I am trying to get log4j working with a very simple
session bean in weblogic 7.0. The bean works fine if
I comment out all of the logging code. If I leave the
logging code in I get this exception:

Here is all of the pertinent information I can think
of:
The manifest for the EJB JAR:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.5.3
Created-By: 1.3.1_07-b02 (Sun Microsystems Inc.)
Built-By: Jerry Cattell
Built-On: 2003-06-14T06:13:20
Class-Path: log4j-1.2.8.jar
The files in the EAR:
META-INF/MANIFEST.MF
test-ejb.jar
log4j-1.2.8.jar
log4j.properties
META-INF/application.xml
The files in the JAR:
META-INF/MANIFEST.MF
test/ejb/NetworkServerBean.class
test/ejb/NetworkServerSession.class
test/interfaces/NetworkServerLocal.class
test/interfaces/NetworkServerLocalHome.class
test/interfaces/NetworkServerRemote.class
test/interfaces/NetworkServerRemoteHome.class
test/util/NetworkServerUtil.class
META-INF/ejb-jar.xml
META-INF/weblogic-ejb-jar.xml
If someone can see what I'm doing wrong, I would
greatly appreciate it.
Thanks,
Jerry
