What happens after the user hits "Submit" on the Checkout Review Screen

This is more of a note taking page while I go through everything so it will be a little messy today.

The following URL is requested: <@ofbizUrl>processorder</@ofbizUrl>

1. request: "processorder" invokes CheckOutEvents.createOrder. If response = "success" continue...
2. request: "checkBlacklist" invokes CheckOutEvents.checkOrderBlacklist. If response = "success" continue..
3. request: "processpayment" invokes CheckOutEvents.processPayment

String processPayment(HttpServletRequest request, HttpServletResponse response)

This method calls:

private static boolean processPayment(HttpServletRequest request)

 public Map processPayment(GenericValue productStore, GenericValue userLogin, boolean faceToFace, boolean manualHold)

request: processorder, invoke: java event: CheckOutEvents: createOrder, responses = sales_order|work_order|error, values = checkBlacklist|checkBlackList|checkoutreview
