Debug level Hibernate log excerpt:


I have a POJO that is mapped to a database table. I am passing this POJO from the EJB layer to the web-tier. The web-tier updates the POJO model object and sends it back to the EJB to persist. Everything works fine until this.

Now, the web-tier needs to put some *extra* information into the POJO model object. For this, I need additional fields in my POJO. Can I add additional fields to my POJO class without affecting Hibernate?

Any help is appreciated.

of course you can add calculated/non persistent business fields in the pojo... what is the problem? these fields won't be declared in the mapping file... that's all
