and testing file in following ways:

public class log4jtest {     private static final logger log = logger.getlogger(log4jtest.class);      public static void main(string[] args) {          try {                     log.info("this info log-------------");                     log.warn("this warn log-------------"); //          throw new exception("new exception");          } catch (exception e) {             log.error("-----------this error log test------------", e);         }      } }

i need log generation in project , urgent if 1 know issue please let me know.thanks in advanced.
