Hi, I want my log output to go to /WEB-INF/logs/ as specified in my
log4j.properties
------------------------------------------------------------------------
log4j.rootLogger=debug, stdout, ROOT_APPENDER
log4j.appender.ROOT_APPENDER=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ROOT_APPENDER.DatePattern='.'yyyy-MM-dd
log4j.appender.ROOT_APPENDER.File=WEB-INF/logs/debug.log
------------------------------------------------------------------------
But I am getting the following error when I run a test program:
------------------------------------------------------------------------
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: WEB-INF\logs\debug.log (The system cannot find
the path specified)

0 [main] INFO Log4JTest - Exiting application.
------------------------------------------------------------------------
The test program is:
-------------------------------------------------------------------
import org.apache.log4j.Logger;
import org.apache.log4j.BasicConfigurator;
public class Log4JTest
{
// Define a static logger variable so that it references the
// Logger instance named "Log4JTest".
static Logger logger = Logger.getLogger(Log4JTest.class);
public static void main(String[] args)
{
// Set up a simple configuration that logs on the console.
BasicConfigurator.configure();
logger.info("Entering application.");
System.out.println("program executing");
logger.info("Exiting application.");
}
}
-------------------------------------------------------------------
PS. I don't get the above error if I specify the output path to be:
log4j.appender.ROOT_APPENDER.File=debug.log
Oh, I aslo tried:
log4j.appender.ROOT_APPENDER.File=/WEB-INF/logs/debug.log
But got same error.
Thanks in advance!
