Question

I am using org.apache.log4j.RollingFileAppender and facing strange issue.
When I set log file name to process.log it does not roll over but when I set log file name to process1.log or process2.log it works fine and rolls over after given max file size.

log4j.appender.ProcessLogAppender=org.apache.log4j.RollingFileAppender
log4j.appender.ProcessLogAppender.File=D:/logs/process.log

log4j.appender.ProcessLogAppender.Append=true
log4j.appender.ProcessLogAppender.MaxFileSize=30KB
log4j.appender.ProcessLogAppender.MaxBackupIndex=5
log4j.appender.ProcessLogAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.ProcessLogAppender.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n

log4j.logger.com.util.ApplicationLogger=ALL,ProcessLogAppender

Create java logging class like this properly and read your property file through it. Restart server. These will solve this problem.

These lines are very important.

private static Properties loggerProperties = LoggerClassName.read(“log4j.properties”);

static Logger validation =
Logger.getLogger(LoggerClassName.class);

static {
  PropertyConfigurator.configure(loggerProperties);
  validation.setLevel(Level.DEBUG);
}
