Obtaining a controller for working with resources
To modify, create, or delete portal resources using the Controller SPI, you first need to create a controller.You do this using a JNDI based lookup for the correct "home" interfaces that is, the corresponding read-only interface.
The provider lookup for a controller home is possible from servlet level code and portlets.
The following controllers are available via JNDI:
- ContentModelController
- To obtain a ContentModelController, perform a lookup for the string ContentModelControllerHome.CONTENT_MODEL_CONTROLLER_JNDI_NAME.
- PortletModelController
- To obtain a ContentModelController, perform a lookup for the string PortletModelControllerHome.PORTLET_MODEL_CONTROLLER_JNDI_NAME.
The LayoutModelController cannot be obtained via a JNDI lookup. You obtain it through its associated ContentModelController.
Example - Obtaining a content model controller:
ContentModelController result = null; final Context ctx = new InitialContext(); final ContentModelControllerHome home = (ContentModelControllerHome) ctx.lookup(ContentModelControllerHome.CONTENT_MODEL_CONTROLLER_JNDI_NAME); if (home != null) { result = home.getContentModelControllerProvider().createContentModelController(aContentModel); }To obtain a ContentModelController, you must pass an existing content model to the createContentModelController method of the ContentModelControllerProvider.
Example 2 - Obtaining a layout model controller for a specific page:
// locate the page for which to create a LayoutModelController final Locator locator = cmController.getLocator(); final ContentPage page = (ContentPage) locator.findByUniqueName("MyPage"); // create a LayoutModelController final LayoutModelController lmController = cmController.getLayoutModelController(page);
