2. The following instance implements the function of passing the parameters of the first JSP page to the third page.

3. The code is as follows: 1.Jsp

What's your name

4. 2.Jsp

<%

String name = Request.getParameter ("UserName");

Session.setttribute ("UserName", Name);

%>

Your name is: <% = Request.getParameter ("UserName")%>


What's your hobby

5. 3.jsp

Your name is: <% = session.getattribute ("username")%>


Your Hobby IS: <% = Request.getParameter ("Hobby")%>


Your Password Is: <% = Request.getParameter ("pass")%>
