HI,

I am new to Hibernate and i am tying to build a sample Hibernate application using the one given at http://www.laliluna.de/download/struts-hibernate-integration-tutorial-en.pdf

I am using eclipse to build this project.

I am having to tables, viz. book and customer. I have written a test code to save each of these objects in the DB.

The entity mapping files are similar, as mentioned in the tutorial.

But when I try to save these objects using session.save(),
I am getting the following exception


Can please anyone guide me on this.

Sounds to me like the Book class isn't mentioned in the configuration file. You're using mapping files, right? Each Java class that acts as an entity must be mentioned in the mappings section of the configuration file.
