Charlie,
The following is messy, but just to give you an idea of the flavor of
the beast.
1) Put /java/jmx/lib/jmxri.jar
/java/jmx/lib/jmxtools.jar
/jakarta-log4j-1.2beta3/src/java
/jakarta-log4j-1.2beta3/dist/classes
into your classpath, changing directory names according to your
environment.
2) cd /jakarta-log4j-1.2beta3/src/java/org/apache/log4j/jmx
3) javac T.java
Do not skip step 3 even if the file T.class is already in the distrib.
4) java T
You'll see output similar to
0 INFO [main] org.apache.log4j.jmx.Agent - Registering HtmlAdaptorServer
instance.
0 INFO [main] org.apache.log4j.jmx.Agent - Registering
HierarchyDynamicMBean instance.

5) View http://localhost:8082/ with your browser. Do not stop or kill "java T".
6) Play around. You can add new appenders to categories, view and configure
appenders, add layouts...
JMX support is not production quality but the ideas are there. The existing
code needs polishing...
Any volunteers? Regards, Ceki
