The <bean:define> tag differs from <jsp:useBean> in several ways,
including:
* Unconditionally creates (or replaces) a bean under the specified
identifier.
* Can create a bean with the value returned by a property getter of
a different bean (including properties referenced with a nested
and/or indexed property name).
* Can create a bean whose contents is a literal string (or the
result of a runtime expression) specified by the value attribute.
