this is due to the fact that the servlet 2.3 spec enforces the order of elements in web.xml. Make sure they appear in the order given by the error and it should be fine.

A separate application I have however, which runs fine under Tomcat v3.3, is having troubles starting up under Tomcat v4. Are there any upgrading to Tomcat 4 (from Tomcat 3.3) guidelines which exist which one needs to follow? Changes required to web.xml file for example? The specific problem I see is described below. thanks in advance Greg PS Just joined the mailing list.
