call the OData service.

about a product is provided? For example, the name of it? And which data types 
can be expected from these properties?<br />

 <p><strong><em>getEntitySet()</em></strong></p>
 <p>The procedure for declaring the <em>EntitySets</em> is similar.
 An <em>EntitySet</em> is a crucial resource, when an OData service is used to 
request data.
-In our example, we’ll invoke the following URL, which we expect to provide 
us a list of products:
-<code>html
-http://localhost:8080/DemoService/DemoServlet.svc/Products</code>
-When declaring an <em>EntitySet</em>, we need to define the type of entries 
which are contained in the list. Such type is an <em>EntityType</em>.
+In our example, we’ll invoke the following URL, which we expect to provide 
us a list of products:</p>
+<div class="codehilite"><pre><span class="n">http</span><span 
class="p">:</span><span class="o">//</span><span

class="p">.</span><span class="n">svc</span><span class="o">/</span><span 
class="n">Products</span>
+</pre></div>
+
+
+<p>When declaring an <em>EntitySet</em>, we need to define the type of entries 
which are contained in the list. Such type is an <em>EntityType</em>.
 In our example, we set our previously created <em>EntityType</em>, which is 
referred by a <em>FullQualifiedName</em>.</p>

 <p><strong>Summary:</strong><br />
 We have created a class that declares the metadata of our OData service.
 We have declared the main elements of an OData service: <em>EntityType</em>, 
<em>EntitySet</em>, <em>EntityContainer</em> and <em>Schema</em>.</p>
 <p>At runtime of an OData service, such metadata can be viewed by invoking the 
Metadata Document.</p>
-<p>In our example:
-<code>http://localhost:8080/DemoService/DemoService.svc/$metadata</code></p>
-<p><code>xml
-&lt;?xml version='1.0' encoding='UTF-8'?&gt;
-&lt;edmx:Edmx Version="4.0" 
xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx"&gt;
-  &lt;edmx:DataServices&gt;
-    &lt;Schema xmlns="http://docs.oasis-open.org/odata/ns/edm"; 
Namespace="com.example.model"&gt;
-      &lt;EntityType Name="Product"&gt;
-        &lt;Key&gt;
-          &lt;PropertyRef Name="ID"/&gt;
-        &lt;/Key&gt;
-        &lt;Property Name="ID" Type="Edm.Int32"/&gt;
-        &lt;Property Name="Name" Type="Edm.String"/&gt;
-        &lt;Property Name="Description" Type="Edm.String"/&gt;
-      &lt;/EntityType&gt;
-      &lt;EntityContainer Name="Container"&gt;
-        &lt;EntitySet Name="Products" 
EntityType="com.example.model.Product"/&gt;
-      &lt;/EntityContainer&gt;
-    &lt;/Schema&gt;
-  &lt;/edmx:DataServices&gt;
-&lt;/edmx:Edmx&gt;</code></p>
-<p>The Service Document can be invoked to view the Entity Sets, like in our 
example at
-<code>http://localhost:8080/DemoService/DemoService.svc/</code></p>
-<p><code>json
-{
-  "@odata.context" : 
"http://localhost:8080/DemoService/DemoService.svc/$metadata";,
-  "value" : [
-  {

 In our tutorial, to keep the code as simple as possible, we use a little

 Since we’re supposed to deliver the data inside an <em>EntitySet</em> 
instance, we create the instance, ask it for the (initially empty) list of 
entities and add some new entities to it.<br />

 <h3 id="432-edit-the-webxml">4.3.2. Edit the web.xml</h3>
 <p>The very last step of our tutorial is to register the Servlet in the 
<em>web.xml</em> file.<br />
 Furthermore, we need to specify the <em>url-pattern</em> for the servlet, such 
that our OData service can be invoked.</p>
 <p>Open the <em>src/main/webapp/WEB-INF/web.xml</em> file and paste the 
following content into it:</p>
-<p>```xml
