How to turn off logging from slf4j

It's a third party application generating huge amounts of logentries on our appserver. Like this:

[03.03.10 15:21:57:250 CET] 00000180 FtpProtocolHa I org.slf4j.impl.JCLLoggerAdapter info Close connection : 10.227.10.10 - admin
[03.03.10 15:27:35:209 CET] 00000181 MinaFtpProtoc I org.slf4j.impl.JCLLoggerAdapter info [/10.227.10.10] CLOSED
++++


How do I turn this output from slf4j off? I've looked in the .war-file to find some configuration for slf4j but nothing. Their website didn't help either

Answer

slf4j is just a funnel to the actual log backend (here overriding jakarta commons logging), which is the one you must configure to get rid of a certain kind of messages. For logback this is the appropriate configuration snippet:

    <!--  No Tomcat debug logs -->
    <configuration>
    ...
        <logger name="org.apache.catalina.core" level="OFF" />
    ...
    </configuration>

For log4j it is very similar.
