[jboss-user] [Installation, Configuration & DEPLOYMENT] - jboss && log4j

[Darkshine]

I'm using jboss with log4j. I have remote application jmslistener, which uses jboss over network. When I try to start jmslistener, I get the following errors:

log4j:ERROR Error while activating options for appender named [DefaultAppender].

It looks like I missed some jar-files in CLASSPATH. Is this true?

My CLASSPATH contains the following jars:
jta20.jar
log4j-1.2.13.jar
oalnf.jar
jbossall-client.jar
jboss-j2ee.jar

My jboss is:
jboss-eap-4.3

Thanks
