HELP! Exception when Programmatically Adding a Portlet to a Page

Question

We have been able to programmatically add WSRP Producers and Portlets into the BEA's local registry with WebLogic Portal 8.1 SP3. When we try to programmatically add a portlet to a page from within a JSP portlet we are hitting an issue. We are getting an exception when we try to call the addPlaceable method on the page instance manager. Here's the code snippet I'm using to programmatically add a portlet to a page:
IPageInstanceManager ipiManager = new PortalCustomizationManagerImpl();
CustomizationContext customizationContext = new CustomizationContext(ProxyPortletManager.LocaleHelper.findLocale("en"));
DesktopDefinitionId desktopDefinitionId = new DesktopDefinitionId("portal", new PortalPath("rdec"), new DesktopPath("enterprisePortal"));
PageInstanceId pageInstanceId = new PageInstanceId(6001);
PortletDefinitionId portletDefinitionId = new PortletDefinitionId(6002);
PlaceholderDefinitionId placeholderDefinitionId = new PlaceholderDefinitionId(2001);
PlaceableInstance placeableInstance = ipiManager.addPlaceable(customizationContext, desktopDefinitionId, pageInstanceId, portletDefinitionId, placeholderDefinitionId, 0);However, I get the following stack trace when the last line executes (ipiManager.addPlaceable):

Answer 1

sorry for all the replys (but i keep finding stuff)
PortalCustomizationManger is an EJB you can't just
instantiate a new instance
IPageInstanceManager ipiManager = new
PortalCustomizationManagerImpl();
you need to look it up
String JNDI_NAME =
ApplicationHelper.getApplicationName() +
".BEA_netuix.PortalPresentationManager";
portalCustomizationManagerHome =
(PortalCustomizationManagerHome)initialContext.lookup(
JNDI_NAME);
portalCustomizationManager =
portalCustomizationManagerHome.create();No need to apologize for all the replies, they are VERY MUCH appreciated. Thank you.
I tried your suggestion (although I had to change the JNDI lookup to lookup the PortalCustomizationManager instead of the PortalPresentationManager because of a ClassCastException) and I get a NullPointerException. Here is the code I am using:
InitialContext initialContext = new InitialContext();
CustomizationContext customizationContext = new CustomizationContext(ProxyPortletManager.LocaleHelper.findLocale("en"), request);
DesktopDefinitionId desktopDefinitionId = new DesktopDefinitionId("portal", new PortalPath("rdec"), new DesktopPath("enterprisePortal"));
PageInstanceId pageInstanceId = new PageInstanceId(6001);
PortletDefinitionId portletDefinitionId = new PortletDefinitionId(6002);
PlaceholderDefinitionId placeholderDefinitionId = new PlaceholderDefinitionId(2001);
PortalCustomizationManagerHome pageDefinitionManagerHome = (PortalCustomizationManagerHome) initialContext.lookup("RDECPortal.BEA_netuix.PortalCustomizationManager");
PortalCustomizationManager pageDefinitionManager = pageDefinitionManagerHome.create();
PlaceableInstance placeableInstance = pageDefinitionManager.addPlaceable(customizationContext, desktopDefinitionId, pageInstanceId, portletDefinitionId, placeholderDefinitionId, 0);...and here is the full stack trace I get when the code is executed:
