I just tried a similar 'jspc' command and it generates
all <jsp>.java under the same output directory - there
is no original <jsp>.jsp hierarchy.

How to tell jspc to generate/compile files according
to JSP directory hierarchy?

Hi.

In addition to sacing resources on the webserver it
also allows you to 
run
your tomcat server (the live one) without javac being
on the machine - 
which
is a security step.

Hi,
	Yes..that is what I thought, but I learned from a
'reliable' source
I could accomplish this on saving overhead. So rather
than looking into 
the
whys and whats, I looked into how to do it, and look
into the 
performance
benefits later. I will provide the list with my
sources reasoning, when 
it
becomes available! 
	A thought..and to answer a question with a question
(Why would you
precompile jsp files?), why is jspc there? If only to
increase 
performance
on the first hit?

Thanks

Paul. 

It will increase speed on the first viewing of the
jsp, but after that 
I

can't see how there will be any difference.  How much
memory can you 
save 
if any?  And how would that work?

Thanks
