<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">

Can any one respond to my question please

[Uppala Ramana]

Caused by: java.lang.IllegalArgumentException: Object: SampleEntity.Customer@115441f is not a known entity type.

You have to declare your persistent classes in the persistent.xml like below:

<class>com.xxx.yyy.Employee</class>

Thanks,
Ramana.
