Hello, everybody!
My project has functionality which is pretty generic, and I'd like to reuse it in another project.
In other words I'd like to have a jar file which defines several interfaces/classes and maps then to database tables.
Later, when add this jar to another project which also has hibernate mapping, both mappings should be merged together.
In ideal case I'd like just add jar to class path, but some configuration/initialization is Ok.

What would be the best way to do it?

Thank you,
Andrey

I guess I have to clarify my question. Let's say I have two entities:

interface User{
long getId();
String getName();
}

@Entity
class Something {
@Id
long id;
@ManyToOne
User user;
}

I want to use interface because I don't know the concrete implementation of User interface. I want to ship these two classes as library (jar file).

Later I want to add this jar to another project which has implementation of User:

@Entity
class UserImpl implements User{
@Id
long id;
String name;
...
}

At this moment I expect Hibernate to build ManyToOne relationship between Something and UserImpl.

Any ideas how to achieve this?

Thank you,
Andrey
