>             Project: Jackrabbit
>          Issue Type: Improvement
>          Components: jackrabbit-ocm
>    Affects Versions: 1.5
>         Environment: Mac OS X, Java 5
>            Reporter: Stephane Landelle
>            Assignee: Christophe Lombart
>         Attachments: ocm-proxy-v2.patch
>   Original Estimate: 1h
>  Remaining Estimate: 1h
> 1) Improvement :
> I need to be able to detect when a bean is an OCM proxy and if it has already been loaded.
This kind of functionnality is for example on Hibernate with Hibernate.isInitialized(Object
> I have developped something similar : I have modified ProxyManagerImpl so it uses an
InvocationHandler instead of a LazyLoader. This way, I make my proxies implement a special
interface whose methods are intercepted.
> 2) Bug :
> If a BeanConverter is specified, ObjectConverterImpl should pass it to the proxy CallBack
instead letting BeanLazyLoader use the default ObjectConverter. I think this is a bug, as
the behavior is different is bean property is proxified or not.
> 3) Improvement :
> If a jcrType mapped on a java type is specified, ObjectConverterImpl should make a proxy
of this type, and not use the the bean property type. This is particularly useful when the
bean property type is an interface.
> Sorry for reporting this as a bundle instead of seperate items, but I developped my patch
as a whole.  
> Let me know if you need help on the enclosing patch.
> Sincerely,
> St├ęphane Landelle
