Facing an issue with checkout api

[Sagar11221]

I am not able to place order when using this checkout api (" http://localhost:8080/api/v1/cart/{code}/checkout").

In order to solve this issue, the modifications in certain .java classes have to be done-

1-OrderApi.java
This class consist of a checkout method which is actually being executed by Checkout Api .In this you have to comment the "if condition" that is checking " //check if customer already exist" for every new registered use because of which it is throwing "ServiceRuntimeException"

2-OrderFacadeImpl.java
In this also you have to comment the same "if condition" line that is after "//lookup existing customer" and also comment try and catch block that is coming after "// update cart" and "//email management" line.

3 OrderService.java
In this you have to add some @params above the "processOrder()" method to where there is no transaction parameter in the method, inorder to make "processOrder()" method work.

        /**
             * Placing orders. Mainly used in the administration tool
             * @param order
             * @param customer
             * @param items
             * @param summary
             * @param payment
             * @param store
             * @return
             * @throws ServiceException
             */

4 OrderServiceImpl.java

Comment the lines

      "// first process payment
              // Transaction processTransaction = paymentService.processPayment(customer,
              // store, payment, items, order);"

Write this code after the "if condition" that is after the above commented line

     Set<OrderStatusHistory> statusHistorySet = new HashSet<OrderStatusHistory>();
     OrderStatusHistory statusHistory = new OrderStatusHistory();
     statusHistory.setStatus(order.getStatus());
     statusHistory.setDateAdded(order.getDatePurchased());
     System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&&&&aftersetdateadded&&");
     statusHistory.setOrder(order);
     statusHistorySet.add(statusHistory);
     order.setOrderHistory(statusHistorySet);

If not adding this above code will get the "not-null property exception" for "dateAdded" property in OrderStatusHistory.java class because eventually the dateAdded property is not getting set after if condition.

    // if(transaction!=null) {
    // transaction.setOrder(order);
    // if(transaction.getId()==null || transaction.getId()==0) {
    // transactionService.create(transaction);
    // } else {
    // transactionService.update(transaction);
    // }
    // }

    // if(processTransaction!=null) {
    // processTransaction.setOrder(order);
    // if(processTransaction.getId()==null || processTransaction.getId()==0) {
    // transactionService.create(processTransaction);
    // } else {
    // transactionService.update(processTransaction);
    // }
    // }

    /**
     * decrement inventory
     */
    // LOGGER.debug("Update inventory");
    // Set<OrderProduct> products = order.getOrderProducts();
    // for (OrderProduct orderProduct : products) {
    //     orderProduct.getProductQuantity();
    //     Product p = productService.getById(orderProduct.getId());
    //     if (p == null)
    //         throw new ServiceException(ServiceException.EXCEPTION_INVENTORY_MISMATCH);
    //     for (ProductAvailability availability : p.getAvailabilities()) {
    //         int qty = availability.getProductQuantity();
    //         if (qty < orderProduct.getProductQuantity()) {
    //             // throw new ServiceException(ServiceException.EXCEPTION_INVENTORY_MISMATCH);
    //             LOGGER.error("APP-BACKEND [" + ServiceException.EXCEPTION_INVENTORY_MISMATCH + "]");
    //         }
    //         qty = qty - orderProduct.getProductQuantity();
    //         availability.setProductQuantity(qty);
    //     }
    //     productService.update(p);
    // }

And you can test the checkoutapi now, it will work fine
