Hi Friends,
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.

Any best practice for this kind of scenarios ?

Thanks in advance,

Thanks,
Suresh.
