If I comment out the jsp:forward, http://localhost:8888/ loads. However http://localhost:8888/employee still returns a 404.

Eclipse and I are not on the best of terms. Frankly, loading JSPs is not something I need to do for how I envision using embedded Tomcat. But I figure I need to know what's happening because if I don't, I'm sure to run into problems down the road when I'm dealing with something more complex. -- "Hell hath no limits, nor is circumscrib'd In one self-place; but where we are is hell, And where hell is, there must we ever be" --Christopher Marlowe, *Doctor Faustus* (v. 111-13)
