-----------------------------------------
As you can see, log4j is jumping all over the place. I've marked sections with *s and a message above. Is this normal behavior (like a stack storage or something)?
I am going to read the docs yet again, but if you know whats going on here, plz let me know.
Thanks Karan

I suggest starting by specifying the "log4j.debug" system property when you launch startup. You can often find out exactly what's going wrong with that.

Hi,
I am running TC + Hib + Struts. I have log4j.jar in the classpath. The following is the log4j.properties of my web application. The files struts.html and hibernate.html are created automatically everytime TC reads log4j.properties. However, nothing is ever written into them. I have log4j.jar in both my_application/WEB-INF/lib and in tomcat/common/lib. I do not have commons-logging in both the lib paths.

I did make struts and hib2 part of the rootLogger, but then all messages are stored in the struts.html and hibernate.html (basically they become copies of all.html). Moreover, the reason I'm implementing logging in this manner is because I want to seperate the logging of different layers of my application. In beans: -- goes to singlemote.html private static Logger log = Logger.getLogger("singlemote.bean"); In DAOs: -- goes to singlemote.html private static Logger log = Logger.getLogger("singlemote.dao"); In HibernateUtil.java: -- goes to HibUtil.html private static Logger log = Logger.getLogger("singlemote.hibutil");
Any help is greatly appreciated.
Also, Off-topic: how do I make log4j pick up $catalina_home from the env and use that to specify the destination path for the generated log files.
Thanks,
Karan
