"Make this class and its related classes mapped via JPA"
--------------------------------------------------------

                 Key: JBIDE-2077
                 URL: http://jira.jboss.com/jira/browse/JBIDE-2077
             Project: Tools (JBoss Tools)
          Issue Type: Feature Request
          Components: Hibernate

            Priority: Minor


Denis Golovin:
>>>
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.
