I don't think you can specify filters in the properties file format - use an
xml config file instead.
Here's an example:
<appender name="someAppender" class="org.apache.log4j.FileAppender">
<layout class="org.apache.log4j.SimpleLayout"/>
<filter class="org.apache.log4j.varia.ExpressionFilter">
<param name="Expression" value="msg ~= blah" />
<param name="AcceptOnMatch" value="true"/>
<param name="ConvertInFixToPostFix" value="true"/>
</filter>
<filter class="org.apache.log4j.varia.DenyAllFilter"/>
</appender>
The denyallfilter makes sure the events are dropped if they weren't accepted by
the expression filter.

Hi ,
We are using Struts framework for our product(application) and using
logj.properties file to configure logging.
How can i configure Expression-based filters in log4j.properties? Is it
possible to configure in properties file?
One more basic question, Can we use both log4j.properties and log4j.xml file
to configure for an application?
Could anyone clarify me.
Thanks
