Subject Blank JSP Instead of Exception
Date Thu, 10 Jul 2003 15:09:51 GMT
I'm building a new Struts app... and for the first half of development, 
uncaught exceptions would be reported by the container (on a web page 
that's visible to the end user).

Suddenly yesterday all exceptions stopped being reported to the web 
output, and are now only appearing as a StackTrace in stderr.log. The 
exceptions are Jsp compile errors (i.e.... I've typed an attribute wrong 
in a JSTL tag). It's really annoying to have to scan the stderr.log 
every time to debug a Jsp... how did I turn off error reporting?

I don't recall any substantial changes to my struts or web.xml 
configs.... and my code prints no stack traces... where is the stack 
trace coming from?

Also, how is it possible that I get valid HTML from the page, even when 
a JspException occurred compiling the page (here is actual output):

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<META http-equiv=Content-Type content="text/html; 

I am using tiles for the layout of the page.

Thanks for any help,
