How to configure custom log file in java web project

I am developing a java web application using eclipse IDE and jboss server (version 5). I am trying to implement a custom log file for my application with the following code : 

FileAppender fileAppender=new FileAppender(newPatternLayout(),Constant.LOGGER_PATH);
logger.addAppender(fileAppender);
BasicConfigurator.configure();
logger.setLevel(Level.ERROR);
logger.error(cause);

When I am trying to deploy my application to the jboss server it gives following exception : 

    18:35:16,346 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceError
    andler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" varia
    le.

It looks like your application has its own copy of log4j.jar bundles into its lib directory. This will clash with JBoss's own copy.

Remove that JAR from the lib directory and try again, your app will use the JBoss copy.
