I walked through all the steps to create a web project following along with the tutorial. When I get to deploy the application, Tomcat throws the following exception:

Nov 12, 2004 2:02:11 PM org.apache.commons.digester.Digester error

There are compiler errors according to the editor in web.xml also. The web.xml file:

<?xml version=”1.0″ encoding=”UTF-8″?>

The problem is that you specified that you wanted a J2EE 1.4 project and Tomcat only supports J2EE 1.3. The web.xml is perfectly valid for a container that supports it. To correct the issue, simply recreate a J2EE 1.3 web project and use that instead. For additional information on web projects, please see the Web Project quickstart in the Documentation section of the website.

Just a clarification, this won’t work with Tomcat 4, but should work fine with Tomcat 5 (supports Web 2.4 spec)

That solved it, thanks.
