尝试将值从servlet传递到jsp页面

Question

I'm trying to pass a value from a servlet java page to a jsp page, by using session. Here is my code on the servlet page.

session.setAttribute ( "SPONSOR_ID", loginSponsorID ) ;
request.getRequestDispatcher("summary.jsp").forward(request, response);

And here is the code on the jsp page

This prints null value: <%=request.getAttribute("SPONSOR_Name")%>.

I get errors when I try assigning the return value into a variable.

<c:set var=intMethod value"${'<%=request.getAttribute("SPONSOR_Name")%>'}"/>

Answer 1

I think you have typo, you set value in session but trying to read from request. make these two calls in sync, use either session or request.

Answer 2

Hopes this is the problem; You have setted SPONSOR_ID and trying to retrieve SPONSOR_Name.

HttpSession session = request.getSession(true);
session.setAttribute("SPONSOR_ID", loginSponsorID);

and in JSP

<%= session.getAttribute( "SPONSOR_ID" ) %>
