I have a piece of code  in a  controller which  has a  method to display the list of item
 from the data base  i.e i could see the data in the sop but not able to display the data
in the jsp .  

 what could be the reason...

Thank you
 java code
//Display listExistingRights(/) 
	@RequestMapping(value = "tile/list")
	public ModelAndView existRights
	( Model model, HttpServletRequest request) {

		List<WebdUserRight> maintainrights = new ArrayList<WebdUserRight>();

		EntityManager em = DataAccess.emf.createEntityManager();

		try {
			maintainrights = WebdUserRight.findAll(em);
			model.addAttribute("maintainrights", maintainrights);
			for (WebdUserRight rights : maintainrights) {
				System.out.println("rights: " + rights.getCode() + ", drsc: "                                          +  rights.getDescrip());

		} finally {
		return new ModelAndView( "tile/mainRights", "maintainrights", maintainrights);

Open in new window

in jsp i use

    <c:forEach var="rights" items="${maintainrights}" varStatus="idx">
		<tr data-right-id="${rights.code}" >
			<td style="width:30px;text-align: center;">
        	    <img class="addEditRights" style="cursor:pointer;" src="/asset/image/silk/edit.png" />

Open in new window

on click event when i call  the above jsp page it donot display anything

$( "#MaintainRights").click( function() {

document.location.href = "/tile/mainRights.html?maintainrights="+maintainrights;

Open in new window

you should call your controller and in turn it will redirect to the jsp page..

see this example

call the servlet like this.



public class MemberController

    public ModelAndView registerNewMember()
          List<Member> maintainrights = new ArrayList<Member>();
          Member m = new Member();
          m.setId(new Long(1));
          Member m1 = new Member();
          m1.setId(new Long(2));

          return new ModelAndView( "index", "maintainrights", maintainrights);


      <c:forEach items="${maintainrights}" var="member">
                                                            <td><a href="<c:url value="/rest/members/${}"/>">/rest/members/${}</a></td>

apart from that you cannot send the object in the url

$( "#MaintainRights").click( function() {

document.location.href = "/tile/mainRights.html?maintainrights="+maintainrights;

There is no problem with the controller sending to the jsp.. As with the debug i could see the  value... but  i think the issue is how am i going to pass the object to url  

"it should happen on click of the button, but this does not work even i change to below code.. It goes to the url but do not give me any data
$( "#MaintainRights").click( function() {

document.location.href = "/tile/mainRights.html"

I think that
@RequestMapping(value = "tile/list")
shoud be changed to
@RequestMapping(value = "/tile/mainRights")
then your link in JS should be changed to:
document.location.href = "/tile/mainRights";
