I'm migrating from weblogic (maybe). An ear file in weblogic has an APP-INF/lib directory for jarred up libraries and an APP-INF/classes directory, the contents of which eg. com/acme/MyClass.class get loaded ahead of the contents of APP-INF/lib and overide it, this very useful as it allows to test changes with having to incorporate them in a jar first.
What is the equivalent behaviour in JBoss ?
