Sure. Just declare multiple filters. Example: <appender class="..."> <filter class="..."/> </filter> <filter class="..."/> </filter> </appender> If you look at the AppenderBase base class in logback-core [1], there is a method called addFilter(Filter). Joran, logback's configuration framework, can deal with getters and setters as well as "adder" methods. See the section entitled "Collection of Properties" in the logback manual [2]. Essentially, the "adder" convention is useful for dealing with a collection of properties, such as filters, instead of just a single property.

is it possible to support more than one filter in Appender...?
