A Java Bean is nothing more than a Java class that follows a set of
naming conventions for its methods, e.g. getFoo and setFoo means the
Bean has a read/write property named foo. These simple conventions
make it possible for tools to understand what properties a Bean has,
and for instance provide GUIs to access the property values.
Optionally a Bean can provide a set of methods and some more stuff to
allow visual tools to use a customized property sheet for a Bean.
So, yes JSP uses Beans in the <jsp:useBean>, <jsp:setProperty> and
<jsp:getProperty> actions but there are no GUI based JSP tools available
at this time (as far as I know). In the future web authoring tools may
provide GUI based tools for customizing the Beans as well, but that's pure
speculation at this point. Writing a Bean is simply to follow the naming
conventions.
