Guys,

What is the need for orm.xml and persistence.xml files?

  • persistence.xml defines the identities and configuration properties of persistence units;
  • orm.xml is optional and defines the mapping between classes and persistence units.

    If I do not provide an orm.xml file, then the persistence provider will automatically map my POJO's based on the metadata annotations that I have. Am I right in this sense?

    exactly!

    and if you have both, xml overrides the annotations.

    If I were to relate this with Hibernate, a persistence.xml is something like a hibernate-cfg.xml and the orm.xml is like a mapping xml that we have in Hibernate.
