Creating the Order

As with the client code for requesting a price list, the placeOrder method starts by creating a SOAPConnection object and a SOAPMessage object and accessing the message’s SOAPBody object.

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
SOAPConnection con = scf.createConnection();

MessageFactory mf = MessageFactory.newInstance();
SOAPMessage msg = mf.createMessage();

SOAPBody body = msg.getSOAPBody();

Next, the code creates and adds XML elements to form the order. As is required, the first element is a SOAPBodyElement, which in this case is coffee-order.

QName bodyName = new QName("http://sonata.coffeebreak.com",
    "coffee-order", "PO");
SOAPBodyElement order = body.addBodyElement(bodyName);

The application then adds the next level of elements, the first of these being orderID. The value given to orderID is extracted from the OrderBean object passed to the OrderRequest.placeOrder method.

QName orderIDName = new QName("orderID");
SOAPElement orderID = order.addChildElement(orderIDName);
orderID.addTextNode(orderBean.getId());

The next element, customer, has several child elements that give information about the customer. This information is also extracted from the Customer component of OrderBean.

QName childName = new QName("customer");
SOAPElement customer = order.addChildElement(childName);

childName = new QName("last-name");
SOAPElement lastName = customer.addChildElement(childName);
lastName.addTextNode(orderBean.getCustomer().getLastName());

childName = new QName("first-name");
SOAPElement firstName = customer.addChildElement(childName);
firstName.addTextNode(orderBean.getCustomer().getFirstName());

childName = new QName("phone-number");
SOAPElement phoneNumber = customer.addChildElement(childName);
phoneNumber.addTextNode(orderBean.getCustomer().getPhoneNumber());

childName = new QName("email-address");
SOAPElement emailAddress = customer.addChildElement(childName);
emailAddress.addTextNode(orderBean.getCustomer().getEmailAddress());

The address element, added next, has child elements for the street, city, state, and zip code. This information is extracted from the Address component of OrderBean.

childName = new QName("address");
SOAPElement address = order.addChildElement(childName);

childName = new QName("street");
SOAPElement street = address.addChildElement(childName);
street.addTextNode(orderBean.getAddress().getStreet());

childName = new QName("city");
SOAPElement city = address.addChildElement(childName);
city.addTextNode(orderBean.getAddress().getCity());

childName = new QName("state");
SOAPElement state = address.addChildElement(childName);
state.addTextNode(orderBean.getAddress().getState());

childName = new QName("zip");
SOAPElement zip = address.addChildElement(childName);
zip.addTextNode(orderBean.getAddress().getZip());

The element line-item has three child elements: coffeeName, pounds, and price. This information is extracted from the LineItems list contained in OrderBean.

List<LineItemBean> lineItems = orderBean.getLineItems();
Iterator<LineItemBean> i = lineItems.iterator();
while (i.hasNext()) {
    LineItemBean lib = i.next();

    childName = new QName("line-item");
    SOAPElement lineItem = order.addChildElement(childName);

    childName = new QName("coffeeName");
    SOAPElement coffeeName = lineItem.addChildElement(childName);
    coffeeName.addTextNode(lib.getCoffeeName());

    childName = new QName("pounds");
    SOAPElement pounds = lineItem.addChildElement(childName);
    pounds.addTextNode(lib.getPounds().toString());

    childName = new QName("price");
    SOAPElement price = lineItem.addChildElement(childName);
    price.addTextNode(lib.getPrice().toString());
}

// total
childName = new QName("total");
SOAPElement total = order.addChildElement(childName);
total.addTextNode(orderBean.getTotal().toString());

With the order complete, the application sends the message to the endpoint http://localhost:8080/saaj-coffee-supplier/orderCoffee and closes the connection.

URL endpoint = new URL(url);
SOAPMessage reply = con.call(msg, endpoint);
con.close();

Because the given endpoint is mapped to ConfirmationServlet, the Application Server executes that servlet (discussed in Returning the Order Confirmation) to create and return the SOAPMessage object reply.
