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

Subject: redirecting Stdout and stderr to a different log file
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
