You should really consider switching to Logger. All the old classes
(Category being one of them) have been deprecated (although only
unofficially, as they are not marked as such in javadocs) and are scheduled
to be removed sometime later this year.
That being said, the syntax using the Category class would be:
Category cat = Category.getInstance("com.mydomain.database");

Thanks a lot
But I use the Category, how can I get the com.mydomain.database by
Category?

Can you include your log4j.properties file?
Strictly based on the names of the files, it seems you want certain log
messages to go to A1 and all others to go to A2; then irregardless of
whether a message went to A1 or A2, also log it to A3. That correct?
In general that would be setup as:
log4j.rootLogger=INFO, A3
log4j.logger.com.mydomain.database=INFO, A1
log4j.logger.com.mydomain.other=INFO, A2
Then in your code:
Logger dbLog = Logger.getLogger( "com.mydomain.database" );
Logger otherLog = Logger.getLogger( "com.mydomain.other" );
I use this approach mainly for DB conversion programs where I need an
audit
log and an exception log.
If you didnt want to use 2 distinct loggers, you could look at using an
approach utilizing MDC. But in order to get that into 2 seperate files
you
would need to utilize Filters (which would additional mean a change to
an
XML config file).
