I have my file as below:

<<<<<<<<<<<<<log4j.props file>>>>>>>>>>>>>>>>>>>>>>
log4j.rootLogger=info, stdout, R

# Pattern to output the caller's file name and line number.
#log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c "%l" %x - %m%n
log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c{2} %x - %m%n

# Set appender for log files
# Keep one backup file

#log4j.appender.R.layout.ConversionPattern=%d %-5p %c %l - %m%n
log4j.appender.R.layout.ConversionPattern=%d %-5p %c{2} - %m%n

<<<<<<<<<<<<<<<<<< ends here>>>>>>>>>>>>>>>>>>

<<<<<<<<<<<<<<<LogInit servlet>>>>>>>>>>>>>>>>>>>

public class LogInitServlet extends HttpServlet {

// private Logger log = Logger.getLogger(LogInitServlet.class);

public void init() {

//"*********Invoked Logging*************");
String prefix = getServletContext().getRealPath("/");
String config = getInitParameter("log4j-init-file");
//"Initializing Log4j from config file: " + prefix + config);

if (config != null) {
PropertyConfigurator.configure(prefix + config);

public void doGet(HttpServletRequest request, HttpServletResponse response) {


<<<<<<<<<<<<< ends here>>>>>>>>>>>>>>>>>>>>>>>>>>>>

<<<<< added to web.xml>>>>>>>>>>>>>>>>>>

<<<<<<<<<<<<<<<<<<ends here>>>>>>>>>>>>>>>>>>>>>>>>

The logging is working fine when I execute the code on Tomcat on my m/c. But when I push to dev server, it is not writting to myApp.log.

Appreciate help.

You said it isn't writing to the log file. Does that directory exist on the dev server? What IS it doing, logging to console or no logging at all?

Adding -Dlog4j.debug can be helpful if it is not logging at all. See log4j short manual for info on adding that to the tomcat options if needed.

The directory and file name exists on the dev server.

It is writtng. But writting to file localhost_log.txt

I see that this file name is mentioned in server.xml. Is it necessarry ? Can I delete that?

The line is hereunder for your review:

<Logger className="org.apache.catalina.logger.FileLogger" debug="0" directory="logs" prefix="localhost_log." suffix=".txt" timestamp="true" verbosity="1"/>

Thanks for the reply

Hi Carol

Can you look at my code and give me some clue?

Perhaps a tomcat user can help out. If I were you I would modify the subject line to include log4j and tomcat.
Don't get me started about those stupid light bulbs.
