Your mentions of EAR files make me wonder if the different "applications" are running in the same classloader - are they?
Have you put log4j in a common classloader shared by both applications? This might explain what you are seeing - IIRC web containers like WebSphere set up hierarchal classloaders for EAR applications, and a class which is loaded from the "shared" classloader will be shared by all child classloaders - in other words, the same log4j configuration will be used by all child classloaders (because there is actually only one instance of the configured log4j classes). It might be better to configure the specific loggers for each app, such as log4j.logger.com.yourcompany.web = ... log4j.logger.com.yourcompany.java = ... Also, not sure if you realize this but by passing in the log level to your logMessage(String strLevel, String Message) wrapper function, you lose any possible benefits of guard clauses and overly long messages not having to be concatenated by the JVM (http://logging.apache.org/log4j/1.2/faq.html#2.3). ________________________________________ From: S.Kannan [techy_k...@yahoo.co.in] Sent: Friday, September 11, 2009 11:40 PM To: log4j-user@logging.apache.org Subject: Logging done in the wrong files Hi All, A log4j newbie handling a bigger task .. This is my problem Hope somebody has got some solution for this. We have a web application as well as a java application. Both are big enough . But since both are managing the same business around 3 to 4 ear files are used in common for both the applications. Since we wanted to classify the loggers based on the application we have decided to have unique log.properties file. The following are the configurations in the log.properties file for web application log4j.threshold=ALL log4j.rootLogger=ALL,INFO_APPENDER,ERROR_APPENDER,DEBUG_APPENDER log4j.appender.DEBUG_APPENDER=org.apache.log4j.RollingFileAppender log4j.appender.DEBUG_APPENDER.MaxBackupIndex=50 log4j.appender.DEBUG_APPENDER.MaxFileSize=10MB log4j.appender.DEBUG_APPENDER.file=data/tda/logs/Logger_Debug_Web.txt log4j.appender.DEBUG_APPENDER.layout=org.apache.log4j.PatternLayout log4j.appender.DEBUG_APPENDER.Threshold=DEBUG for java application log4j.threshold=ALL log4j.rootLogger=ALL,INFO_APPENDER,ERROR_APPENDER,DEBUG_APPENDER log4j.appender.DEBUG_APPENDER=org.apache.log4j.RollingFileAppender log4j.appender.DEBUG_APPENDER.MaxBackupIndex=50 log4j.appender.DEBUG_APPENDER.MaxFileSize=10MB log4j.appender.DEBUG_APPENDER.file=data/tda/logs/Logger_Debug_Java.txt log4j.appender.DEBUG_APPENDER.layout=org.apache.log4j.PatternLayout log4j.appender.DEBUG_APPENDER.Threshold=DEBUG The following is the customized log manager class which we have written public class LogManager { String className; Logger objLog; static { InputStream logprops = LogManager.class.getClassLoader() .getResourceAsStream("path/to/log.properties"); try { Properties prop = new Properties(); prop.load(logProps); PropertyConfigurator.configure(prop); } catch (Exception e) { System.out.println("error in LogManager" + e.getMessage()); } } public LogManager(String className) { this.className = className; objLog = Logger.getLogger(this.className); } public void logMessage(String strLevel, String Message) { if (strLevel.equals("DEBUG")) { objLog.log(Level.DEBUG, Message); } else if (strLevel.equals("INFO")) { objLog.log(Level.INFO, Message); } else if (strLevel.equals("WARN")) { objLog.log(Level.WARN, Message); } else if (strLevel.equals("ERROR")) { objLog.log(Level.ERROR, Message); } } } And in each class files we have called the logmanager like private static final LogManager logMgr = new LogManager(QueueListener.class.getName()); logMgr.logMessage("INFO","QueueListening starts."); Now our problem is that most of the times the messages in the Logger_Debug_Java.txt is routed to Logger_Debug_Web.txt once a class which is common for both application executes. Then the thread or control does not go back to the Logger_Debug_Java.txt file.
