The
DynamicUICtrl
, has a addPortlet()
methdo that you can use for adding portlet to page on the fly so i built this sample portlet to add com.webspherenotes.popup.portlet
on the fly but it does not work
package com.webspherenotes.portlet;

ObjectID dynamicPortletObjectId = dynamicUIControl.addPortlet(templatePortletObjectId, new LocalizedImpl("Dynamic page", "Dynamic page demo"), null);
System.out.println("Lauch portlet object id " + dynamicPortletObjectId);
if(dynamicPortletObjectId == null)
return;
EngineURL dynamicPageURL = redirectURLGenerator.createPortletURL(dynamicPortletObjectId);
String dynamicPageURLStr = dynamicPageURL.toString();
System.out.println("Dynamic Page URL " + dynamicPageURLStr);
response.sendRedirect(dynamicPageURLStr);
} catch (DynamicUIManagementException e) {

.lookup("portletservice/com.ibm.portal.portlet.service.dynamicui.DynamicUIManagementFactoryService");
dynamicUIManagerFactoryService = (DynamicUIManagementFactoryService) dynamicUIManagerFactoryServiceHome
.getPortletService(DynamicUIManagementFactoryService.class);

private ObjectID getObjectID(String uniqueNameStr) {
try {

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;
}
}
The
dynamicUIControl.addPortlet(templatePortletObjectId, new LocalizedImpl("Dynamic page", "Dynamic page demo"), null)
method always returns null, i tried quite few combination but they do not help, i saw few question on ibm developerworks forum where other developers are also facing some problem but it seems that we will have to open a PMR with IBM and see how it goes
