hi friends
HFSJ book says that if "type" is used without "class" ,the bean must already exist.My doubt is how to write a bean class code,so that bean is already stored as an attribute at the scope and with the "id" we have put in <jsp:useBean> tag.
anybody let me know please

thanks in advance

Write a standard JavaBean, put it in /WEB-INF/classes, and then in your JSP page, when using the <jsp:useBean> tag provide the full path of the class or import it using a page directive.

As an example, if the JavaBean was written in a package named beans, you have to say :


Make sure that your bean must have a public no-arg constructor.

Best of luck ...

In your Servlet create the bean and place it into whatever scope you choose with the id you want to use
Don't get me started about those stupid light bulbs.
