The next step is to retrieve the <code class="cCode">SOAPBodyElement</code> object. The method <code class="cCode">getChildElements</code> returns an <code class="cCode">Iterator</code> object that contains all of the child elements of the element on which it is called, so in the following lines of code, <code class="cCode">it1</code> contains the <code class="cCode">SOAPBodyElement</code> object <code class="cCode">bodyEl</code>, which represents the <code class="cCode">price-list</code> element.
</p>
<div class="pPreformattedRelative"><pre class="pPreformattedRelative">

The <code class="cCode">Iterator</code> object <code class="cCode">it2</code> holds the child elements of <code class="cCode">bodyEl</code>, which represent <code class="cCode">coffee</code> elements. Calling the method <code class="cCode">next</code> on <code class="cCode">it2</code> retrieves the first coffee element in <code class="cCode">bodyEl</code>. As long as <code class="cCode">it2</code> has another element, the method <code class="cCode">next</code> will return the next <code class="cCode">coffee</code> element.

The next lines of code drill down another level to retrieve the <code class="cCode">coffee-name</code> and <code class="cCode">price</code> elements contained in <code class="cCode">it3</code>. Then the message <code class="cCode">getValue</code> retrieves the text (a coffee name or a price) that the SAAJ coffee distributor added to the <code class="cCode">coffee-name</code> and <code class="cCode">price</code> elements when it gave content to <code class="cCode">response</code>. The final line in the following code fragment adds the coffee name or price to the <code class="cCode">Vector</code> object <code class="cCode">list</code>. Note that because of the nested while loops, for each <code class="cCode">coffee</code> element that the code retrieves, both of its child elements (the <code class="cCode">coffee-name </code>and <code class="cCode">price</code> elements) are retrieved.

<div class="pPreformattedRelative"><pre class="pPreformattedRelative">

The last code fragment adds the coffee names and their prices (as a <code class="cCode">PriceListItem</code>) to the <code class="cCode">ArrayList</code> <code class="cCode">priceItems</code>, and prints each pair on a separate line.

Ordering Coffee
</h4>
<a name="wp67778"> </a><p class="pBody">
The other kind of message that the Coffee Break server can send to the SAAJ distributor is an order for coffee. This is done in the <code class="cCode">placeOrder</code> method of <code class="cCode">OrderRequest</code>, which follows the DTD <code class="cCode">coffee-order.dtd</code>.

Creating the Order
</h5>
<a name="wp67893"> </a><p class="pBody">
As with the client code for requesting a price list, the <code class="cCode">placeOrder</code> method starts out by creating a <code class="cCode">SOAPConnection</code> object, creating a <code class="cCode">SOAPMessage</code> object, and accessing the message's <code class="cCode">SOAPEnvelope</code> and <code class="cCode">SOAPBody</code> objects.
</p>
<div class="pPreformattedRelative"><pre class="pPreformattedRelative">
SOAPConnectionFactory scf =
&nbsp;&nbsp;SOAPConnectionFactory.newInstance();

SOAPEnvelope envelope = part.getEnvelope();
SOAPBody body = envelope.getBody();<a name="wp67834"> </a>
</pre></div>
<a name="wp67900"> </a><p class="pBody">
Next the code creates and adds XML elements to form the order. As is required, the first element is a <code class="cCode">SOAPBodyElement</code>, which in this case is <code class="cCode">coffee-order</code>.

<div class="pPreformattedRelative"><pre class="pPreformattedRelative">

The application then adds the next level of elements, the first of these being <code class="cCode">orderID</code>.
