classes lib web.xml
Move WEB-INF/classes/lib/web.xml to WEB-INF/web.xml.
Have you configured <welcome-file> list in web.xml. If not, then you need to give full path of file you want to access. Something like this,
http://localhost:8080/MyApp/Greet/index.html If you have MyApp/Greet/index.html in webapps directory of
tomcat.
