Hello,

Well I am working with glassfish v2.1 meantime. The tables are created now.
I was settup to derby database. Now the table are created on mysql but I
cannot persist. Can someone told why I am not able to persist and the tables
are blank? The table Place are created on my database jpa but is empty the
table because is not persisted.


this is my Test.java class

@Path("/test")
public class Test {

     @PersistenceUnit(unitName = "citespacePU")
     EntityManagerFactory emf;



       @GET
       @Produces("text/plain")
       public String getIt() throws NamingException {
           StringBuilder strb = new StringBuilder();

           Place p = new Place();
           p.setName("Roan");


           EntityManager em = emf.createEntityManager();
           em.persist(p);
.
.
.
