Invalidating session in struts2
When we create a customer, we create the books as well and if we delete the customer ...................... EAGER defines that if we select a customer all books borrowed by this customer are loaded as well.
you are wrong when you think that the books will be deleted. I used cascading here for ease when creating test data. The reason is that EJB 3 does not allow loading of data when your current persistence context is closed.
I would remove this attribute in your Log Out User Action but don't invalidate the session.

Add the following constructors and implement the to String method. Domain objects are things like Address, Book, Customer in contrast to business logic like Mail Factory, Authorize Filter. Now, we will add the annotations: Entity defines that this is an entity bean. For example a language table and the primary key is the ISO-Country code id: EN, DE, FR, ....
Use a sequence for Postgre Sql, Sap Db, Oracle and other . It returns the next Integer or Long value each time it is called. I am using Postgre Sql, so I defined the sequence first in Order to use it later for my primary key. Here is one solution that always works: It safes the primary keys in a separated table. Define it in front of your class: Important generator = "book_id refers to the name defined in front of your class @Table Generator( name="book_id" Repeat the steps explained for the books.
