public class ProductInventory

extends AbstractProcessor

The ProductInventory processor runs business logic for the product inventory portlet (productinventory.portlet).

This class handles the following portlet webflow events (See PortalAppflowConstants.PORTLET_WEBFLOW_EVENT_PARAMETER) directed to the product inventory portlet:

1. selectProduct
2. reset
3. bea.portal.framework.internal.refresh
4. null

All paths through the process() method first call the InventoryProvider EJB to obtain a List of products and stores the List in the RequestState object for the current request.

The "selectProduct" portlet webflow event indicates that the user has selected a particular product from the list displayed in the portlet. The Helper.getProductParameter(javax.servlet.http.HttpServletRequest) method is used to obtain the product id from the HttpServletRequest. The product id is compared against the List of products obtained via the InventoryProvider EJB, and the matching Inventory object is stored in the user's SessionState. Following the successful completion of the aforementioned work the StateValue of the SessionState is set to StateValue.PRODUCT_SELECTED and a value of Constants.DISPLAY is returned to the caller.

The "reset" portlet webflow event is used to restart the purchasing process, typically after a purchase order has been submitted and an acknowledgement has been received from the corresponding supplier. When this event is encountered by the process() method the StateValue of the SessionState is set to StateValue.START, XML and data files are deleted and a value of Constants.DISPLAY is returned to the caller.

The "bea.portal.framework.internal.refresh" and "null" portlet webflow events simply return Constants.DISPLAY after obtaining the List of products from the InventoryProvider EJB.

                         throws ProcessingException

Processes webflow events directed to the product inventory portlet (productinventory.portlet).

Parameters:

request - an HttpServletRequest to process.

response - the HttpServletRequest associated with the request.

portalRequest - the PortalRequest associated with this http request.

requestContext - the webflow request context.

session - the PipelineSession object associated with this request.

requestState - the RequestState associated with this http request.

sessionState - the SessionState associated with this user session.

Throws:

IllegalStateException - if the product id supplied for a "selectProduct" event is not found in the List of products retrieved from the InventoryProvider EJB.

E2EProcessingException - if unable to create or call the InventoryProvider EJB.

Overrides:
