How to disable SslFilter logging in apache MINA?

Question

I'am developing application based on apache MINA. For secure data transmission I use SSL. And there appears some annoying thing: when I receive incomming message, SslFilter class appends about 10kbytes to the log-file. How can I prevent this?

I finally found the solution for this problem. Here is the log4j.xml source:

<?xml version='1.0' encoding='ISO-8859-1' ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration>
  <appender name="CONSOLE-DEBUG" class="org.apache.log4j.ConsoleAppender">

    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{ISO8601} [%5p] %m at %l%n"/>
    </layout>
    <filter class="org.apache.log4j.varia.LevelRangeFilter">
      <param name="LevelMin" value="ALL"/>
      <param name="LevelMax" value="INFO"/>
    </filter>
  </appender>
  <appender name="CONSOLE-WARN" class="org.apache.log4j.ConsoleAppender">
