Servlet 3.0 with annotations & tomcat 7

Question

Hey Folks,
I am at my wits end here trying to deploy a servlet with annotations.
I have managed to successfully deploy it without annotations i.e via the web.xml & everything is fine but I get a status 404 when trying to deploy with annotations.
I am running tomcat :
Server version: Apache Tomcat/7.0.12
Server built: Apr 1 2011 06:13:02
Server number: 7.0.12.0
OS Name: Linux
OS Version: 2.6.35-28-generic
Architecture: i386
JVM Version: 1.6.0_20-b02
JVM Vendor: Sun Microsystems Inc.
I followed the spec so I am sure I am doing everything right from a coding point of view, there is no mention of this servlet what so ever in the apps web.xml
WebServlet(urlPatterns={"/HelloServlet3"})
+public class HelloServlet3 extends HttpServlet {+
+@Override+
public void doGet(HttpServletRequest request,
HttpServletResponse response)
+...+
+}+
The compiled class file (wihin package moreservlets) is located in the following directory
*~/tomcat/apache-tomcat-7.0.12/webapps/onjava/WEB-INF/classes/moreservlets*
The application onjava is mapped in the server.xml
view plaincopy to clipboardprint?
+<Context path="/onjava" docBase="/home/rob/tomcat/apache-tomcat-7.0.12/webapps/onjava" debug="0" reloadable="true" />+
This application has both annotated servlets which don't work & regular servlets with web.xml which do work, can I mix both for onjava above?
Any help greatly appreciated
Thanks
Rob

Apologies for that, but I sent that thread a few days ago on javaranch but got no reply so I thought I would try this site, I intend to post the solution to both forums.
Yes that was the issue I changed to the 3.0 version as specified below & all worked well
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
& it worked, thanks for your help!
