I followed the instructions in Exploiting the WebSphere Portal 5.1.0.1 programming model: Part 4: Making your portal dynamic and context sensitive article to create a sample portlet that will create a dynamic page and then display that page in dialog box. THis is how my sample portlet looks like
package com.webspherenotes.portlet;
import java.io.IOException;
import javax.naming.CompositeName;
import javax.naming.InitialContext;
import javax.naming.InvalidNameException;

public class DynamicUIPortlet extends GenericPortlet {
public static final String EXTENSION_PAGE_UNIQUENAME="com.webspherenotes.popup.extension";
public static final String TEMPLATE_PAGE_UNIQUENAME="com.webspherenotes.popup.dynamic";
public void processAction(ActionRequest request, ActionResponse response)
throws PortletException, IOException {
System.out.println("Entering DynamicUIPortlet.processAction()");
try {
RedirectURLGenerator redirectURLGenerator = redirectURLGeneratorService.getURLGenerator(request, response);
DynamicUICtrl dynamicUIControl= dynamicUIManagerFactoryService.getDynamicUICtrl(request, response, EXTENSION_PAGE_UNIQUENAME);
ObjectID templatePageObjectId = getObjectID(TEMPLATE_PAGE_UNIQUENAME);
System.out.println("Template Page Object Id " + templatePageObjectId);
ObjectID dynamicPageObjectId = dynamicUIControl.addPage(templatePageObjectId, new LocalizedImpl("Dynamic page", "Dynamic page demo"), null);
System.out.println("Lauch page object id " + dynamicPageObjectId);
EngineURL dynamicPageURL = redirectURLGenerator.createPageURL(dynamicPageObjectId);
String dynamicPageURLStr = dynamicPageURL.toString();
System.out.println("Dynamic Page URL " + dynamicPageURLStr);
response.sendRedirect(dynamicPageURLStr);
} catch (DynamicUIManagementException e) {
e.printStackTrace(System.out);
} catch (StateException e) {
e.printStackTrace(System.out);
}
System.out.println("Exiting DynamicUIPortlet.processAction()");
}
protected void doView(RenderRequest request, RenderResponse response)
throws PortletException, IOException {
System.out.println("Entering DynamicUIPortlet.doView()");
getPortletContext().getRequestDispatcher("/index.jsp").include(request, response);
System.out.println("Exiting DynamicUIPortlet.doView()");
}
RedirectURLGeneratorFactoryService redirectURLGeneratorService;
DynamicUIManagementFactoryService dynamicUIManagerFactoryService;
public void init() throws PortletException {
System.out.println("ENtering DynamicUIPortlet.init()");
try {
InitialContext ctx = new InitialContext();
final PortletServiceHome dynamicUIManagerFactoryServiceHome = (PortletServiceHome) ctx
.lookup("portletservice/com.ibm.portal.portlet.service.dynamicui.DynamicUIManagementFactoryService");
dynamicUIManagerFactoryService = (DynamicUIManagementFactoryService) dynamicUIManagerFactoryServiceHome
.getPortletService(DynamicUIManagementFactoryService.class);
final PortletServiceHome redirectServiceHome = (PortletServiceHome) ctx
.lookup("portletservice/com.ibm.portal.portlet.service.state.RedirectURLGeneratorFactoryService");
redirectURLGeneratorService = (RedirectURLGeneratorFactoryService) redirectServiceHome
.getPortletService(RedirectURLGeneratorFactoryService.class);
} catch (NamingException e) {
e.printStackTrace(System.out);
}
System.out.println("Exiting DynamicUIPortlet.init()");
}
private ObjectID getObjectID(String uniqueNameStr) {
try {
InitialContext ctx = new InitialContext();
final Name uniqueName = new CompositeName("portal:uniquename");
uniqueName.add(uniqueNameStr);
ObjectID oidForUniqueName = (ObjectID) ctx.lookup(uniqueName);
return oidForUniqueName;
} catch (InvalidNameException e) {
e.printStackTrace(System.out);
} catch (NamingException e) {
e.printStackTrace(System.out);
}
return null;
}
}
In the doView() method of the DynamicUIPortlet, i am forwarding control to index.jsp page, which looks like this
<%@page language="java" contentType="text/html; %>
<%@taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="/WEB-INF/tld/portal.tld" prefix="portal" %>
<portlet:defineObjects />
<script type="text/javascript">
<!--
function openPopup(popupUrl){
if (window.showModalDialog) {
window.showModalDialog(popupUrl,"name","dialogWidth:455px;dialogHeight:450px");
} else {
window.open(popupUrl,'name',
'height=500,width=500,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,
resizable=no ,modal=yes');
}
}
//-->
</script>
<input type="button" onclick="openPopup('<portlet:actionURL/>')" value="Dynamic Page" />
<br/>
When you click on the DYnamic Page button it creates a actionURL and opens it in the dialog box.
The DynamicUIService has restriction that you can call it only during the action phase of the portlet, so inside the processAction() method i am calling
dynamicUIControl.addPage()
method to add a dynamic page and then create redirectURL to the newly created page by calling redirectURLGenerator.createPageURL()
method and then redirecting it to that URL. This is the UI that i get when i click on the Dynamic Page button
