<h3>Introduction</h3>
<p>Much of the power of JavaServer Pages (JSP) technology comes from the
simple and powerful mechanisms by which the servlet that is generated automatically
from your JSP source page can interact with JavaBeans that represent the computational
state of your application. In standard JSP pages, the <code><jsp:useBean></code>
tag is used create a bean (if necessary), as well as a "scripting variable"
that can be used within scriptlets to refer to these beans.</p>
<p>The "struts-bean" tag library provides substantial enhancements to the
basic capability provided by <code><jsp:useBean></code>, as discussed
in the following sections:</p>
