Thanks, Olu!
OK, everything's working now (kinda)
My problem is that my servlet (sitting in the /classes subdir & accessed via
'http://localhost:8080/servlet/ServletName') cannot get to any servlet in the
'localhost:8080/examples/servlet' context, even though the samples are all there
and can be invoked directly through the browser. Nor, for that matter, can it
get to any of the sample JSP's ('/localhost/examples/jsp/...').
The servlet I create in '/classes' can only access other servlets in the same
subdir, or JSP's lying anywhere below '/webpages'
Has anybody else come across this problem?
I have NOT modified any of the .CFG or .PROPERTIES files
My environment is NT4/JDK2

req.setAttribute("dataBean", bean); //lifespan = page
