Hibernate and Spring Annotation @OneToMany unmapped class error

Question

I'm using Spring 3 with Hibernate 3 and getting this error:

Caused by: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: cz.dagoo.dros.models.Invoice.invoiceItems[cz.dagoo.dros.models.InvoiceItem]

I've tried everything what I found but I'm not able to solve this problem.

How is it possible that some class is unmapped?

Invoice class:

InvoiceItem class:

Hibernate.xml:

BeanLocations.xml:

My project files:

As the exception tells you: cz.dagoo.dros.models.InvoiceItem is not mapped as an entity. To solve this issue you should add the missing @Entity-annotation on InvoiceItem.
