RE: redirecting Stdout and stderr to a different log file

Hi Umesh,

 You can define a custom appender and associated logger for this purpose and
then use that logger in your SysOutErrRedirector.

 Sample code:

------------------------------
public class SysOutErrRedirector
{
        private Logger logger;

        public SysOutErrRedirector(Logger myLogger)
        {
                super();
                logger = myLogger;
                initialize();
        }

        /**
         * Initialize the redirection.
         * 
         * @param myLogger
         */
        @SuppressWarnings("rawtypes")
        private void initialize()
        {
                Enumeration e =
LogManager.getLoggerRepository().getRootLogger().getAllAppenders();
                while (e.hasMoreElements())
                {
                        Appender appender = (Appender) e.nextElement();

                        if (appender instanceof ConsoleAppender)
                        {
                                if (((ConsoleAppender)
appender).getFollow())
                                {
                                        ((ConsoleAppender)
appender).setFollow(false);
                                        ((ConsoleAppender)
appender).activateOptions();
                                }
                                logger.removeAppender(appender);
                        }
                }

                System.setOut(new PrintStream(new
LoggingOutputStream(logger, Level.DEBUG), true));
                System.setErr(new PrintStream(new
LoggingOutputStream(logger, Level.ERROR), true));
        }
}

Thanks,
 Himanshu

Hi Himanshu,

I am able to redirect the sysouts and syserr to a file. But I need them in a
individual file so that it is not combined with other logs.

Can you help me out 

Regards,
Umesh

Hi Umesh,

 You can write a SysOutErrRedirector which can take out and err streams and
use log4j root logger (or any other defined logger) to move it to the
associated appender.

Thanks,
 Himanshu

Hi All,

We have lot many sysouts in our project. The sysout are captured in file by
using a redirect operator when we launch the server.
The maintanence of the files a big issue as these logs keep on growing.

Can you please help me find out a strategy if I can redirect all the sysout
and stderr into a logging file using log4j.

Thanks and regards,
Umesh Paliwal
