    toplink.ddl-generation doesn't seem to be working

      I can't get my project to persist. Why is this?
      I have a skeleton project using JSF2, EJB3, Glassfish3, JPA/toplink, Helios. When I run the deployed project, I get this error:
      +Caused by: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.DatabaseException+
      Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'test.bar' doesn't exist
      Error Code: 1146

      A blank DB called test exists on mySQL
      I have a connection pool in glassfish with a URL=jdbc:mysql://localhost:3306/test
      user=root, pass=root
      A mySQL connector jar exists in $glassfishHome/glassfish/lib

      My code is as follows:
