[jboss-user] [JBoss Seam] - log4j error in Tomcat 6
I'm seeing this NullPointer error when I shutdown Tomcat 6.0.13:

I'm using the following log4j config file just as I found it in the JPA (tomcat pojo)
example in Seam 1.3.0 ALPHA:

I'm using the exact same library set from the JPA example except the two el-*.jar libs
(wouldn't run with those in place).
The application seems to work fine, it's just the exception on shutdown makes me
nervous.
Is this an indication of trouble elsewhere? Any suggestions on how to make it go away
would be very much appreciated.
Thanks!
