See if you are still writing applications that use
data-aware GUI components to interface directly with the
database, you might want to reconsider. Applications built
in this manner are not object oriented. Such two-layer
(GUI/Database) applications violate one of the primary
principles of object-oriented design: encapsulation.
Encapsulation is what allows a client to interact with an
object without knowledge of its implementation details, a
primary premise for loose coupling. In applications that use
data-aware widgets, the opposite is the case. The client and
the database are very tightly coupled. GUI code, business
logic, and SQL statements are all interwoven throughout the
application source code. As a result, the application can
become a maintenance nightmare. Any changes in the database
schema will surely cascade into unexpected failures.
Thats why we design a J2EE application so user data is
entered by way of a JSP page and managed by an underlying
Java Beans class

Its always better to seggregate/seperate the duties of
components. Its correct way to implement MVC architecture.
JSP takes care of View Component and Bean Object will be
used as Transfer Object in application.

As per my understanding, Java Bean exposes the properties
of the JSP page in a consistent way.
Also it represents the jsp page as a simple java object
(POJO) which is having certain state. and it is easy to
handle java beans.
