Log output path problem

[Yansheng Lin <ya...@silvacom.com>]

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!
