ResultSet, Statement, HttpServletRequest/Response etc. Many of these are stated as Classes in O'Reilly while Wrox books states them as Interfaces. Checked with the API which goes alongwith Wrox. Are the O'Reilly books "Really" this negligent or r there some other reasons?

Maybe they are referring to the underlying class that is implementing that interface. For example, if you have a java.sql.Connection, Connection is an interface, but you do have an instance of some class that is implementing the interface.
Its probably just a question of semantics.

Why don't you give us a direct quote from the O'Reilly book where you think they made a mistake.
