I have existing web-app which I want to convert into web.xml-less of servlet's 3.0. I've managed to make it working, however there are 2 tags in web.xml which I still don't know the equivalent code in web.xml-less environment.

<welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
</welcome-file-list>

<error-page>
    <error-code>404</error-code>
    <location>/pageNotFound</location>
</error-page>

Any help is appreciated

java tomcat7 java-ee-6 servlet-3.0
