sometimes ago a friend of mine found that some jsp engines will show jsp
source by appending
chars like '/' or %00 (there are more examples).  The cause of that is sun's
java file io package
will open a file even if there are wired stuff appended to the end.  At the
same time the engine
think the requested string is not a jsp because there are things appended to
it.

Since you brought it up I think it is a good time to put it on the mailing
list.

The source of the jsp could be hamfull to be seen if it contains passwords
to database systems
or other such info.  It might be a good idea to use a bean to to that kind
of the stuff and just let
the jsp invoke the bean
