java servlet version

[azuniga]

I'm currently using smartgwt power 3.0 with gwt 2.3 on redhat linux. I will be deploying to weblogic 12c. Every version of the web.xml file that I have seen from the enterprise showcase uses java servlet version 2.4.

<web-app 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"  
    version="2.4">

Can I replace 2.4 with 3.0? Will this work? What would I have to do to use 3.0?

You can replace it with 3.0 - servlets 3.0 is backwards compatible.

Alright, thank you.
