Hi there,
I've been rummaging around here for a few hours trying to figure this out.
We have a web application that has been developed as a "universal" WAR file. This means that the same WAR must deploy and run on the three …
[View More]application servers that we support, including JBoss 5.1.
This webapp contains both a log4j implementation and an slf4j implementation. This results in the following errors when the application is started:
2012-02-01 17:30:08,327 ERROR [STDERR] (HDScanner) log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
2012-02-01 17:30:08,329 ERROR [STDERR] (HDScanner) log4j:ERROR The class "org.apache.log4j.Appender" was loaded by

2012-02-01 17:30:08,364 ERROR [STDERR] (HDScanner) SLF4J: Found binding in [vfszip:/Users/steve/servers/jboss-eap-5.1.1/server/axelerator-platform/deploy/axelerator-platform-mr-web-12.1.1-SNAPSHOT.war/WEB-INF/lib/slf4j-jdk14-1.5.8.jar/org/slf4j/impl/StaticLoggerBinder.class]
We prefer to use the JBoss provided implementations of these as this simplifies logging configuration for administrators.
Therefore, I'd like to know if it's possible to filter out these two jars from the classloader so that they're effectively ignored in our JBoss deployment.
And if so, how do we go about it?
Thanks
