You mean how are the changes to log4j.xml (or jboss-log4j.xml) in the conf folder of JBoss being noticed when the server is running? It's actually not Log4j which does that. JBoss creates a java.util.TimerTask which periodically checks the lastUpdateTime of the file and invokes the appropriate APIs in case of any changes to that file.

thanks for your quick reply jaikiran.

is it correct to use timertask for file change listeners from my ejb3 application ?

i had already some problems with threads into my ejb application.


i thought maybe there is some abstract class for listening configs into jboss.


i could do this by timertask.


thank you very much again.

I don't exactly know the requirements of your application. But, you need not do this logic in your EJBs. See this documentation http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Server_Configuration_Guide/beta422/html/Additional_Services.html#Additional_Services-Scheduling_Tasks for one possible way of scheduling tasks to handle this.
