Hello Ceki,
This sounds like a vialable way, that somehow matches my current log4j based hack. Is this appender already available? I had a quick look at the 0.9.11 sources and didn't find any.
No it is not available.
Additional detail would be nice. For example, how are you managing thread local values in the web-app and in ejbs? For web-apps I currently use a servlet filter, which sets a thread special thread local variable to the value of a special context param in the webapp. This matches the MDC approach using servlet filters.
For ejb's this proves a bit more difficult (at least EJB2, havent checke EJB3 so far) since there is no standardized support for custom EJB interceptors. Currently I am using aspectj to weave an aspect around the ejb implementation class - which sets the thread local.
A third use case are workmanager and timer threads (Websphere 6.1), where the aspect aproach also works - here the context setting aspect is applied the work item implementation classes (basically a Runnable implementation).
I see. Thank you for this explanation. -- Ceki Gülcü Logback: The reliable, generic, fast and flexible logging framework for Java. http://logback.qos.ch
