[logback-dev] Multiple Binding

[Durchholz, Joachim]

> Is there any direct or indirect way of implementing both log4j and logback.

See http://www.slf4j.org/legacy.html#log4j-over-slf4j .

Well, you need to replace log4j.jar with log4j-over-slf4j.jar in the classpath, so you need to control its classpath.
If you don't, the situation is much more complicated than usual and we'd need to know what aspects of the situation you control.

slf4j supports that out of the box.
