I test it in a very ! Simple Program. Just one Servlet and One Entity, her ist my Code. I hope somebody could help me.
Entity:
@Entity
@Table(name="dreminder")
public class Dreminder implements Serializable {
     @Id
     @GeneratedValue
     private int id;
....+ getter & setter
My Servlet:
@PersistenceUnit
     private EntityManagerFactory factory = Persistence.createEntityManagerFactory("default");
     @Override
     protected void service(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException {
          EntityManager em = factory.createEntityManager();
          Query query;
          query = em.createNativeQuery("select * from Dreminder", Dreminder.class);
          for (Dreminder reminder:(List<Dreminder>) query.getResultList()) {
               arg1.getWriter().write("ID: " + reminder.getId());
          em.close();
my Persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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_1_0.xsd">
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<class>dd.entities.Dreminder</class>
<properties>
<property name="toplink.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver"/>
<property name="toplink.jdbc.url" value="jdbc:derby:C:\DerbyDatabases\dreminder2;create=true"/>
<property name="toplink.jdbc.user" value="admin"/>
<property name="toplink.jdbc.password" value="admin123"/>
<property name="toplink.logging.level" value="INFO"/>
</properties>
</persistence-unit>
</persistence>
thanks for helping !!!

Answer 1

...have the first mistake...i really don't know where eclipse has stored the Persistence-Unit name "default", but if i change it in persistence.xml, he get the Factory i thing. But now i have my old Problem: "missing deployment descriptor" (only with eclipse)
