Log4j problem.

[fstarsinic]

Log4J is Great. JBoss is Great.
They work great together except when....

i want to use Log4j in my Message-Driven Bean.

since Log4j is an MBean in JBoss, my calls to log4j within my MDB do not find Log4j.

So my only options that i see are
Don't use log4j
comment out the mbean in jboss.conf for log4j
and inlcude it in my classpath before starting
jboss.

is there another solution?

thanks,

frank

Hi Frank,

We have used log4j in our beans and web classes. We extend the category class to provide our own. This causes class cast exception when redeploying due to JBoss's use of log4j. To get around these issues we ended up putting the extended category in a jar on the classpath (lib/ext) so that it was not redeployed each time, thus no class cast.

Also, and more specific to your question is you can add a line into the jboss.conf file for the log4j service to direct it to another config file. We have





to use the log4j-config.xml file as the log config file instead of the log4j.properties used by JBoss. This means that it picks up your config file and your settings, which should sort out your problem

I get class not found errors whenever I try to get the logger.
java.lang.NoClassDefFoundError: org/apache/log4j/Logger

I assume this is because the classloader for my ejb is different from the one used to create the log4j JMX MBean.
How did you get around this

Logger is in log4j 1.2 (still beta)

JBoss uses log4j 1.1

Ok I got it to compile however the followin config file doesn't produce any log files

# default JBoss ConsoleLogging & FileLogging mbeans.
