Question

My Spring application runs on Tomcat 6.0 on localhost.

When I try to run it on 5.5, I get an error “Tomcat version 5.5 only supports J2EE 1.2, 1.3, and 1.4 Web modules”.

How do I know the type of Web module my app is running on, and how do I make it run on 1.4?

Thanks.

You need to use the correct J2EE version (<1.5) of your dependencies for your development.

You also need define a compatible servlet version to use in web.xml, i.e.

<web-app version="2.4" 
     xmlns="http://java.sun.com/xml/ns/j2ee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
                         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
