Hi,

In any application if we use proxy object which was instantiated from the interface and using the same proxy object to Hibernate Api we should be able store, update or delete data.

We were able to make the Hibernate API to work with interface with some changes and implementing few other class for creating proxy object using java reflection.
We thought it is a kind good feature for hibernate to support with interfaces.

Here are steps
1.Define interface name in mapping file same as class name .
<class name="com.test.to.TestAccountBean" table="TEST_ACCOUNT">
where TestAccountBean is an interface. Rest everything in mapping file remains same.

2.Now Create a proxy object using interface, Class which generates proxy object is implemented to generate the hashcode() and equals() method for the proxy object generated from interface.

3.Now using this proxy object we can save, delete or update.

4.when retrieving values it is possible from hibernate API to identify whether it is an interface, if it is an interface then it will generate the proxy object and send back to use

5.Other than 2 new files( for generating proxy) we found that there is required to make changes at Hinernate api for these 3 file.
net.sf.hibernate.impl SessionFactoryImpl.
net.sf.hibernate.persister.AbstractEntityPersister
net.sf.hibernate.type ComponentType

If it makes sense and finds worth to be part of hinernate, we will be providing those files and changes made. As generating proxy object using interface is provided by jdk and anyone code be able to use the interface.

Looking forward for the concerned person reply.

Thanks

Looks similar to a problem I've recently posted:
http://forum.hibernate.org/viewtopic.php?t=930795

Although I require support for objects that implement multiple interfaces, each of which may provide Hibernate mappings. Would your patch solve this problem?

Cheers,
