The introspection process allows the JSP engine to populate a JavaBean with the values provided by a client through an HTML form.
//when the names of the bean properties match the names of the HTML //form<jsp:useBean id="bean_name_here" class="bean_class_here" scope="page|request|session|application"> //when the names of the bean properties don't match the names of the //HTML form
This technique is very useful if you want to manage an HTML form through a JSP page.
