This is not just a question about hibernate use but about its cool architecture. This is my problem:

I am a java programmer and I need to create dynamic proxies for my business objects. Java reflections facilities permit solve this problem but only when business object implements a set of interfaces (by creating a class implementing java.lang.reflect.InvocationHandler and using the factory method java.lang.reflect.Proxy.newProxyInstance).

I have posted this question in other forum obtaining no response but I know that Hibernate architecture solve exactly this problem. A persistent business object managed for hibernate and delivered to the programmer is not a real business object but a proxy implementing, among other things, lazy initialization logic for collections.

Please somebody could tell me how Hibernate creates dynamic proxies for objects implementing no interfaces?

Thanks in forward.

Hi

Take a look at the following http://www.hibernate.org/hib_docs/reference/en/html/performance.html#performance-fetching-proxies. The Hibernate proxy is actually a subclass of the persistent class, which it creates using CGLIB. CGLIB is probably what you want to be looking at, a good primer is here http://www.ociweb.com/jnb/jnbNov2005.html

I hope this helps
