ERROR Attempted to append to closed appender named [null]

[rblack]

I always get this error if I redeploy my ear and try to use my logger. My logging code looks like this:

Inside my stateful session bean's setSessionContext method:

org.apache.log4j.Logger logger = org.apache.log4j.Logger.getInstance(EmailerBean.class)

** later **

logger.debug("blah blah blah")

Any ideas why I'm trying to append to a closed appender? The hot deploy feature is really cool, and I'd like to avoid restarting the server every time I deploy.

Thanks

Has anyone else seen this?

Hi, Russell. I have the same problem. I excluded  <module name="org.apache.log4j" /> from deployement in jboss-deployment-structure.xml.
If I don't define any class in log4j.xml, then I get NullPointerException, when I write message. If I write class name in log4j, I have "ERROR Attempted to append to closed appender

['any class name'].
What's wrong?
