Our project is using EJB3, JPA .I need to perform common operation (picking up data based on some criteria) across all JPA entities. I would like to isolate that logic in a base bean and all the other beans extends this base bean.
But challenging is that, I need to know the Entity instance name, and as well as the column names in the particular entity. Column names are varying from entity to entity.
