I am new to hibernate and I want to use it on a swing application. However I keep getting this: Exception in thread "AWT-EventQueue-0" org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: store.management.models.Invoice.sales[store.management.models.Sales…

You forgot the @Entity annotation on the Sales class. Instead of this: public class Sales { ... do this: @Entity @Table(name="Sales") public class Sales { ...

You might get the same error even if your class is all correct - you might have forgotten to register it in persistence.xml file as class element…

Thank you Maris. I had the same issue, I have forgotten to register my Entity in persistence.xml file.
