If you open the webapp project's Properties dialog and go to the
Deployment Assembly page, do you see the dependent projects listed
there? If so, what are the Deploy Path and Source for these?

Dependencies in a webapp project on other "utility" projects are assumed
to be "jar like" dependencies. The output artifacts from the Java
source folders are "assembled" into a jar and placed in the published
webapp's WEB-INF/lib. As long as maven isn't building into it's version
of the jar resources that WTP isn't aware of, the jar WTP "assembles"
should be fine.
Cheers,
Larry
