I generate a war file for a grails application (grails> war) and I tried to deploy it in an external container (Tomcat and jboss).
I get 2 errors
ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by
ERROR [STDERR] log4j:ERROR [WebappClassLoader
I removed the log4j jar from the war, and I got another error :
STDERR] SLF4J: Class path contains multiple SLF4J bindings ERROR [STDERR] SLF4J: Found binding in ....
I removed the slf4j... jar from the war and it's ok, but it seems that nothing is deployed (404 not found)
I need your help, and sorry for my bad english.
