Intercepting Context exceptions

[Edoardo Causarano <ed...@gmail.com>]

Hello list,

I'm managing some legacy web apps, some jsp and other servlet based, that
lack good Exception handling (or at least Logging and reporting). Rather
than a plain blank page I'd like to return some infomative message within
sone nice html message. Most importantly I'd like to log these exceptions in
a more suitable way than the present.

How can I implement and install an Exception trap handler to perform at
least the said logging?

Thank you very much,
e

you have several options

1. implement a Valve that catches all exceptions and logs them
2. implement a filter (this will only catch within the application)
3. custom error page, and log the exception from there
