I am doing a JBoss SEAM project and when I view a form I get this error.
java.lang.ClassCastException:
it.cogitoweb.csi.entity.csiorelav.CsiTipoLav cannot be cast to
it.cogitoweb.csi.entity.csiorelav.CsiTipoLav
Its alway the same JPA class which is related to the form which is shown on the screen, it doesn’t make sense to me why is it the same class, it seems impossible.
This happens when two different
ClassLoaderobjects load classes with the same name. The equality of two classes in Java depends on the fully qualified name and the class loader that loaded it.So if two independent class loaders load classes from the same location, then objects of those types will not be able to be cast to each others type, even if their classes are called the same.
