Subject Re: Specify Repository
Date Wed, 09 Apr 2008 21:52:13 GMT
Your repository selector selects the repository.  You set the repository 
selector by calling LogManager.setRepositorySelector(selector, guard).  Note 
that the guard is provided so that if someone else comes along a tries to 
reset it, they will get an IllegalArgumentException and be prevented from 
overriding the initial setting.  This is because the selector is global to the 
Log4j instance.  Repository selector setting is meant to be done at 
application startup.  When running inside an application server, it should, 
ideally, be set by the server.  However, if you are the only app to use it, 
you could have a servlet context listener do this upon application startup.


As you can see, this has nothing to do with logger statements.  Your code 
doesn't have to change in order to use a repository selector.
