    [ https://jira.jboss.org/jira/browse/JBIDE-2077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12431205#action_12431205 ] 

Vitali Yemialyanchyk commented on JBIDE-2077:
---------------------------------------------

>>
#5 if I have a public Product(String name) constructor a default protected constructor is not created - that should happen should it not ? 
>>
as I understood in this case we should add Serializable interface - for example
from this ->
org.hibernate.eclipse.jdt.ui.test\res\project\test\annotated\Staff.java
we should get this ->
org.hibernate.eclipse.jdt.ui.test\res\specimen\test\annotated\Staff.java

>>
#5 stop doing "reverse if" comparisons, #6, #7, #8, #9, #11
>>
ok, I am tying to avoid this - 5 - this is just automatically
9 - 1&2 are necessary here - I'll change number constants to flags with reasonable names

>>
9 - Do we really have to keep track of all those imports this way? 
>>
seems this is a most robust way

>>
#10
>>
seems - org.hibernate.eclipse.jdt.ui.test\res\project\lib\ejb3-persistence.jar - this is file out of the patch


"the tests fail with differences" - strange, I have got correct result - I'll try to apply it on other computer to check results...

> 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.
