Hi all,
Does anybody know if there is any particular care to let Log4j log
inside a servlet?
By now, I've just added the log4j.properties file in WEB-INF/classes
(under Tomcat) of my application, as suggested in the short-manual
(http://jakarta.apache.org/log4j/docs/manual.html).
Am I
Hi,
- create a servlet with an init method, which configures your log4j
properties.
- WEB-INF/webx.ml create an entry to init the servlet while server start.
One property of this entry is the path to your log4j config-file (if your
file is in /classes you can use reflection
Thank Shapira,
Canyou tell me some properties that are nor reset-able ???

That's true. My solution requires servlet API 2.3 or later, and I
should've mentioned that. In fact, until v2.3 came out, I had a

Hi,
You need to use a DailyRollingFileAppender. You'll get the rollover and
file naming (no overwriting). See the javadoc for
org.apache.log4j.DailyRollingFileAppender and examples in the mailing
list archives for this list.
Unless I completely misunderstood your question?

Jacob Kjome has pointed us at his log4j init servlet in the past. It is
really quite full featured and definitely worth taking a look.

Yoav's point about using the context listeners (requiring Servlet 2.3) is
very valid, and going

Howdy Jacob,
Actually, If you look in my post, I mention more than just the
Log4jInit servlet. I also mention a servlet context listener
(SCL) called
Log4jApplicationWatch. I actually use that currently to do cleanup
such as shutting down loggers and appenders of the currently used
Actually, the main thing I'd propose is having Log4jCRS (Log4j
Contextual Repository Selector) be included with the Log4j
distribution. The reasons for this are described in my post
that Mark
linked to above.
I know this is not a vote, but +1 on that. As part of the
contrib tree,

MW Jacob, do you think you can make an official apache submission (with all
MW the correct apache headers, etc)?
Is there some place that describes all that, or should I just copy the
license from some other Log4j file and paste it into Log4jCRS?

This is really two problems, but since it is concerned with logging I give you both.
We have created a Java client, and now we wish to log all uncaught exceptions. As it
is now exceptions thrown in threads and other uncaught exceptions are written to
standard error out I believe.
I think that I
Hello Mark,
One more question. What package might it exist in? My best guess
would be org.apache.log4j.spi? I'll assume that unless you tell me
differently.

Use Jim Moore's LoggingOutputStream. You'll find it in his log4j contrib directory in
the release. The javadoc describes how to use it to redirect System.out and System.err.

Hello Mark,
Here it is (zip file attached).
I set the package as org.apache.log4j.spi and commented out the
imports from that package. If it is going to a separate package, feel
free to modify it.

If I send logs from one app to another over SocketAppender and the listener
writes to a FileAppender, am I correct that write permissions are dependent
only on the user who ran the server, and NOT the user who generated the
log?
Put another way, Log4j doesn't care about userid's and passwords?
Thanks! If you had to rename this class, would
ClassLoaderRepositorySelector or ClassLoaderSelector be okay? Since it will
in log4j, I don't think the class name needs to start with Log4j...

One possible one-shot-kill-all-birds solution is to use the JNDI

(in particular JNDIRS). What do you think?
I also suggested the JNDI solution in commons-dev in a somewhat
different context. It seemed to be well received.

Yes, we can reasonably do that. However, I am unsure about the
maturity of any of these approaches without proper

Are you sure about that?
Positive. The example in SRV 10.2.2 makes this clear. I've also
inspected the code in tomcat and resin myself and they both implement
the spec the same way.
