The command model would be satisfied by proper inheritence. Unfortunately I can't see observer being ever implementable with EJBs - basically because you can't register a bunch of listener type objects with a bean and have the bean call back to those listeners. That violates the basic principles of what a bean does and how it functions (ie potentially multiple copies of the one bean instance representing the one item of data, if we are talking about entity beans). > in Appendix A, support for component-level inheritance is cited as > an item for future releases. Yup, but we are talking about today, rather than tomorrow :) Given the current revision speed, that would be 2-3 years as a minimum before we coiuld see that sort of functionality. -- Justin Couch http://www.vlc.com.au/~justin/ Freelance Java Consultant http://www.yumetech.com/ Author, Java 3D FAQ Maintainer http://www.j3d.org/ ------------------------------------------------------------------- "Humanism is dead.
