Hello,
I am very confused about the state of logging in Java.
As far as I can tell so far, it appears that currently the log4j team
has dropped any plans to continue developing log4j 1.3, and this has
left the users to use log4j 1.2.15, while they develop the not yet
released log4j 2.0. Am I correct in this assumption?
That is correct. Much of the development around log4j 1.2.15 and the
companions were to make a reasonable migration path for log4j 1.3
alpha users back to log4j 1.2.x.
Currently I have been using log4j-1.3alpha-8 which I had to compile
myself since it isn't in any repository (probably due to its alpha
release state). I wouldn't normally use an alpha release, but it
seems to be a necessity since Chainsaw V2 will not place logging
events into two different tabs unless you use a (PropertyFilter) to
specify the Application and Hostname properties to the logging events;
Unfortunately, if you wish to add properties to logging events using a
simple configuration file, the use of log4j-1.3alpha seems required,
as log4j-1.2.x does not have the PropertyFilter class.
The PropertyFilter was problematic even in log4j 1.3 and couldn't be
implemented in log4j 1.2 without significant modification. It really
wasn't a filter and other appenders would see the changes that
PropertyFilter would make to the event. The RewriteAppender was
added to the receivers companion to provide the functionality
provided by PropertyFilter and MapFilter. See bug http://
issues.apache.org/bugzilla/show_bug.cgi?id=41483. The receivers
companion is expected to be released in conjunction with a Chainsaw
release. To build it assuming Maven 2.0.7 is on the path:
$ svn co https://svn.apache.org/repos/asf/logging/log4j/companions/
receivers/trunk receivers
$ cd receivers
$ mvn package
A sample configuration file for property rewriting is available at
src/test/resources/org/apache/log4j/rewrite/property.xml.
So my question is, at this point in time, what version of
log4j/chainsaw should I use to send logging events to separate tabs in
chainsaw?
Thank you,
Andrew J. Leer
You may be able to use log4j 1.2.15 + receivers 1.0-SNAPSHOT to
replicate what you were doing with log4j 1.3 without switching
Chainsaw versions.
The current Chainsaw SVN HEAD is based on log4j 1.2.15, but hasn't
been pushed to a release yet. To build it, you would do:
$ svn co https://svn.apache.org/repos/asf/logging/log4j/companions/
receivers/trunk receivers
$ cd receivers
$ mvn install
$ cd ..
$ svn co https://svn.apache.org/repos/asf/logging/log4j/companions/
zeroconf/trunk zeroconf
$ cd zeroconf
$ mvn install
$ svn co https://svn.apache.org/repos/asf/logging/chainsaw/trunk
chainsaw
$ cd chainsaw
$ mvn package
P.S. I'm using a SocketAppender to send the events to from log4j to
chainsaw. I tried using different ports to do this, but they always
end up in the same tab.
