Hmm, ok not working still.  I think I remember now switching from 
PersistenceContext to PersistenceUnit because the former was making 
errors on me too.

Here's the full persistence.xml file (it's short).

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 
xmlns="http://java.sun.com/xml/ns/persistence" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
   <persistence-unit name="techDarwinia2PU" transaction-type="JTA">
     <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
     <jta-data-source>jdbc/techdarwinia</jta-data-source>
     <exclude-unlisted-classes>false</exclude-unlisted-classes>
     <properties>
       <property name="eclipselink.ddl-generation" value="create-tables"/>
     </properties>
   </persistence-unit>
</persistence>


Here's the error I'm getting now:

which now moves the error up to the em.persist( post ); line, one above 
the previous error at the line em.flush();

Here's what I changed the PostService to:

import com.techdarwinia.website.dto.Post;
import javax.ejb.Stateless;
import javax.faces.bean.ManagedBean;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

/**
  *
  * @author Brenden
  */
@ManagedBean
@Stateless
public class PostService
{

    @PersistenceContext
    EntityManager em;

    public void createPost( Post post )
    {
       em.persist( post );
       em.flush();
    }
}

Anyone got ideas?
