JavaBeans are Java's answer to Microsoft's ActiveX components. A JavaBean is the architecture for using and building components in Java. A bean can be either a visual object�meaning you can change the properties of a component by changing a radio button or similar object�or a nonvisual object. Rather than show you how to build JavaBeans (which could be the subject of an entire book), this tutorial will show you how to integrate JSP with a preexisting bean.
