Description

I was trying to configure JDBC fail-over, so I put my mysql driver jar in the KARAF_HOME/lib directory. I kept getting ClassNotFoundExceptions. On the advice of someone on IRC, I changed the name to "karaf-mysql-connector-java.jar" and it started working. Why the karaf- prefix requirement? If that's the intended behavior, then please update the README file in the lib directory. It says:

"Any jar in this folder will be part of the main classloader used to load Karaf."
