Java JSP and Servlets Calling a JavaBean from a JSP Page Tutorial
In the earlier article, What are JavaBeans? , we learned what are JavaBeans and we even created a simple JavaBean class file; SimpleBean. We will be using this SimpleBean class in this tutorial, so if you haven't read above article then I suggest you do it now. Before we continue to describe how to code a JSP page to call that JavaBean, let's first discuss the three JSP tags provided to us to make use of JavaBeans.

This tag is used to declare and instantiate the JavaBean class. It's syntax is as follows : <jsp:useBean
id="object-name"
scope="page | request | session | application"
type="type-of-object"
class="fully-qualified-classname"
beanName="fully-qualified-beanName"
/>
Let us now see what are the different attributes :
id - name of the object e.g.
String name = null; In the above code, name is the 'id' we are talking about.
