Since you're using the xml properties, set up 2 different loggers, and 
then attach filters to them.

Keep in mind that when attaching multiple filters to the same logger, 
that if the statement fails one filter, it will pass down to the next. A 
denial by a filter does not necessarily mean that the message is thrown 
away, the message just fails that filter and goes onto the next one 
(except in the case of DenyAllFilter). Which is why it's always safest 
to have a "DenyAllFilter" at the bottom of the list to catch the 
stragglers.

The filters you would need for this specific project are in the log4j 
package already.

e.g.

<log4j:configuration>
   <appender name="infoLogsFile" class="org.apache.log4j.FileAppender">
      <layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{MM-dd-
yyyy HH:mm:ss} %-5p %c - %m%n"/>
      </layout>
      <param name="file" value="info_messages.log"/>
      <filter class="org.apache.log4j.varia.LevelMatchFilter">
			<param name="LevelToMatch" value="INFO"/>
			<param name="AcceptOnMatch" value="true"/>
      </filter>
      <filter class="org.apache.log4j.varia.DenyAllFilter"/>
  </appender>

  <appender name="otherLogsFile" class="org.apache.log4j.FileAppender">
      <layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{MM-dd-
yyyy HH:mm:ss} %-5p %c - %m%n"/>
      </layout>
      <param name="file" value="other_messages.log"/>
      <filter class="org.apache.log4j.varia.LevelMatchFilter">
			<param name="LevelToMatch" value="DEBUG"/>
			<param name="AcceptOnMatch" value="true"/>
      </filter>
      <filter class="org.apache.log4j.varia.LevelRangeFilter">
			<param name="LevelMin" value="ERROR"/>
			<param name="LevelMax" value="FATAL"/>
			<param name="AcceptOnMatch" value="true"/>
      </filter>
      <filter class="org.apache.log4j.varia.DenyAllFilter"/>
  </appender>

  <root>
		<priority value="ALL"/>
		<appender-ref ref="infoLogsFile"/>		
                <appender-ref ref="otherLogsFile"/>
  </root>
</log4j:configuration>
