expect a slsb but get a proxy
by Heping Zhang
hi, I need a slsb so I do like this:
ctx = new InitialContext();
bean = (Calculator) ctx.lookup("favorites/UsersFacade/local");
UsersFacade is a slsb implements UsersFacadeLocal interface. however, when
it runs, I get a ClassCastException. And I find out that the looup method
actually returns a Proxy class has all the methods UsersFacade has. I am
very confused. Could someone tell me why this happen? thank you!

[JBoss Seam] - Destroying a conversation using conversation picker....
by tony.herstell＠gmail.com
cRUDUserController is a conversation scoped controller.
| @SuppressWarnings("serial")
| @Stateful // A component stays in existance for the duration of the Scope (conversation in this instance).
| @Name("cRUDUserController") // Name used within SEAM for an instance of this class.
| @Conversational // Scope that this class exists in.
|
It holds the Mode it is currently being required to "run" in and outjects this mode to the View (and this is used in pages.xml for the conversation name).
| /**
| * Bijected the mode that this Controller is currently being driven in.
| * This is used by the GUI to know how to configure the screen.
| */
| @Out
| private Mode mode;
|
Where Mode maps to an Enum:
| /**
| * The mode that this Controller is currently being driven in.
| */
| public enum Mode {CREATE, READ, UPDATE, DELETE};
|
I can swap conversations ok with the conversation picker; but I cannot destroy the conversation for the following reason:

how can I change the order of the classes handed to AnnotationConfiguration
by Heping Zhang
hi, I've got a NullPointerException at
org.hibernate.cfg.OneToOneSecondPass.doSecondPass when deplor my ejb3 app.
And I searched on the web and find out that changing the order of the
classes handed to AnnotationConfiguration may work around the problem. But
I don't know how to do it? could anyone give me some help? thanks!
