Getting InstantiationException while using <jsp:useBean> -

-

can tell me exact meaning of type , class attributes of jsp:usebean tag.?
getting exception instantiationexception while using them in application.

an extract docs,

the jsp:usebean element declares page use bean stored within , accessible specified scope, can application, session, request, or page. if no such bean exists, statement creates bean , stores attribute of scope object .

the value of id attribute

determines name of bean in scope , identifier used reference bean in el expressions, other jsp elements, , scripting expressions .

the value supplied class attribute

must qualified class name. note beans cannot in unnamed package. format of value must package-name.class-name.

instantiation exception thrown on many scenarios, when dont specify required values attributes of usebean tag.
