To make my topic more clear, we can assume a concrete Portlet Page. To this Page it is possible to assign Portlet Instances, which should be displayed on the page. Many portlet Instances could reference to one Portlet Reference. This relationship is stored in the portals database. During the Portals Startup these information have to be stored in objects. I need to get access to these objects, which hold the information about Portlet Page assigned Portlet Instances and which portlet definition is referenced. My hope is, that I get access by using some MBeans for this purpose. I already find MBeans like: service=PortletInvoker,type=Container in the Portal domain. This MBeans hold the Portlets, but now I need a Mbean which give me a List of Windows and Portlet Instances registered in the Portal.
