Yes, totally. You can log your messages to a jdbc db, xml file, email,
syslog ...

Check then log4j docs, they have good samples.

I don't know much about log4j so I have a question for you. Is it possible
to obtain an appender that can log to JDBC? I know it is silly to log to a
database but this would be a straightforward route for me to log my messages
into a relational database in my test environment. Do you know anything
about an appender for JDBC?

Thanks,

Subject: [HAPI-devel] logging task progress

I've done some progress in replacing the hapi home grown logging  mechanism
with the jakarta-commons-logging framework.

DONE:

- All references to the hapi Log interface has been removed and the Log
interface itselft, plus related classes have been marked as deprecated.
- package ca.uhn.log has been added.
- interface HapiLog, and classes HapiLogImpl and HapiLogFactory have been
added to pachake ca.uhn.log.

- the javadoc of the class HapiLog contains information about how to use the
new logging framework.

- exception classes have been changed to contain the cause of the exception.
- in all places where the an error is being logged and an exception is being
propagated have been modified to only propagate the exception-and the cause
of it (to avoid having the same problem logged twince)

NOTE that now hapi depends on the jakarta-commons-logging framework.

TODO
- look into replacing the class Status with well known patterns of
jakarta-logging usage. Meaning that if want to output status information,
the underlying logging framework must be used, by invoking the log.info( ...
) method.
- create a std hapi log4j cinfiguration file.
- ...
