| OpenJPA deployment includes choosing a factory deployment strategy, and in a |
| managed environment, optionally integrating with your application server's |
| managed and XA transactions. This chapter examines each aspect of deployment in |
| turn. |

| <p> |
| The JPA Overview describes the <code class="classname">javax.persistence.Persistence |
| </code> class. You can use <code class="classname">Persistence</code> to obtain |
| <code class="classname">EntityManagerFactory</code> instances, as demonstrated in |
| <a class="xref" href="jpa_overview_persistence.html" title="Chapter 6. Persistence">Chapter 6, <i> |
| Persistence |
| </i></a>. OpenJPA also extends |
| <code class="classname">Persistence</code> to add additional <code class="classname"> |
| EntityManagerFactory</code> creation methods. The <code class="classname"> |
| org.apache.openjpa.persistence.OpenJPAPersistence</code> class |
| <a class="ulink" href="../javadoc/org/apache/openjpa/persistence/OpenJPAPersistence.html" target="_top"> |
| Javadoc</a> details these extensions. |
| </p> |
| <p> |
| After obtaining the factory, you can cache it for all <code class="classname"> |
| EntityManager</code> creation duties. OpenJPA factories support being |
| bound to JNDI as well. |

| <p> |
| Java EE application servers allow you to <span class="emphasis"><em>inject</em></span> |
| entity managers into your session beans using the <code class="literal">PersistenceContext |
| </code> annotation. See your application server documentation for details. |
