Redundant information in JSP bean action

Question

Class Person:
public class Person{
private String name;
public void setName(String p){
name=p;
public String getName(){
return name;
}Code in servlet:
public void doPost(HTTPServletRequest request, HTTPServletResponse response) throws IOException,ServletException{
foo.Person p= new foo.Person();
p.setName("New Guy");
request.setAttribute("person",p);
RequestDispatcher view = request.getRequestDispatcher("result.jsp");
view.forward(request,response);
}Code in JSP:
<jsp:useBean id="person" class="foo.Person" scope="request">This jsp:useBean tag really is confusing. Why does it need to declare the class="foo.Person"? Why does the JSP need to know that "person" instance is derived from class foo.Person ? (I wonder if I changed this to foo.person --> not Person will result in error). Doesn't the statement request.setAttribute("person",p) from the servlet give enough info already to the JSP? thanks

Answer 1

The "person" in your servlet has nothing to do with your "person" in your JSP bean tag.
