is possible write of console out debug.txt?

use configuration file add debug.txt target of fileappender:

<appender name="fileappender" type="org.apache.log4j.fileappender">     <file value="debug.txt" />     <appendtofile value="true" />     <layout type="org.apache.log4j.patternlayout">         <conversionpattern value="%date [%thread] %-5level %logger [%property{ndc}] - %message%newline" />     </layout> </appender>
