The first way is not welcome for sure, since at that case the original
exception would be lost
(in case there was some, causing this somethingBad to happen)
But I don't understand the reason for calling RequestUtils.saveException
in second case. If we configure an error page in web.xml then we can access
the exception just with *exception* variable which is defined on every jsp
page.
This error page would be a good place to log the exception as well.
Please correct me if I am wrong.
