Displaying errors in JSP
If I have a code block such as
%
try {
}
catch (Exception e) {
}
%
inside a JSP, how do I output error to either the browser or
to the server console ?

RE: Displaying errors in JSP
for the terminal, you can use System.out.println(e.getMessage()) in the
catch phrase
for the jsp, you will need to initialize some string variable in the catch
block and then use in the html ...
%
String error = ;
try {
}
catch (Exception e){
error = e.getMessage();
}
%
...html stuff
p%=error%/p
But this isn't really always necessary. Orion will spit out the error in the
jsp if you don't catch it...since there is a try/catch built around every
jsp page. Try it...do something silly in the jsp page to create a Null
Pointer Error, and watch the fireworks in the browser. As long as you don't
have a 500 error page, your jsp Null Pointer Error will be in the browser.

BTW, if you use IE, disable 'friendly HTTP error messages'. This option, in
its active state will prevent the error page to display in the browser.

System.out.print() - server console
out.print() - HTML page
