-                JDO provides persistence of objects. The logical next step after persisting

-                objects is to retrieve them for use in your application. 
-                There are several ways to do this
-            </p>

-            <div class="section"><h3>Retrieve an object from its identity<a
name="Retrieve_an_object_from_its_identity"></a></h3>
-                <p>
-                    The simplest form of object retrieval is where we have the identity.

-                    This is simply 
-                </p>
-                <div class="source"><pre>
-Object obj = pm.getObjectById(identity);
-                </pre></div>
-                <p>
-                    If the object is in the JDO cache then it is retrieved from there, 
-                    otherwise the JDO implementation goes to the datastore. When the object

-                    is retrieved its fields are populated according to its Fetch Group.
-                </p>
-            </div>
-
-            <div class="section"><h3>Retrieve an object based on its Extent<a
name="Retrieve_an_object_based_on_its_Extent"></a></h3>
-                <p>
-                    A persistable class can be persisted with an <b>Extent</b>
of all 
-                    instances of that type.
-                    You can use this to retrieve objects of the required type, like this
-                </p>
-                <div class="source"><pre>
-Extent ex = pm.getExtent(MyClass.class, true);
-Iterator iter = ex.iterator();
-while (iter.hasNext())
-{
-    MyClass obj = (MyClass)iter.next();
-    ...
-}</pre></div>
-                <p>
-                    The second argument in the <i>getExtent</i> call is whether
to include 
-                    instances of subclasses.

-                <p>
-                    Where we want to retrieve all objects based on some criteria (e.g all

-                    objects of class A where field 'x' of A is a certain value) we need to

-                    use a query language. JDO2 provides 2 options here. JDOQL is object-based

-                    and allows you to express your query in terms of the classes and fields
-                    you are using. SQL is datastore-based and allows you to express your
query 
-                    in terms of the datastore tables and columns.
-                </p>
-                <p>

+                JDO provides persistence of objects. The logical next step after persisting

+                objects is to retrieve them for use in your application. 
+                There are several ways to do this
+            </p>

+            <div class="section"><h3>Retrieve an object from its identity<a
name="Retrieve_an_object_from_its_identity"></a></h3>
+                <p>
+                    The simplest form of object retrieval is where we have the identity.

+                    This is simply 
+                </p>
+                <div class="source"><pre>
+Object obj = pm.getObjectById(identity);

+                <p>
+                    If the object is in the JDO cache then it is retrieved from there, 
+                    otherwise the JDO implementation goes to the datastore. When the object

+                    A persistable class can be persisted with an <b>Extent</b>
of all 
+                    instances of that type.
+                    You can use this to retrieve objects of the required type, like this
+                </p>
+                <div class="source"><pre>

+                <p>
+                    The second argument in the <i>getExtent</i> call is whether
to include

+                    use a query language. JDO2 provides 2 options here. JDOQL is object-based

+                    and allows you to express your query in terms of the classes and fields
+                    you are using. SQL is datastore-based and allows you to express your
query 
+                    in terms of the datastore tables and columns.
+                </p>
+                <p>

-                    The <i>makePersistent</i> method of <b>PersistenceManager</b>
makes the object persistent in 
-                    the datastore, and updates the 'state' of the object from <i>Transient</i>
(at the start) 
-                    to <i>Hollow</i> (after commit() of the transaction).

-                    When an object is persisted, if it has any other objects referenced from
that object they 
-                    also will be made persistent. This is referred to as <b>persistence-by-reachability</b>.

-                    The main benefit of this is that if you have an object graph to persist,
then you don't 
-                    need to call <i>makePersistent()</i> on all objects, instead
just using one that can be 
-                    used to find all of the others. <b>persistence-by-reachability</b>
is also run at the time of
-                    calling <i>commit()</i> on the transaction. This has the
effect that if you had called 
-                    <i>makePersistent()</i> on an object and that had persisted
another object, and before 
-                    commit you had removed the relation to this other object, then at <i>commit()</i>
the 
-                    reachability algorithm will find that this other object is no longer
reachable and will 
-                    remove it from persistence.

+            <p>
+                Any JDO-enabled application will require at least one <i>PersistenceManager</i>
(PM).
+                This is obtained from the <a href="pmf.html">PersistenceManagerFactory</a>
for the datastore.

+            <p>
+                The simplest way of creating a <i>PersistenceManager</i>

+                A <i>PersistenceManager</i> is the key to all persistence operations
in JDO. With it you can
+                persist, update, delete, and retrieve objects from the datastore. A <i>PersistenceManager</i>
+                has a single transaction.

+                <p>
+                    To persist an object, the object must first be marked as persistable
using
+                    <a href="metadata.html">MetaData (XML/Annotations)</a>. Then
you would start the
+                    PM transaction, and use <i>makePersistent</i> as follows

+                <p>
+                    The <i>makePersistent</i> method of <b>PersistenceManager</b>
makes the object persistent in 
+                    the datastore, and updates the 'state' of the object from <i>Transient</i>
(at the start) 
+                    to <i>Hollow</i> (after commit() of the transaction).
+                </p>
+                <p>
+                    When an object is persisted, if it has any other objects referenced from
that object they 
+                    also will be made persistent. This is referred to as <b>persistence-by-reachability</b>.

+                    The main benefit of this is that if you have an object graph to persist,
then you don't 
+                    need to call <i>makePersistent()</i> on all objects, instead
just using one that can be 
+                    used to find all of the others. <b>persistence-by-reachability</b>
is also run at the time of
+                    calling <i>commit()</i> on the transaction. This has the
effect that if you had called 
+                    <i>makePersistent()</i> on an object and that had persisted
another object, and before 
+                    commit you had removed the relation to this other object, then at <i>commit()</i>
the 
+                    reachability algorithm will find that this other object is no longer
reachable and will 
+                    remove it from persistence.
