How to use beans in JSP?

Submitted by: Administrator

Java Beans are reusable components. They are used to separate Business Logic from Presentation Logic. Internally a bean is just an instance of a class. JSP’s provide three basic tags for working with Beans.

* <jsp : useBean id="bean name" class="bean class" scope= "page | request | session | application " />

bean name = the name that refers to the bean.

Bean class = name of the java class that defines the bean.

* <jsp:setProperty name = “id” property = “someProperty” value = “someValue” /

id = the name of the bean as specified in the useBean tag.

property = name of the property to be passed to the bean.

value = value of that particular property .

* <jsp:getProperty name = “id” property = “someProperty” />
