How to use Servlet 2.4 with Netweaver Developer Studio 7.0?

Hello,

When I define my web.xml as follows:

<!DOCTYPE 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">

I get an error in french: "La DTD du type de lélément racine "" doit se terminer par '>'." Saying that the DTD of type of root element must end with '>'     

How can I solve this error?

Thanks for your help,
