Thank you

i am eager to try this out

Hi Bate,
this error seems related to your other question: the EntityManager will auto-discover entities from the classpath containing the META-INF/persistence.xml, but since it didn't find them it seems your project configuration is not correct.
If I import this as a new Maven project either in IDEA or in Eclipse, running the application works fine (I didn't try other IDEs, but it should work all the same provided they have good Maven support, like Netbeans should work fine too).
