title: OpenJPA disabling create tables on startup
body: <p>I must use an external database in a <code>spring</code> non web application.</p>
  
  <p>How can i disable openjpa to try to create entity tables? My entities <code>EmailAddress</code> and <code>Message</code> has annotations "<code>@Entity</code>", i do not know if it is right.    </p>
  
  <pre><code>&lt;persistence-unit name="myPU" transaction-type="RESOURCE_LOCAL"&gt;
          &lt;provider&gt;org.apache.openjpa.persistence.PersistenceProviderImpl&lt;/provider&gt;
          &lt;class&gt;pack.EmailAddress&lt;/class&gt;
          &lt;class&gt;pack.Message&lt;/class&gt;
             &lt;properties&gt;
                  &lt;property name="javax.persistence.jdbc.user" value="root" /&gt;
                  &lt;property name="javax.persistence.jdbc.password" value="root" /&gt;
                  &lt;property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/kepsDb" /&gt;
                  &lt;property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" /&gt;
                  &lt;property name="openjpa.jdbc.SynchronizeMappings" value="false"/&gt;
              &lt;/properties&gt;
  
          &lt;/persistence-unit&gt;
  </code></pre>
