A: Have a look at the file server/default/conf/log4j.xml. If you look at that file please be very careful about what is commented out: <!-- this is ignored for example -->
There are many examples included in that file, uncomment some and try them out.
Probably you want to start to play around with adding
to the <appender name="FILE" ...> section to limit the output to the logging file (performance issue!).
In many cases increasing the logging details to the console might help for debugging. Change the threshold ( in <appender name="CONSOLE" ...> ) to DEBUG for example.
The possible threshold values are:
DEBUG, INFO, WARN, ERROR and FATAL
JBoss3 is using log4j from the Jakarta Project for logging. Please visit http://jakarta.apache.org/log4j/docs/documentation.html for more details on the configuration of log4j.
