> Let's imagine I have several (say 10) classes that I'd like to make
> persistent. The classes form completed domain model.
> I decided to use hibernate and JPA annotations, I have lets say JBDS
> 1.1.0 or JBossTools 2.1.0 installed.
> Question is what I should do to make my model persistent? It there
> anything that helps me to do it?
> Now I see only way. I have to go through all classes and add annotations
> for class and for fields.

> Having a "Make this class and its related classes mapped via JPA" would be 
> an interesting Refactoring to implement.
> Should basically just work like this:
> makePersistent(ITypeRoot clazz, Set processed) {
>   add @Entity 
>   Find most likely id property and add @Id  
>  processed.add(selectedClass);
>  associations = getAssociatedClasses(selectedClass);
>  foreach class in associations {
>   if(!processed.contains(class)) {
>        makePersistent(class, processed);     
>   }  
> }
> }
> There then might be some exceptional cases like handling version properties, temporal values and
> non-JPA supported mappings which Hibernate would be able to understand/map.
