+      <para>A plain JPA setup requires all annotation mapped entity classes
+      listed in <filename>orm.xml</filename>. Same applies to XML mapping
+      files. Spring Data JPA provides a
+      <classname>ClasspathScanningPersistenceUnitPostProcessor</classname>
+      that gets a base package configured and optionally takes a mapping
+      filename pattern. It will then scan the given package for classes
+      annotated with <interfacename>@Entity</interfacename> or
+      <interfacename>@MappedSuperclass</interfacename> and also loads the
+      configuration files matching the filename pattern and hands them to the
+      JPA configuration. The PostProcessor has to be configured like
