Hi, I am building Spring MVC project (2.5). It runs on GlassFish v3 server and I am using Hibernate for ORM mapping from Derby database.

I am having trouble with deployment - GlassFish says : No Persistence provider for EntityManager named mvcspringPU.

Here is how I create EntityManagerFactory :

emf = Persistence.createEntityManagerFactory("mvcspringPU");

And here is my configuration file 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="mvcspringPU" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>CarsDB</jta-data-source>
    <properties>
      <property name="hibernate.hbm2ddl.auto" value="update"/>
    </properties>
  </persistence-unit>
</persistence>

I am building with NetBeans 6.8, so things like build paths should be alright (generated by IDE itself).
