To view the discussion, visit: http://community.jboss.org/message/562182#562182 -------------------------------------------------------------- Hi, I have an existing J2EE application without any dependency injection, so if class A uses class B then in class A I have public class A {}     . . .     B b = new B();     b.doSomething();     . . . } and if I want to sobstitute B with C (which extends B) I have to modify class A. I don't want to modify the entire application but I'd like to intercept class loading in order to replace on the fly class B with class C. Is this possible in JBoss? Can I replace the class loader with a custom one? Thanks in advance, Andrea  -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/562182#562182] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
