Question

In my java swing application I load log4j properties from a properties file stored in a package in the application and I load that properties file as,

try {                            
     PropertyConfigurator.configure("conf/log4j.properties");
     logger.info("Starting the system.");                           

} catch (Exception e) {
     e.printStackTrace();

}

Then I get following error when the application is starts,

log4j:ERROR Could not read configuration file [conf/log4j.properties].
java.io.FileNotFoundException: conf/log4j.properties (No such file or directory)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:138)

        at java.lang.Thread.run(Thread.java:722)
log4j:ERROR Ignoring configuration file [conf/log4j.properties].
log4j:WARN No appenders could be found for logger (com.bio.ofm.mnu.views.SplashScreen).
log4j:WARN Please initialize the log4j system properly.

Is this way of loading property file is wrong? please help.

I build a .jar file and run the application using that jar**

If conf is the source folder you can use:

PropertyConfigurator.configure("classpath:conf/log4j.properties");

else you can try this:

PropertyConfigurator.configure(this.getClass().getClassLoader().getResource("conf/log4j.properties"));
