Hi Java Gurus,
I am a sort of newbie to this Java World, but had to crack on some of the
Java error messages ASAP.
Given below are some of the error messages, which are frequently occurring
at our Production System. I would like to have a go at them, but would like
to receive some expert advice before having a go. It would be better, if we
are able to stop them from recurring OR could give some valid explanations,
why such an error is thrown.
For both of this, I look forward to your expert advice.

********************************************
I have literally some very basic questions. Pls. pardon me if I'm sounding
ignorant.
What does these errors mean at the face of it?
What should be my immediate steps?
Where I can look for details?
Where I can find the explanations/description about Java error messages?
Any Documents exist like the one exists for "Oracle error messages" for
Java?
Apart from the log files, Is there any other place, like ServletExec.log,
and Code, etc.,.... where can I look for more details?
In nut shell, what is the normal procedure of handling Java error messages?
I am familiar with handling Oracle error messages and know, what to do when
Oracle throws an error by just looking at the basic description of it, but
not Java at the moment.
If some one could show me the way, I can do this, as cracking on Java errors
is a bit new arena to me.
Any help on this would be appreciated.
Thanks n Regards,
Arun
