title: JPA 2.1 is not generating schema scripts
body: <p>I started JPA 2.1 with Hibernate, and had the following lines in my persistence.xml</p>
  
  <pre><code>&lt;property name="javax.persistence.schema-generation.scripts.action" value="drop-and-create"/&gt;
  &lt;property name="javax.persistence.schema-generation.scripts.create-target" value="META-INF/sampleCreate.ddl"/&gt;
  &lt;property name="javax.persistence.schema-generation.scripts.drop-target" value="META-INF/sampleDrop.ddl"/&gt;
  </code></pre>
  
  <p>The tables are generated into my postgres DB.</p>
  
  <p>However, there is no sampleCreate.dll in my META-INF folder, nor error.</p>
  
  <p>What is missing here? Is it generated to other folder?</p>
  
  <p>Thanks.</p>
