If JPA is specification, how can we use it?

[jagrutkumar dalwadi]

Can you anyone suggest how can we use JPA in Project, as it is just specification not implementation like Hibernate or Toplink?

[Hussein Baghdadi]

You can use JPA the same way you can use JSP, Servlets or EJB.
The specification defines the interface/contract and the developers implement those specifications. Tomcat implements JSP and Servlets specifications. Hibernate and TopLink implement the JPA specification.
