i have written a Xml file

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="">

<appender name="appender" class="org.apache.log4j.FileAppender">
<param name="File" value="Indentify-Log.txt"/>
<param name="Append" value="false"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %p - %m%n"/>

<priority value ="debug"/>
<appender-ref ref="appender"/>


and java file

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class externalplaintest {

static Logger logger = Logger.getLogger(externalplaintest.class);
public static void main(String arg[]){

logger.debug("This is Debug");
logger.debug("This not a Debug");



i am getting the following error. Can any one solve my problem

log4j:WARN No appenders could be found for logger (externalplaintest).
log4j:WARN Please initialize the log4j system properly.

warm regards

Try arranging your code so you try to create the Logger after you call PropertyConfigurator.configure.

For xml configuration use DOMConfigurator instead of PropertyConfigurator.

You can use -Dlog4j.debug to see what's going wrong with your configuration:

See the Short introduction to log4j for info about how to do get the debug flag set with tomcat if that's an issue.
I agree. Here's the link:
