Dynamic file and appender creation using Log4j under JBoss EAP 6.1

[mattso]

Hi all,

  I am able to merge existing log4j.xml into standalone.xml, so my module can use log4j (provided by JBoss - I did not pack my log4j jar in my module) for logging as well.

  I see that for appender and file that defined in standalone.xml, JBoss will create those file and register the appender so logging to those appender / logfile is not an issue.

  When I tried to dynamically create a appender (along with file name), and assign that to the logger, I expect log4j will create the file (in the FileAppener.setfile() method, bug 9150), and the appender will get registered without issue.  However, that is not the case - I cannot see the log file getting created in the file system, and I see a message complains that about null appender.

  Please let me know if I have missed any configuration / setting.  Thanks in advance!

Regards,

Matthew

What do you mean by dynamically creating an appender? Are you trying to get the log4j LogManager and adding appenders that way?

Hi James,

  Sorry for the late reply as I was re-assigned to focus on some other stuffs until now.

  Yes, that is exactly what I was trying to do - create appender with file path and pattern on the file and assign it to logger.

  Thanks for your help!
