Hi,

With Jboss71, Hibernate 3, when I deploy a ejb module, jboss can't map my user-defined class to a target entity property.

Here is the error:

Change:
@OneToMany(cascade = CascadeType.ALL, mappedBy = "categorySubcategories")
private Collection<CategoryImages> categoryImagesCollection;

To:
@OneToMany(cascade = CascadeType.ALL, mappedBy = "categoryId")
private Collection<CategoryImages> categoryImagesCollection;
