My @OneToMany Collection<String>'s stopped working between 4

[sholodak]

Hi all,

I'm trying to upgrade from 4.0.4.CR2 to GA. I had hoped that moving my application's EAR over to the new server would just work, but it isn't. I'm getting AnnotationExceptions now stating that I'm using @OneToMany to target an unmapped class. I was under the impression that certain primitive types would be automatically taken care of and that String was on that list.

Offending Code:

private Collection<String> actions = new ArrayList<String>();

@OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
public Collection<String> getActions() {
 return this.actions;
}

Relevant Output:

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:ear=Registry.ear,jar=forms-ejb.jar,unitName=Registry
 State: FAILED
 Reason: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: [...].form.model.todo.Review.actions[java.lang.String]

I'm looking through the final versions of the JSR, but I can't find any relevant information. I've also been looking through the JBoss and Hibernate docs but haven't turned anything up yet.

Has anyone dealt with this problem / can anyone help me out with this? Do I need to make wrapper classes for these Strings so that the object in the collection is explicitly defined as an Entity?

Thanks,
Scott
