Hi all,
In what situation is more interesting to utilize Home and Remote Objects? Have a pattern for this.
Thanks

I dont think there is a pattern for this one. There is no need for a pattern here.

Local clients are best off using local interfaces. Remote clients must use remote interfaces.

If requirements dictate a remote business tier, then you'll need a way to communicate across that physical distribution, in which case using a session bean to access the remote business tier makes sense (Session Facade).
Remember though that distribution brings with it much complexity, so you certainly don't want to do so just because it's "interesting" ;-)
If you have a local business tier, then you can still use EJB, using Local Session beans as a Service Facade, providing transaction semantics and declarative security support.
Alternatively, if you have a local biz tier and are not using EJB, then you can use a Plain Old Java Object (POJO) Facade to coordinate access to your business objects.
We cover these issues in more detail in our book.
Thanks
