jsp and getting attributes data

Question

I am trying to display the note attribute that I saved into my request.setAttribute("entries", entries), but I can't access this data in my jsp and I can't figure it out. I've tried {note} , but that doesn't work.

This is my controller class:

                while( rs.next() )
                {
                        int id          = rs.getInt("id");
                        String name     = rs.getString("name");
                        String note     = rs.getString("note");
                        String title    = rs.getString("title");

                        Notes entry = new Notes(id, name, note, title);
                        entries.add(entry);
                }

                request.setAttribute("entries", entries);

                request.getRequestDispatcher( "/WEB-INF/homework2/MyNotes.jsp" ).forward(
                     request, response );


            }
            catch( SQLException e )
            {
                throw new ServletException( e );
            }
            finally
            {
                try
                {
                    if( c != null ) c.close();
                }
                catch( SQLException e )
                {
                    throw new ServletException( e );
                }
            }


        }   

}

This is my jsp view:

    <br>
    <br>
    <br>


   <p>${note} </p>
    <p>${applicationScope.entries.note},</p>

    </body>
    </html>

you can try with this , ${param.entries} or ${requestScope.entries} — Vishal Gajera, Nov 30 '15 at 11:18

You already have your List in your request so:

Then you can, (for example) put info a table:

<c:forEach items="${requestScope.entries}" var="entry">
    <tr>
        <td>ID: <c:out value="${entry.id}"/></td>
        <td>Name: <c:out value="${entry.name}"/></td>  
        <td>Note: <c:out value="${entry.note}"/></td>
        <td>Title: <c:out value="${entry.title}"/></td>  
    </tr>
</c:forEach>

yeah this is how i initially did it , but it returns all the notes. i only want 1 note to display. – user3225981 Dec 01 '15 at 02:41
mmmm,... just 1 note? which one? first? last? matching any condition? why are you passing a list and not a single entry in the request then? let me know and I will edit my answer accordingly ;) – Jordi Castilla Dec 01 '15 at 09:26
