One that we'd like to see is some kind of pre-processor for JSP's . . .
think back to the old days of C and #IFDEF #ENDIF . . .

Justification:
In our environment, we do our development (and debugging) on the development
server.  Production code gets moved to the (you guessed it) production
server.  If we could include debugging statements in our code, ONLY on the
development server, life would be wonderful.  We currently do things like:

<%
    if (Config.isDevelopment)  e.printStackTrace (out);   // send trace to
browser

    e.printStackTrace (System.err);  // always send to error_log
%>

but we take that comparision performance hit on our production servers.  and
over multiple iterations, that kinda sucks.

I would rather be able to do this:

<%
#IFDEF _DEBUG
    e.printStackTrace (out);    // send trace to browser
#ENDIF

    e.printStackTrace (System.err);  // always send to error_log
%>

and _DEBUG (or any other variable) could be defined as an initArg of GNUJSP.
Obviously, the code between #IFDEF and #ENDIF would only be included in the
compiled servlet if the variable was defined.

Is there a widespread interest in this?  Does this violate the spec?  Why is
the sky blue?

Personally, I think this is a concept that should have been included with
JAVA, but they never asked me.

lemme know what y'all think.  if there is an interest, I'll prolly submit a
patch.
