HI,
I have encountered one example of display tag on some website.I implemented the same but still it is not working properly.

1)I have following class ActorData having tvShow,userName,emailId as variables

package actor;

import java.util.ArrayList;

public class ActorData {

private String tvShow;
    private String userName;
    private String emailId;

public ActorData() {
    }

public ActorData(String tvShow, String userName, String emailId) {
        this.tvShow = tvShow;
        this.userName = userName;
        this.emailId = emailId;
    }

public ArrayList loadData() {
        ArrayList userList = new ArrayList();
        userList.add(new ActorData("The Office", "Michael Scott",
                "michael.scott@dundermifflin.com"));
        userList.add(new ActorData("The Office", "Dwight Schrute",
                "dwight.schrute@dundermifflin.com"));
        userList.add(new ActorData("The Office", "Jim Halpert",
                "jim.halpert@dundermifflin.com"));
        userList.add(new ActorData("The Office", "Pam Beesly",
                "pam.beesly@dundermifflin.com"));
        userList.add(new ActorData("The Office", "Andy Bernad",
                "andy.bernad@dundermifflin.com"));
        userList.add(new ActorData("The Office", "Angela Martin",
                "angela.martin@dundermifflin.com"));
        userList.add(new ActorData("Friends", "Rachel Green",
                "rachel.green@friends.com"));
        userList.add(new ActorData("Friends", "Monica Geller",
                "monica.geller@friends.com"));
        userList.add(new ActorData("Friends", "Phoebe Buffay",
                "phoebe.buffay@friends.com"));
        userList.add(new ActorData("Friends", "Joey Tribbiani",
                "joey.tribbiani@friends.com"));
        userList.add(new ActorData("Friends", "Chandler Bing",
                "chandler.bing@friends.com"));
        userList.add(new ActorData("Friends", "Ross Geller",
                "ross.geller@friends.com"));
        return userList;
    }

public String getTvShow() {
        return tvShow;
    }

public String getUserName() {
        return userName;
    }

public String getEmailId() {
        return emailId;
    }
}

2)FormBean Class-UserForm

3)Action Class-UserAction

4)First Page-actor.jsp

5)Targeted Page-actorDetails.jsp

<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
<%
        UserForm uf = (UserForm) session.getAttribute("UserForm");
        ArrayList l = uf.getActorList();

Iterator i = l.iterator();
        while (i.hasNext()) {
            ActorData a = (ActorData) i.next();
            out.println(a.getUserName());
            out.println(a.getTvShow());
            out.println(a.getEmailId());

%>
<br>
<%
        }

%>
<display:table id="data" name="actor.UserForm.actorList" requestURI="/userAction.do" pagesize="10" >
<display:column property="tvShow" title="TV Show" sortable="true" media="html" group="1" />
<display:column property="userName" title="User Name" sortable="true"/>
<display:column property="emailId" title="Email Id" sortable="true"/>
</display:table>

6)Struts-config.xml

Here request is successfully redirected from acotr.jsp to actorDetails.jsp.
On actorDetails.jsp it is printing all acotor data but for display tag is showing nothing to display

What could be wrong in above case?

Here is link that I referred.

Thanks in advance,
