public class POStatusProcessor

extends AbstractProcessor

The POStatusProcessor runs business logic for the purchase order history portlet (purchaseorderhistory.portlet). This class handles the following portlet webflow events (See PortalAppflowConstants.PORTLET_WEBFLOW_EVENT_PARAMETER) directed to the price quote portlet:

1. submitPO
2. bea.portal.framework.internal.refresh
3. null

Events are acted upon by the process() method of this class.

In all cases where the process() method is invoked, purchase order XML files (see BuyerFactory.STATIC_PO_BASE_NAME, BuyerFactory.PO_FILE and BuyerFactory.PO_ACK_FILE) are parsed and the resulting List of PO objects are added to the RequestState.

The "submitPO" portlet webflow event indicates the intent of the user to submit a purchase order to a supplier. When this event is encountered the PurchaseQuote stored in the SessionState is submitted to the back-end workflow system. A value of Constants.MAXIMIZED is returned from the the process() method if the portlet is maximized, otherwise Constants.DISPLAY is returned.

The "bea.portal.framework.internal.refresh" and "null" events are handled identically. After adding the PO objects to the RequestState, a value of Constants.MAXIMIZED is returned from the the process() method if the portlet is maximized, otherwise Constants.DISPLAY is returned.

TIMEOUT_SECONDS

public static final long TIMEOUT_SECONDS

The default value for the purchase order timeout: 300 seconds.

TIMEOUT_PROP

public static final java.lang.String TIMEOUT_PROP

Override the default purchase order timeout (TIMEOUT_SECONDS) value by setting this system property, "samples.e2e.b2b.po.timeout", to some java long value greater than or equal to zero. The default value will be used if the property is set to an invalid value.

process

public java.lang.Object process(javax.servlet.http.HttpServletRequest request,
                                javax.servlet.http.HttpServletResponse response,
                                PortalRequest portalRequest,

                         throws ProcessingException

Processes events and runs business logic for the purchase order history 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.

Returns:

Constants.MAXIMIZED if the portlet is maximized, otherwise Constants.DISPLAY is returned.

Throws:

IllegalStateException - if no PurchaseQuote exists in the SessionState when processing a "submitPO" event.

E2EProcessingException - on a failure to submit the PurchaseQuote to the back-end workflow system.

Overrides:
