About Question enthuware.jwpv6.2.942 :

[ETS User]

A JSP file cannot be used in a <servlet-mapping> tag. Isn't this correct?

<servlet-mapping>
<jsp-file>/requestInfo.jsp</jsp-file> <!-- this isn't right, right? -->
<url-pattern>*.a</url-pattern>
</servlet-mapping>

[admin]

This statement as such is correct but the code shown in the question doesn't contain this error and that is why this is not a correct option. But I agree that this option does not make much sense and should be removed.

HTH,
Paul.
