I am trying to create a simple application in which,
1) index.html -> index page takes a name and passes it to
servlet
2) control.java (servlet) -> takes the parameter from index.html , and creates a javabean and set that value into the bean and than finally set the bean as a request attribute, and forward the request to result.jsp
3) person.java (
java bean) -> person.java is an java bean having property "name" and getter setter method
4) result.jsp -> this
jsp files tries to read the bean value using <jsp:useBean> and <jsp:getPropert> tags.
My application runs perfectly upto servlet and servlet also passes the control to jsp. But in result.jsp a error comes given below.
Note : control.class and Person.class file are stored inside web-inf/classes
An error occurred at line: 13 in the jsp file: /result.jsp
Person cannot be resolved to a type
10: Person is <% //Person p = (Person) request.getAttribute("person");
11: //out.println(p.getName()); %>
12:
13: <jsp:useBean id="person" class="Person" scope="request" />
14: <jsp:getProperty name="person" property="name"/>
15: </body>
16: </html>
