Desc. Resource Path Location Type Build path is incompete

hi newb here

I am working with myEclipse for the first time trying to scaffold a simple flex applicaton with an oracle back end.
every thing seem to go well until the wizard finishes and i get this message in my error log

Description Resource Path Location Type Build path is incomplete. Cannot find class file for javax/servlet/http/HttpServletRequest

its in my generated file called generated-web-context.xml
trying to find these libs or their references to javax/servlet/http/HttpServletRequest:
org.skyway.spring.util.web.binary.ModelBindingMultipartResolver
org.skyway.spring.util.web.binary.ModelAttributeStreamer
org.springframework.web.servlet.view.BeanNameViewResolver
org.springframework.web.servlet.view.UrlBasedViewResolver
org.skyway.spring.util.viewresolution.UserAgentViewResolver

i have searched google and found nothing on this. i realize i must be missng a library some where but every thing i checked seems to be where it should be

i am On a Windows XP system

What am i doing wrong?

TIA
