+<h1>Object Content Manager</h1>
<p>The main component in the OCM framework is the ObjectContentManager. It converts an object graph into JCR nodes and properties and vice versa. The ObjectContentManager is always associated with a JCR Session. It is used to retrieve, create, update and delete objects from a JCR content repository. Usually there is one ObjectContentManager per user session.</p>

+<h2><a name="How_does_the_Object_Content_Manager_work_.3F"></a>How does the Object Content Manager work ?</h2>
<p>Thanks to a Mapping Descriptor, the ObjectContentManager is able to use the appropriate mapping strategy for each persistent object (pojo). The Mapping Descriptor contains one Class Descriptor per persistent class. Each Class Descriptor contains mapping information for the corresponding class attributes.</p>
<p>In the point of view implementation, the Mapping Descriptor is a java object injected into the ObjectContentManager (see the interface org.apache.jackrabbit.ocm.mapper.Mapper). Right now, there are 2 different Mapping Descriptor implementations:</p>
-
<ul>
-
+
<li>Annotation : each persistent object is annoted in order to provide to the ObjectContentManager all the required information on its mapping strategy (see the class org.apache.jackrabbit.ocm.mapper.impl.annotation.AnnotationMapperImpl).</li>
-
<li>XML configuration file : the class descriptors are defined in one or more XML config files used by the ObjectContentManager when it is instantiated (see the class org.apache.jackrabbit.ocm.mapper.impl.digester.DigesterMapperImpl).</li>
</ul>
-<p>For a business developer, it is not necessary to know how the ObjectContentManager is using the Class Descriptors. He has to make only a choice between annotated classes or XML files. Below, you can see how to setup correctly an ObjectContentManager. </p></div>

<p>In all cases, a persistent object (a pojo) is mapped into a JCR node and its fields are mapped into subnodes or properties depending on their types.</p>
<p>There are 3 “field types”:</p>
-
<ul>
-
+
<li>
-<p>Atomic fields<br />Primitive data types and simple objects (String, Long, Double, …) . Those fields are mapped into JCR properties.</p></li>
