I downloaded the JBoss Portal source and had a thorough look at the admin portlets (core-admin project), in which the portal structure is modified. Then, I imitated it in my own portlet. Here is how it works: Entries in jboss-portlet.xml to get access to some JBoss-Services: | <service> | <service-name>PortalObjectContainer</service-name> | <service-class>org.jboss.portal.core.model.portal.PortalObjectContainer</service-class> | <service-ref>:container=PortalObject</service-ref> | </service> | <service> | <service-name>InstanceContainer</service-name> | <service-class>org.jboss.portal.core.model.instance.InstanceContainer</service-class> | <service-ref>:container=Instance</service-ref> | </service> | <service> | <service-name>AuthorizationDomainRegistry</service-name> | <service-class>org.jboss.portal.security.AuthorizationDomainRegistry</service-class> | <service-ref>:service=AuthorizationDomainRegistry</service-ref> | </service> | <service> | <service-name>FederatingPortletInvoker</service-name> | <service-class>org.jboss.portal.portlet.federation.FederatingPortletInvoker</service-class> | <service-ref>:service=PortletInvoker,type=Federating</service-ref> | </service> | Java-Code example in the portlet, including iteration through all deployed portlets, creating a portal page, creating a portlet instance and putting in in a window on that page: PortalObjectContainer container = (PortalObjectContainer) getPortletContext().getAttribute("PortalObjectContainer"); | InstanceContainer instanceContainer = (InstanceContainer) getPortletContext().getAttribute("InstanceContainer"); | FederatingPortletInvoker portletInvoker = (FederatingPortletInvoker) getPortletContext().getAttribute("FederatingPortletInvoker"); | AuthorizationDomainRegistry registry = (AuthorizationDomainRegistry) getPortletContext().getAttribute("AuthorizationDomainRegistry"); | | try { | // create a portal page | Page page = container.getContext().getDefaultPortal().createPage("MyPage" + counter); | | // iterate through existing portlets and select one | List<Portlet> tmpPortlets = new ArrayList(portletInvoker.getFederatedInvoker("local").getPortlets()); | for (Portlet portlet : tmpPortlets) { | if(portlet.getInfo().getName().equals("WeatherPortlet")){ | // create an instance of the selected portlet | InstanceDefinition def = instanceContainer.createDefinition("MyPortlet" + counter, portlet.getContext().getId()); | // configuring security | DomainConfigurator configurator = registry.getDomain("instance").getConfigurator(); | Set constraints = Collections.singleton(new RoleSecurityBinding("view", SecurityConstants.UNCHECKED_ROLE_NAME)); | configurator.setSecurityBindings(def.getId(), constraints); | // create a window containing the portlet | Window window = page.createWindow("MyWindow" + counter, ContentType.PORTLET, def.getId()); | window.setDeclaredProperty(ThemeConstants.PORTAL_PROP_REGION, "right"); | window.setDeclaredProperty(ThemeConstants.PORTAL_PROP_ORDER, "" + Integer.MAX_VALUE); | } | } | | } catch (IllegalArgumentException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (DuplicatePortalObjectException e) { | // TODO Auto-generated catch block | e.printStackTrace(); | } catch (DuplicateInstanceException e1) { | // TODO Auto-generated catch block | e1.printStackTrace(); | } catch (PortletInvokerException e1) { | // TODO Auto-generated catch block | e1.printStackTrace(); | } View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240212#...
