About Question enthuware.jwpv6.2.641 :

I'm partially agree with the response, but I think in most of the cases you will have javax.servlet.ServletRegistration.Dynamic obtained via ServletContext, on this interface you have method for configure async support, as this interface implements Registration.Dynamic interface.

So I think javax.servlet.Registration.Dynamic and javax.servlet.ServletRegistration.Dynamic are valid, also if you are talking about configure async support on servlet, ServletRegistration.Dynamic looks like better option. Just my comment. XD

The setAsyncSupported method is declared in Registration.Dynamic so this is the only required interface for this purpose. Yes, ServletRegistration.Dynamic can also be used but not required.

javax.servlet.ServletRegistration extends javax.servlet.Registration: Provides addMapping and addMappings
All Known Subinterfaces: ServletRegistration.Dynamic

Looks like the above explanation provided is wrong.
I don't find any addMappings() for javax.servlet.ServletRegistration Interface.

Below is what I found (ref: http://docs.oracle.com/javaee/6/api/jav ... ation.html)
==================================================================
addMapping(java.lang.String... urlPatterns)
getMappings()
getRunAsRole()

Can you please confirm.

You are right, it should be getMappings. Fixed.
thank you for your feedback!
