the current working directory when running
Tomcat. This is never portable, and you should design your
applications not to rely on it.
* Differences in the global class loading architectures.
You'll need to be more explicit about what your WAR file
does, and how it fails, to see if this is your issue.
