Servlet Context and Servlet

Sudhanshu Mishra wrote:Thanks Pravin,
So may i conclue that the servlet is created after the servlet context has been created,and hence a listener class(ContextLoaderListener) will run before a servlet(DispatcherServlet)?

Thanks.

how to print values on jsp page fetched from servlet

Piyush Mangal wrote:Hi Pravin, Please find below the sample code. Please note that this is not complete code and is only for your understanding.

JSP

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <html> <head> <title>Simple JSP</title> </head> <body> <table border="1" > <tr> <th>Name</th> <th>Secn</th> <th>Title</th> </tr> <c:forEach var="row" items="${rows}"> <tr> <td><c:out value="${row.name}"/></td> <td><c:out value="${row.secn}"/></td> <td><c:out value="${row.title}"/></td> </tr> </c:forEach> </table> </body> </html>

Servlet

public class Controller extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Model> results = getAllModels(); // getAllModels returns list of Model objects //request.getSession().setAttribute("rows",results); request.setAttribute("rows",results); RequestDispatcher dispatcher = request.getRequestDispatcher("/display.jsp"); if (dispatcher != null){ dispatcher.forward(request, response); } } } public class Model { private String name; private String secn; private String title; ------- --- }

thank you, Piyush :thumbup:

All I am saying is that the above code is incorrect and redundant. You can always set attributes in session scope through your controller and dispatch the request to JSP.

thank you, i understand it now :)

If the scoped variable Name is present in request scope, it can be displayed with one of:

${Name}

or

<c:out value="${Name}"/>

depending upon whether HTML-encoding is needed or not (to protect against XSS attacks).

No <c:set> tags are needed.

thank you. now i understand :)

<td><c:out value="${name}"/></td> <td><c:out value="${secn}"/></td> <td><c:out value="${title}"/></td>

Ideally Servlet should be responsible for setting the attribute in Request or Session scope based on the use case and forward the request to jsp.
JSP should only use EL to display them on screen.

would you be able to come up with other ways of doing this?
