1. Re: Custom log4j Appender
chrisabney123 Jun 20, 2002 2:27 AM (in response to cwstanton)I am not quite sure about your situation but I think the solution will be:
1. Make sure your custom appender class is declared public
2. Programmatically add the appender to a log4j Logger (called Category in older log4j) after log4j has been initialized.

2. Re: Custom log4j Appender
jmoring Jun 20, 2002 4:16 PM (in response to cwstanton)Put the appender class in a standalone jar. Put that jar in jboss\lib\ext. In jboss\conf\???\jboss.conf find the org.jboss.logging.Log4jService MLET (should be the first one). Append the name of your appender jar to the ARCHIVE attribute.
Your jar = MY_APPENDER.jar
<!-- The log4j based logging service based on the conf log4j.properties file -->
This should do the trick.
