Re: [sca-j] Q about POJO introspection rules

[Mike Edwards <mike_edwards@uk.ibm.com>]

Anish,

The introspection rules take the simple
view - and it is the simple name that is used when introspecting
a class for the interfaces it implements,
not the fully qualified name.

So in your example of a class implementing
com.foo.DishWasher and com.bar.DishWasher
you'd end up with 2 service names "Dishwasher" which would cause
an error.

To solve this you'd have to annotate
the class concerned with an @Service annotation and spell out the
names that you want used.



If I recall correctly, this was debated
at the time the rules were created and the solution I've outlined was deemed
acceptable for what is a corner case
(note: the interfaces have to have @Remotable applied for any of this to
work, so it seems only a small step
to require the implementation class to have @Service applied).

Yours, Mike

Subject:	[sca-j] Q about POJO introspection rules

I was looking at the POJO spec in the context of resolving
issue 228. 
Section 8.1, line 572 of the POJO spec [1] addresses the name of the 
introspected service and says the following:

"name attribute is the simple name of the interface or the simple
name 
of the class"

Service names have to be unique within a component. In the case where 
the class implements multiple remotable interface, how does the 'simple
name' meet this uniqueness restriction?

For example, what happens if my implementation class implements two 
remotable interfaces: com.foo.DishWasher and com.bar.DishWasher. You 
can't have two services called 'DishWasher' for the same component. Am
I 
missing something OR is this a bug and "s/simple name/fully qualified
name/" (for interfaces).
