Hi Jake, I see. But if the log4j-config is reloaded each time that application is called, the appender gets loaded with the current values of the Properties (actually System.properties). I ried that already. If I get the way of your sugesstion right, the application itselve would be supposed to code the configuration for a certan appender type. That is probably doable, but seems to me a bit contradictional to the ability to configure appenders of what kind ever. I mean why should an application know about what appender type and name is used in log4 configuration? I am afraid the logger then is loosing a lot of configuration flexibility, does'nt it?

Even the solution I proposed only applies the one time. It just allows you to define local properties rather than depending on System properties set JVM-wide. You have to obtain an reference to the appender object and re-set its properties. This is most certainly doable. Just look up a logger that the appender is assigned to and use getAppender("appenderName"). Then you can modify the appender to your heart's content.
