cvc-complex-type.2.4a: Expected elements 'servlet-class@http://ift.tt/nSRXKP jsp-file@http://ift.tt/nSRXKP init-param@http://ift.tt/nSRXKP load-on-startup@http://ift.tt/nSRXKP enabled@http://ift.tt/nSRXKP async-supported@http://ift.tt/nSRXKP run-as@http://ift.tt/nSRXKP security-role-ref@http://ift.tt/nSRXKP multipart-config@http://ift.tt/nSRXKP' instead of 'display-name@http://ift.tt/nSRXKP' here in element servlet@http://ift.tt/nSRXKP

I am not using element like init-param in my web.xml, then why we see in above as it is expecting for it.

Please let me know what fix can be added to this above.
