Hi,
I am probably missing something but...
If your ApplicationClasses run in separate VM instances
from each other, you could configure the category/appender
relationship at runtime using the Category class static methods.
Once, at the beginning of your "application class" use the
Category methods like setPriority() and addAppender()
to set the logging state of the utility classes that it will call.
For Example:
Assuming you had a predefined appender for BetaCalc called
BCFileAppender. You could try this at the beginning of BetaCalc:
Category catVP =
Category.getInstance("swissrisk.databaseLayer.VolatilityPeer");
Appender appBC =
Category.getAppender("BCFileAppender");
catVP.addAppender(appBC);
// Now instantiate and call VolatilityPeer methods.
Hope this helps...
- Joe
