• Logger.setLevel() doesn't enable logging correctly

  - by ripper234

  Situation: I have this log4j logger: private static final Logger logger = Logger.getLogger(ThisClassName.class); And am trying to set it programatically through: Logger.getLogger(ThisClassName.class).setLevel(Level.DEBUG); Still, DEBUG level prints are swalloed (while INFO prints are printed successfully). Even this bit has no effect: Logger.getRootLogger().setLevel(Level.DEBUG); Calling logger.debug("foo") reaches Category.forcedLog() and ConsoleAppender.doAppend(), and then fails (quits) at: if(!isAsSevereAsThreshold(event.getLevel())) Any idea why this is happening?

• Error when trying to use hibernate annotations.

  - by Wilhelm

  The error I'm receiving is listed here. That's my HibernateUtil.java package com.rosejapan; import org.hibernate.SessionFactory; import org.hibernate.cfg.AnnotationConfiguration;; public class HibernateUtil { private static final SessionFactory sessionFactory; static { try { // Create the SessionFactory from hibernate.cfg.xml sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory(); } catch(Throwable e) { System.err.println("Initial sessionFactory creation failed. " + e); throw new ExceptionInInitializerError(e); } } public static SessionFactory getSessionFactory() { return sessionFactory; } } Everything looks all right... I've already included log4j-boot.jar in the CLASSPATH, but didn't resolved my problem.

• Logging from multiple apps/processes to a single log file

  - by Andrew

  Our app servers (weblogic) all use log4j to log to the same file on a network share. On top of this we have all web apps in a managed server logging errors to a common error.log. I can't imagine this is a good idea but wanted to hear from some pros. I know that each web app has its own classloader, so any thread synchronization only occurs within the app. So what happens when multiple processes start converging on a single log file? Can we expect interspersed log statements? Performance problems? What about multiple web apps logging to a common log file? The environment is Solaris.

• Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

  - by ?????

  My catalina logs are filling up with gobs of statements like: /logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4] [0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb] [0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8] on and on forever. I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here: http://hc.apache.org/httpclient-3.x/logging.html And I don't see where this logging as been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it. Any ideas? I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

Could anyone tell me what is going wrong here. why does it print logs when running from eclipse ide and, why is it not printing logs when it is started

• Java: library that does nice formatted log outputs

  - by WizardOfOdds

  I cannot find back a library that allowed to format log output statements in a much nicer way than what is usually seen. One of the feature I remember is that it could 'offset' the log message depending on the 'nestedness' of where the log statement was occuring. That is, instead of this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java| 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java| 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 459 | Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java| 789 | Another debug message It would shows something like this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java | 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java | 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 459 | |__ Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java | 789 | |__ Another debug message This is an example I just made up (VeryLongCamelCaseClassNamesNotMine). But I remember seeing such cleanly formatted log output and they were really much nicer than anything I had seen before and, in addition to being just plain nicer, they were also easier to read for they reproduced some of the logical organization of the code. Yet I cannot find anymore what that library was. I'm pretty sure it was fully compatible with log4j or sl4j.

• What is an appropriate way to separate lifecycle events in the logging system?

  - by Hanno Fietz

  I have an application with many different parts, it runs on OSGi, so there's the bundle lifecycles, there's a number of message processors and plugin components that all can die, can be started and stopped, have their setup changed etc. I want a way to get a good picture of the current system status, what components are up, which have problems, how long they have been running for etc. I think that logging, especially in combination with custom appenders (I'm using log4j), is a good part of the solution and does help ad-hoc analysis as well as live monitoring. Normally, I would classify lifecycle events as INFO level, but what I really want is to have them separate from what else is going on in INFO. I could create my own level, LIFECYCLE. The lifecycle events happen in various different areas and on various levels in the application hierarchy, also they happen in the same areas as other events that I want to separate them from. I could introduce some common lifecycle management and use that to distinguish the events from others. For instance, all components that have a lifecycle could implement a particular interface and I log by its name. Are there good examples of how this is done elsewhere? What are considerations?

• How do I configure logging for a grails plugin ?

  - by Philippe

  Hello, I'm creating my first grails plugin and I don't know where the logging should be configured. In a normal grails app, there is a conf/Config.groovy file for that, but for a plugin there is none. Is there another way to achieve this ? I would like to see debug messages when I launch my plugin unit and integration tests... Thanks in advance. Philippe

• What do you think of saving stack trace in a special log table ?

  Suppose, you have a special log table of your application. What do you think about creating a BLOB field for a possible stack trace ? Logging is done to file as well, but it is not so convenient to read a text file, moreover database is more "accessible".

• log4j vs. System.out.println - logger advantages?

  - by wishi_

  Hi! I'm newly using log4j in a project. A fellow programmer told me that using System.out.println is considered bas style and that log4j is something like standard for logging matters nowadays. We do lots of JUnit testing - System.out stuff turns out to be harder to test. Therefore I began utilizing log4j for a Console controller class, that's just handling commandline parameters. // some logger config org.apache.log4j.BasicConfigurator.configure(); Logger logger = LoggerFactory.getLogger(Console.class); Category cat = Category.getRoot(); Seems to work: logger.debug("String"); Produces: 1 [main] DEBUG project.prototype.controller.Console - String I got two questions regarding this: From my basic understanding using this logger should provide me comfortable options to write a logfile with timestamps - instead of spamming the console - if debug mode is enabled at the logger? Why is System.out.println harder to test? I searched stackoverflow and found a testing recipe. So I wonder what kind of advantage I really get by using log4j.

• Seam-gen isn't working properly.. log4j acuses an error

  - by rgoytacaz

  Hello Seam Users, I'm having a couple problems with my Seam start up. I did the ./seam generate to reverse my current postgres db, which contains 4 tables, first I though everything was okay, just a warning message, but when I imported the project into eclipse, I saw that none of my packages had any class. This is the error that seam generate, got me. [hibernate] Executing Hibernate Tool with a JDBC Configuration (for reverse engineering) [hibernate] 1. task: hbm2java (Generates a set of .java files) [hibernate] log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). [hibernate] log4j:WARN Please initialize the log4j system properly. [javaformatter] Java formatting of 0 files completed. Skipped 0 file(s). Any ideas?
