Portlet WindowURL to render a portlet that is in different page

[Gopikrishna Gopal]

I am having a portlet `PortletA` in Page1 and PortletB in Page2

On submitting the form in `PortletA`, I am trying to invoke/render `PortletB` using `WindowURL`. But I am not successful and remain in `PorltetA` itself.
This is how I am doing...

PortletA
========

 <%@ page language="java" contentType="text/html;charset=UTF-8" import="com.bea.portlet.WindowURL" %>

    <%
    WindowURL url = WindowURL.createWindowURL(request, response, "/PortletB");
    System.out.println("url:" + url.toString());
    %>
    
    <form id="id1" action ="<%= url.toString() %>" >
        <input type="submit" value="Click">
    </form>

url value that is getting printed is -

http://localhost:7001/Demo/actionPortal.portal?_nfpb=true&_st=&_windowLabel=%2FPortletB&_pageLabel=Page1

I also tried `<portlet:renderURL>`,

    <portlet:renderURL var="maxhelp" windowLabel="PortletB" />

But still same.

Please let me know if anything wrong.
