Note that we see the following in standout log:
Line 4 Column 20 -- cvc-complex-type.2.4.a: Invalid content was found starting with element 'servlet-class'. One of '{"http://java.sun.com/xml/ns/javaee":description, "http://java.sun.com/xml/ns/javaee":display-name, "http://java.sun.com/xml/ns/javaee":icon, "http://java.sun.com/xml/ns/javaee":servlet-name}' is expected."

This is due to <servlet-name> is not iLine 4 Column 16 -- cvc-complex-type.2.4.a: Invalid content was found starting with element 'servlet-class'.

n web.xml.

This is due to missing <servlet-name> in web.xml.
This is the limitation of the test as <servlet-name> is going to be specified
