If i have a syntax error on my jsp, let's say, not in the script, but some
html tag. i.e. forget to close a tag.
How can i configure tomcat to give me the error stack on the page source?
right now, it gives me blank page...

o. Not about the fixing of the compilation.
We have group of site designers they only develops JSP pages but
knows little about java.
What they complain is that when they wrote JSP, they could not have any clue
where is the JSP is wrong, they want to see the error message on their
browser.
they have no clue about what is printed to the tomcat console...

use some IDE or jsp editor, which can give error message on the fly.

The error message is not html error, more like jsp or
servlet error which a developer should go in and fix.

for some error, there is the error page you can resort.
for some other errors, you have to read the console。

If this is a JSP error, you will see the error in the log file.
Blank page is normally caused by NullPointerException or some common Exceptions that were not caught properly.

true.
issue is web designers want the error stack showing on the browser

Exceptions that were not caught properly.

Tomcat only print the JSP error. In order to print your own stack, you need
to catch that exception, store the message in the session.
When rendering the JSP page, check if message is null, if not, print it.

Post your code snipet and let us know what do you want to do. So we can
provide some help.

no special codes. it is a general request to redirect a portion of
logs, to be specific, the JSP compiling log, from console to web browser.

That probably depends on your app server.
I use tomcat exclusively and jsp compilation error
is showed on web browser automatically.

I think in tomcat everything that blows up blows
all the way up to the browser window, and you'd
have to specifically configure it _not_ to do so.
I would start with the web.xml from your own app's
and see if there are any error pages declared.
