You create dynamic content by accessing Java programming language objects from within scripting elements.
You can access a variety of objects, including enterprise beans and JavaBeans components, within a JSP page. JSP technology automatically makes some objects available, and you can also create and access application-specific objects.

Many of the objects are defined by the Java Servlet technology underlying JSP technology and are discussed at length in Chapter 10. Table 11-2 summarizes the implicit objects.
