Error while deploying in web.xml with web-app_2_5.xsd

Question

Weblogic version 10.3.5 and java is 1.6.0_31
context root is - "/" (slash)
Web.xml - old
has following declaration and works fine
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
i am trying to change web.xml's web-app definition as below
Web.xml - new
<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_2_5.xsd"
     version="2.5">
and to accommodate above change i enclosed all "tag libs" inside <jsp-config> tag which is as per 2.5
when i try to deploy with above changes, i am getting following error but with old definition i am not getting any error.
<Error> <Deployer> <clbblr-4423> <StoreFront> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1358234763292> <BEA-149205> <Failed to initialize the application 'shopstr' due to error weblogic.application.ModuleException: Failed to load webapp: '/'.
