Hibernate Tools does not support ElementCollection ?

[nimo22]

I have something like this:

@ElementCollection
      @CollectionTable(
            name="PHONE"
      )
      @Column(name="PHONE_NUMBER")
      private List<String> phones;

within an entity. The Tables are all successfully generated by JPA (Hibernate).

However, when opening the Hibernate Tools SessionFactory, I get this error:

"Could not determine type for java.util.list for table, at table MY_TABLE, for columns: [org.hibernate.mapping.Column(PHONE_NUMBER)]"

Does this error come from Hibernate Tools or Hibernate ? Hibernate still generates this tables without complaining. But Hibernate Tools complains.

Do you have a stacktrace for this error?

[nimo22]

Unfortunately not. There is not stacktrace when compiling and deploying the application. The ElementCollection is working.

Only when opening the HQL-Editor the error comes. I go to "rebuild configuration". Then the branch of configuration, session factory and database is opened. The error is displayed in the SessionFactory branch:

"<SessionFactory error: Could not determine type for java.util.list for table, at table  MY_TABLE, for columns: [org.hibernate.mapping.Column(PHONE_NUMBER)]"

How about this one:
