Under Eclipse --> Preferences --> Google --> App Engine I had to point to a copy of the App Engine SDK that I had downloaded and installed locally on my computer as opposed to inside of an IDE. Once I did this the errors about these libs not be in Web-Inf disappeared.

You may just need to clean your project. In eclipse, Project -> Clean.
