Subject Re: version change....
Date Mon, 29 Jan 2001 15:12:36 GMT
People should be aware that the last couple of major log4j releases have
involved name changes: the 1.0 release some particularly significant ones
(i.e. the whole package structure).  If you were careful to have most of
your initialization in one place and used import statements instead of
fully qualified package names in your source, you are relatively unscathed.
Otherwise the rework can be rather significant.

If you have a network of application servers sending logging events to
various listeners, this can be a problem.  Every place in the path of a
logging event must be updated at the same time since a serialized 0.9
LoggingEvent class is not compatible with a serialized 1.0 LoggingEvent
class.  Thus from the time you change the first app server to the time you
change the listener and everything in between, logging will fail (of course
you still have the local logs on the app server).

As Anders Kristensen mentioned earlier, all existing versions of log4j are
compatible with JDK 1.1 or above, including JDK 1.2 and JDK 1.3.

It is recommended (but not necessary) that you upgrade to the latest
version of log4j. Newer versions are more feature rich. More importantly,
new versions fix any existing bugs in older versions. So even if you do not
use the newly introduced features, you are likely to gain by the bug fixes.
On the other hand, if you are happy with the existing log4j functionality,
there is no need to upgrade. Cheers, Ceki

ps: You can make a more educated decision on whether to upgrade or not, by
reading the HISTORY file: http://jakarta.apache.org/log4j/doc/HISTORY
