log4j error?

[Samanthi perera]

here is my class

import java.util.logging.Logger;
import org.apache.log4j.PropertyConfigurator;


public class HelloWorld {

    static final Logger logger = Logger.getLogger(HelloWorld.class);

    public static void main(String[] args) {

        PropertyConfigurator.configure("log4j.properties");
        logger.debug("Sample debug message");
        logger.info("Sample info message");
        


    }
}

here is my property file
[code]
log4j.rootLogger=DEBUG, CA
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
[code]

i have already added log4j.jar file too

But you are importing java.util.logging.*

[Samanthi perera]

i change class

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;


public class HelloWorld {

    static final Logger logger = Logger.getLogger(HelloWorld.class);

    public static void main(String[] args) {

        PropertyConfigurator.configure("log4j.properties");
        logger.debug("Sample debug message");
        logger.info("Sample info message");
        


    }
}

now i got this error when i run project

run:
log4j:ERROR Could not read configuration file [log4j.properties].

[Jaikiran Pai]

As shown in the exception stacktrace, the:

PropertyConfigurator.configure("log4j.properties"); 

isn't able to find that file. Did you try specifying an absolute path of the log4j.properties?

[Samanthi perera]

how to give absolute path?

From here

An absolute pathname is complete in that no other information is required in order to locate the file that it denotes

So where exactly on your filesystem does that log4j.properties file exist. You will have to specify that entire path in the code.
