Steve,
I would say that the term 'JSP Bean' is useful and would disagree with
Jann's statement that 'beans is beans'. The beans that are typically used
in JSP pages are used on the server side and not on the client side. They
are not typically configured using a GUI tool and are not stored in
serialized form. Beans in JSP pages are typically used as value objects to
store related pieces of data or to encapsulate functionality in a reusable
package. JSP beans don't use any of the classes in the java.beans package
as the other JavaBeans might use. JavaBeans, on the other hand, are
sometimes written to operate in different design-time and run-time
modes. At design-time the component provides information necessary to edit
its properties and customize its behavior. It also needs to expose methods
and events so that a design tool can write code that interacts with the
bean at run-time.
The main similarities between the two are that the both adhere to the
design pattern of using getter and setter methods for accessing member
variables.
