Many thanks to Doug and Seven. The core problem on our Windows machines was that we neglected to put a <Resource-Link> entry in the ROOT.xml in the Documents and Settings\..... directory.
On the Linux servers (running 5.5), we needed to put a <Resource-Link> entry in the Context.xml under META-INF. And, to think we worked for several hours on such a simple problem.
