EJB and pattern

[Timber Lee]

EJBHome – Abstract Factory or Factory Method ?
EJBObject – Decorator or Proxy ?

[Ajith Kallambella]

IMHO
EJBHome - Abstract factory.
EJBObject - certainly not a proxy. Actually a wrapper, not a decorator.

[Thomas Hofmann]

EJBObject is a decorator

[Timber Lee]

what is mainly different between proxy and wrapper?

[Timber Lee]

if the functions contributed by contained, such as security, transaction, are considered, ejbobject is like decorator pattern

[Debanjana Dasgupta]

The RemoteInteface is Proxy
Thanks

A proxy provides the same interface as the remote objects. Though the (container generated) stub on the cilent side is a proxy for the remote object. The client communicates only with stub. "Behind the scenes" the stub establishes all network stuff (opening socket to remote server, marshalling parameters, ...). The stub which implements the remote interface is the proxy for the EJBObject, not the interface itself.
