EJB allows for several EJBs to have the same home an remote interface.
Actually you can have several EJBs with the same interfaces and
implementations. I have seen this used in applications where the same
EJB is deployed multiple times (under different names) with different
locking policies.

if the ejb-ref maps to the home and remote interface, what would be a scenario where we could have amibuity?
Right now , i cant think of a situation where we could have two different matches for an ejb-ref. Could you
please clarify that?

No, and ejb-ref contains the name of the home interface and remote
interface (or local and local-home). Here is an example from one of my
files:
<ejb-ref>
<ejb-ref-name>foo</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>org.acme.FooHome</home>
<remote>org.acme.FooRemote</remote>
</ejb-ref>
So we match using the two interfaces

The goal is to not have geronimo dd for simple cases. If you had a
geronimo dd, you could either us the target-name (JSR 77 object name of
the ejb) or an ejb-link.

Thanks Dain,
How will the match be determined? is the ejb-ref name going to match the
home interface name?
Is it possible that to remove ambiguity, we could make an entry into the
geronimo dd where we could map the ejb-ref with a fully qualified name
of the home interface.

Some applications like Petstore (at least the version Rajesh used)
don't have ejb-links so you have to resolve the reference by hand (a
total PITA). As a last resort the deployment code can search the ear
for an ejb with a matching home and remote interface. Assuming we only
find one matching ejb, we will use that one for the ref. If we find
two or more matches, you would get an AmbiguousEJBRefException, and if
we find none you would get a DeploymentException.

Some applications assume that ejb-refs can be resolved by matching on
interface types.
What does this mean?
