Struts 2 Framework - Redirect to Action

Good day!

I am currently studying Struts 2 and I am quite confused with the xml. I don't know where to start.

I want my index.jsp to go to my Display Action Class So My codes is as follows:

index.jsp 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
   <META HTTP-EQUIV="Refresh" CONTENT="0;URL=package.action/DisplayContactAction">
</head>
<body>
</body>
</html>

struts.xml

   <action name="index">
        <result type="redirectAction">
            <param name="actionName">HelloWorld</param>
            <param name="namespace">/example</param>
        </result>
    </action>

Can anyone explain to me what the code on the struts.xml above means.

After I redirect my page to the action class, i want it to go to the display.jsp

Action Class

    private ArrayList<Contacts> contactsList;
    private int id;
    private String firstName;
    private String lastName;
    private String telNumber;
    private String email;

    public String execute() {
        String result = null;

        ContactsManager contactsManager = ContactsManager.getInstance();
        contactsList = ContactsManager.getContactsList();

        result = "success";
        return result;
     }

Now... How can I pass the value using xml? Also, how can i transfer the data generated on my action class to the jsp?

Thank you.

The following result would redirect to the URL for the HelloWorld action (likely /example/HelloWorld).

<result type="redirectAction">
    <param name="actionName">HelloWorld</param>
    <param name="namespace">/example</param>
</result>

It calls the getUriFromActionMapping(ActionMapping) method of the ActionMapper to determine the URL to redirect to. You could also use a standard redirect type (type="redirect").

Also, how can i transfer the data generated on my action class to the jsp?

You'll need a getter to expose the data and then you can access it in the JSP.
