Q: 

JPA and hibernate for Flex

I'm using JPA but I'm not sure how to use it for relation between two classes. I need to connect them @OneToMany. I have done this before but forgot. Is there any good tutorial for this or an example that is easy to understand.

By the way this is a Flex application where I'm using BlazeDS for connection between Java and Flex.

+1  A: 

Have a look at the Introduction to the Java Persistence API in The Java EE 5 Tutorial and more precisely the section on Multiplicity in Entity Relationships.

I have already seen this. But what I need is an example or tutorial for how to write the code correctly.For the moment I'm not sure about how to map @OneToMany ??? With what class???

@dejaninic There are two examples in the tutorial (http://java.sun.com/javaee/5/docs/tutorial/doc/bnbrt.html and http://java.sun.com/javaee/5/docs/tutorial/doc/bnbsw.html). Without details on your object model, it's impossible to provide more guidance (how could readers tell you how to map your classes if you don't say anything about them?).
