Antw: RE: Performance between Log4j and custom in-house logger

Dear skk, Reading your XML file I do not see you use AsyncAppender but I see you still use two files to log to. As Ceki mentioned with an extra task for writing the messages you burden the job to someone else. To extend the analogue Ceki used the job is still in the office (CPU) and it may deg

Hi, I did the test with AsyncAppender using an xml config file(set the buff size to 1000 even though default size of 128 should be sufficient. My logger uses a size of like 60 ) and it seems the performance isn't any better. Infact the performance dropped a little and it seems to vaildate the As

The MDC class depends on JDK 1.2 at compile-time. At runtime, it will not do anything under JDK 1.1 (it won't work but it won't harm your application either). Other than that lf5, chainsaw depend on JDK 1.2 or more precisely swing. The TelnetAppender and JDBCAppender also depend on JDK 1.2. At

I have a pressing need to integrate log4j into jdk 1.1, meaning that I need the source code to be compiled along with the rest of the system. (Setting a classpath or Including the precompiled class files is not an option, unfortunately.) I have been tinkering with surgically removing any java

Re: JMX

Log4j has pretty decent facilities to manage the logging pieces like changing logging levels, changing logging format, appenders etc. As u said, it is still in nascent stage and I also remember Ceki posting a request for developers to enhance JMX. I am currently testing log4j integration wi

RE: Unexpected Exception launching through Ant

I beg to differ. You probably recompiled in the upgrade process. If you go back to 1.2.5 the problem will still be "solved". The difference between 1.2.6 and 1.2.5 cannot cause a java.lang.VerifyError exception. At least not in a rational world. Nevertheless, thanks for reporting back. At 09:14

Re: Problems with Xalan/Xerces using Log4J 1.2.3 withWebSphere 4.01

I think you were on the right track. But just because you have xerces and xalan in the WEB-INF/lib directory doesn't mean log4j.jar will find it there. If the log4j.jar is placed in the "lib/app" directory as you described, it will not be loaded by the module classloader. Instead the Applica

RE: DailyRollingFileAppender does not create backup file

Are you running log4j in a standalone application or as part of a servlet container like Tomcat? I'm running it under Tomcat and when it doesn't work for me I can see the following error in stderr.log: log4j:ERROR Failed to rename [e:/WebApps/atmreports/cvsroot/ATMReports/ATMRealtime_NYCE/WEB-INF

RE: DailyRollingFileAppender does not create backup file

Keep in mind that the DailyRollingFileAppender is not supposed to roll over exactly at the time specified, merely at the first log-event that occurrs after that time is passed. The reason is simply that the rollover is handled in the same thread as the logging occurrs. -- Thomas | -Origina
