Tomcat log4j .
Hi all,
I am using Tomcat 4.1.27 + log4j 1.2.8+Win2k sp4. I have some problems
with it.
1, Log4j locks the log file so that I cannot clear the content of the file.
After some time I want to delete old debugging data while development.
Currently I am doing it by shutting down Tomcat. It is time consuming job.
2, After a context reload in Tomcat, if anyting is written to log the editor
dont say that the file is changed. It is not changing the last modified
date of the log file.
log4j jar file is in application's WEB-INF\classes\lib directory.
log4j.properties is in WEB-INF\classes
No initialisation servlet is there.
Some questions
1, What is the SSS in the ConversionPattern means ?
2, Is it necessary to initialise log4j through a servlet ?.
rgds
Antony Paul.

1. You could use rolling files and delete the old ones, or even better, upgrade
to linux :-)
>2, Is it necessary to initialise log4j through a servlet ?.
No. It can be done in a jsp also, if that is what you mean, ie: put 'Logger
lgErr = Logger.getLogger("ErrLog");' where you have defined ErrLog in your
properties file.

Don't beleive SSS mean anything - should just print out 'SSS'

You need to do a LogManager.shutdown() upon application shutdown. That will
solve problems with Log4j keeping handles on files. Use a Servlet Context
Listener for this.

You can close the appender in question. Calling LogManager.shutdown() will
close down all appenders.
This code can be added to the
<../../javax/servlet/ServletContextListener.htm#contextDestroyed(javax.servlet.ServletContextEvent)>contextDestroyed(<../../javax/servlet/ServletContextEvent.htm>ServletContextEvent
sce) method of a
ServletContextListener.
See for example:
http://www.mail-archive.com/log4j-user@jakarta.apache.org/msg10001.html
Hope this helps,
