    @Id

private String name;
@ElementCollection(targetClass = S         


        

Answer 1

Aah I see, its a . I dont think you can map a primitive unless you are using latest jar. https://forum.hibernate.org/viewtopic.php?t=955308. Check that link. Could you make a class called as Properties with key and value and then use it? I had a similar problem and I had to use that approach.

Answer 2

Shouldn't properties just be a List<String> type?

It sounds like Hibernates confusion is the same as mine which is, why is Properies a Map instead of a list? What exactly are you trying to do there?

Answer 3

I also face the same problem.It is late but i think it will help others.use @MapKeyColumn.here is my simple code

@ElementCollection(targetClass=String.class)
@MapKeyColumn(name="Employee_Position")
private Map<String,String> position=new HashMap<String,String>();

Answer 4

Do you have both getter and setter for Properties?

Answer 5

that's because you have to use some jpa2 implementation! this guy had the same problem
