Yes, but you're always using absolute URLs.
Suppose you want, for example, to have an
"images" directory as a *subdirectory* of the jsp
directory.
You could always write your URLs for <image>
tags as "/jsp/images/xyz.jpg", in which case you don't
have the problem listed above. However, you *do* have
the problem that if you rename your jsp directory to
"myfiles" or somesuch, you have to change *every*
string "/jsp/images/..." to "/myfiles/images/...".
Using relative paths to images would not require any
URL changes when you change directory names,
eg "./images/xyz.jpg" (note leading dot) is still correct
after renaming directory "jsp" to "myfiles". But you
run smack into the problem described above....
