J2EE Data layer frameworks

Question

Hi,

I am trying to figure out what are the most widely used frameworks on the data layer on a J2EE application server.

I would like help in knowing which are used out there and what are their Pros and Cons.

Thanks for the help.

Hibernate (as ORM tool) or Java EE JPA standardized API of EJB3, iBATIS (as Data Mapper Tool), or more or less raw JDBC. For more details, see previous questions like Using an ORM or plain SQL? or Hibernate, iBatis, JEE or other Java ORM tool.
