I think you should concentrate on the code for distinguishing the bundles. I am fairly certain that distinguishing the bundles is the crux of the problem. Once that is done, you can choose between multiple contexts or SiftingAppender. I suggest you post some code for discussion. When I think of the best way to distinguish between bundles, I think of creating new logging contexts based on installing/uninstalling bundles. Perhaps it's best to create a new OSGi service which creates new logging contexts based on bundle ID's or bundle names.
But for this to work I need to be able to create multiple name-based contexts within logback. The following (simplified) architecture would form: Logback < SLF4J < Custom Logging Service < CustomBundle With the above architecture I'd be able to determine which bundle wants to log something and would also be able to have a specific configuration per bundle. However this will only work if I'm able to create multiple contexts, is there a way for me to do this? I greatly appreciate your replies. Regards, Sander
