Brian,

Thanks for the response.

By exhaustive search, I've found that hostsrv evidently uses a common root
for everyone, so I have to prefix my contexts and file specs with my user ID

Needs["webmxxxx`myfunc`]

and

Import[ToFileName[{"webmxxxx"}, "myfile.GIF"]].

Relative addressing of *.jsp files from within *.html files needs a

../app1/MSPScripts/webxxxx/myfile.jsp.

Cobbling up my local file structure to make it so the same files will run
both places is a royal PITA.

At least it runs.

Maybe answering my own post will save someone else days of pain.

Thanks again,
Fred
