I am facing the same issue. Hornetq 2.2 had Log4jLogDelegateFactory which allowed configuring log4j for logging. But in hornetq 2.3, there jboss logging framework is configured by default and I am not able to find a way to configure log4j. Please advise.
HornetQ 2.3.0 is now using JBoss Logging, as it was a requirement for JBoss7.
I know JBoss Logging has that capability, but you would need to check on jboss logging docs.
I will see if I can find something myself and will put a note here.
