Included below are my properties file ( properties.LogTest2.xml ),
my test driver ( LogTest2.java ) and the resultant output ( out ).
Basically, what I've done is subclassed Category, CategoryFactory and Priority.
I created a Priority called NOTIFY because I want to selectively write only
log events of that priority to a different log file. In my xml, I have an appender
called NOTIFY_TO_LOG which *attempts* to write all NOTIFY events
out to a file log_notification_out.txt.
As you can see from the output ( "out" below ), it appears that everything
runs as it should. However, the file log_notification_out.txt *does* get
created. However, it does NOT contain any data.
When I change the PRIORITY_TO_MATCH value in the xml file
from NOTIFY#com.ebss.utilities.PPCSPriority to INFO, the
log_notification_out.txt file *is* successfully written.
Does this imply that my subclasses are wrong ?
(thanks)

Jay,
I don't understand what you are trying to do. Can you give a distilled explanation for
dummies?
