database appender
Hi everyone,
this is my first mail to this list und I'm also new to LOG4J.
So please bear with me :-)
I would like to send my logs to a table in a database .
Since there's no appender for this, my idea is to use
the SocketAppender and write a server which receives
the logs and stores them into the database.
Is there a more 'direct' way to do that?
Has anyone an idea?
Thanks, Thomas

I did this, but upon reflection, it seems to work against some of the
features of log4j. I later decided not to use it.

Basically, to change a class to use log4j implies the following
amendments:
* include an import line for the log4j Category
* create at least one static category in your class for logging (we
create two 'diag' and 'appl' to separate diagnostic versus
application messages
* exchange your System.out... (or whatever you use) for cat.log
statements
That's it ... you're in business.
When we looked at wrapper classes we realised that any we
produced would degrade performance, and imply significantly
larger changes to our classes. So wrappers won't necessarily
make the transition simpler.
And if you decide you need to switch to a different logging platform,
the route is easy:
* implement your own 'Category' which sends the output to your
new logging package.
* import your new Category class instead of the log4j one - which
would be a simple batch edit to your class sources
So again, any wrapper you produce would have to be pretty darned
good to make moving logging packages easier than this!

Sorry.. I am little lost on your explanation. I will better

That's what were doing. We run several apps in one WebLogic server. Each
app has it's own Category for logging. Works great.

We also considered this .... but when you look at the scope of
change if you want to move away:
* 1 import statement
* create your own version of Category to implement the new
interface to your new logging package
When you look at this, moving to a different package at a later date
is a pretty small deal.
I'd say concentrate you efforts in your Category naming hierarchy
since this is a pain to change later. Get this right, and log4J does a
fine job and would be easy to swap out later if you needed.
Just for info ... we're working with 2 category sets at the root of our
logging
DIAG.* developer and/or diagnostics messages
APPL.* application messages
Easy to control and filter.

Hi all,
I have just started using Log4J and I have some basic doubts. If
there are any docs. available kindly let me know.
1. I want to write a class which should accept the log calls from
other classes and log. If tomorrow I wish to change the log API
I should be changing only this class and not the other user
classes. (its something like facade pattern)
Is it possible ?
Cheers
