Wie übergibt man die Werte in der Zeile möchte ich löschen/Bearbeiten, um die action-Klasse aus einer jsp in struts2 mit display-tag?

Möchte ich erstellen, Bearbeiten , löschen-link im display-tag mit struts2. Dies ist meine jsp-code

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@taglib uri="http://displaytag.sf.net" prefix="display" %>
<html>
<head>

    <title>Contact Manager - display tag Example</title>
    <link href="css/style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<display:table  name="contactList" requestURI="" pagesize="10" export="true" cellpadding="1" uid="sr"  cellspacing="1" size="50"
    defaultorder="ascending" sort="list" style="width:850"
     id="row">
            <display:column property="id" title="serial no" sortable="true"   />
            <display:column property="lastName" title="TV Show" sortable="true"   />

            <display:column property="emailId" title="Email Id" sortable="true"  />

            <display:column media="html"
    title="Delete"
    style="text-align:center">
    <s:url id="deleteUrl" action="deleteLink">
    <s:param name="id1" value="#attr.row.id" />
    </s:url>
    <s:a href="%{deleteUrl}">
         Delete
    </s:a>
</display:column>

<display:column media="html"
title="edit"
style="text-align:center">
<a href="deleteLink?id=<s:property value="id"/>">edit</a>
</display:column>

             <display:setProperty name="export.excel.filename" value="ActorDetails.xls"/>
            <display:setProperty name="export.pdf.filename" value="ActorDetails.pdf"/>
            <display:setProperty name="export.pdf" value="true" />
        </display:table>



</body>
</html>

dies ist meine Aktion Klasse:

    package net.viralpatel.contact.view;

    import java.util.List;

    import net.viralpatel.contact.controller.ContactManager;
    import net.viralpatel.contact.model.Contact;

    import com.opensymphony.xwork2.ActionSupport;


    public class ContactAction extends ActionSupport implements ModelDriven<Contact>,Preparable {

        private static final long serialVersionUID = 9149826260758390091L;

        private Contact contact;
        private List<Contact> contactList;


        private ContactManager linkController;

        public ContactAction() {
            linkController = new ContactManager();
        }



        public String getRecords()
        {
            contactList =linkController.lSist();

            return SUCCESS;
        } 

        public String deleteRecord()
        {
           System.out.println(contact.getId());

            return SUCCESS;
        } 

        public Contact getContact() {
            return contact;
        }

        public List<Contact> getContactList() {
            return contactList;
        }

        public void setContact(Contact contact) {
            this.contact = contact;
        }

        public void setContactList(List<Contact> contactsList) {
            this.contactList = contactsList;
        }


@Override
    public Contact getModel() {

        return contact;
    }

    @Override
    public void prepare() throws Exception {
        //TODO Auto-generated method stub
        contact = new Contact();
    }
    }

Wie bekomme ich die Werte der Attribute in der Zeile, die ich löschen von der jsp-Seite an den deleteRecord () - Methode in der ContactAction Klasse??
HIER wird die Aussage

System.out.println("ID IS "+contact.getId());

gibt einen ausgegeben: - ID IST null

Bitte schlagen einige Lösung.

Dank
