Re: [webbeans-dev] Re: Producer fields on EJBs
Carlo, Ken, Andrew,
JSR-299 supports the notion of a producer field. By adding the
annotation @Produces to a field, you make it into a bean, which can be
used as the source of injections. The field can also be associated
with a scope. When you first look up an instance of a bean, the field
value is accessed, and stored in the context for it's lifetime.
As we deal with EJB references, we can't directly access the field
value (using reflection) so I think we should use the SPI here.
I propose we add a method with this signature to the
SessionObjectReference we previously created for the purpose of
casting/removing EJBs
https://svn.jboss.org/repos/webbeans/ri/trunk/spi/src/main/java/org/jboss...
/**
* Retrieve the value of a (possibly private) field
*
* @param field
* the field to retrieve the value of
* @return the retrieved value
* @throws IllegalArgumentException
* if the field doesn't exist on this session object
instance
*/
public Object getFieldValue(Field field);
Any comments?

Ok, I would think that some language in the spec to hint at this
might be good, as instances of session beans elsewhere in the spec
implies a EJB reference.
