I have been using the old built firebird driver and it is working
fine. I just updated to the recent one, but have difficult to use it
related to log4j.

First my application does not use log4j. I built the driver
successfully. However, when I test a simple application, it raised

log4j:ERROR No appenders could be found for category
(org.firebirdsql.jca.FBManagedConnection).
log4j:ERROR Please initialize the log4j system properly

My questions are
1) what I will need to do to build, Do I need to edit the log4j
properties?

2) Do I need to do any thing in my application to use the driver?
