Am using Hibernate 3 / JPA on Java 6. Am trying to fetch a simple row from the database (which is populated).

Created the following JPA Annotated Domain Object:



My hibernate.cfg.xml file:



Code snippet from calling class:



When I run the calling class, this is the exception I get:



Line 15 where this ClassCastException occurs is here:



Here are my dependencies:



What I am I possibly doing wrong? I just want to call a simple select query against a person table.

What is the most simplest way to do a select query for one row of my Person table in Hibernate / JPA?

I am using session factory instead of entity manager.

Thank you for taking the time to read this.

Hi
Can you try two things
1) use query.list() instead of query.getResultList()
2) also instead of session.createQuery("SELECT p FROM Person p"); you can try session.createQuery("FROM Person");
