Hibernate / EclipseLink Interview questions

What is EclipseLink DBWS?

DBWS (Database Web Services) generates web service interfaces, complete with WSDL, directly from database artifacts like tables, views, and stored procedures, without requiring an application to define Java entity classes or hand-write service code first.

It's aimed at scenarios where the fastest path to exposing legacy database logic as a service matters more than building a full domain model: point DBWS at a set of stored procedures or tables, and it produces a deployable web service that maps incoming requests to the underlying database operations automatically.
