Hello,
The EntityManagerFactoryProvider is not database specific. There is only one implementation that is generic and is used for all databases.
Second when acquiring a EntityManagerFactory in a Java EE environment you must use either injection or JNDI lookup. The Persistence class call you have used below is only for Java SE deployments.

Subject: Help with EJB3 and Glassfish!
I have An EJB3 Entity Persistence project in NetBeans, using GlassFish .
I have in Continer configured JDBC pool and JDBC connection via MS.SQLServer .
I have META-INF/persistence.xml file like this:
<persistence xmlns="
http://java.sun.com/xml/ns/persistence">
<persistence-unit name ="myEntityManager">
<description>Sample Customer Database</description>
<jta-data-source>jdbc/DataSourse</jta-data-source>
<class>avr.Author</class>
<class>avr.Book</class>
</persistence-unit>
</persistence>
But when I deploy this project is throws Exception :
[#|2006-01-12T10:28:35.043+0300|INFO|sun-appserver-pe9.0|javax.enterprise.system.core.classloading|_ThreadID=12;_ThreadName=httpWorkerThread-4848-3;jdbc/DataSourse;|JTADSName = jdbc/DataSourse|#]

<persistence-unit>

<class-name>avr.Book</class-name>
<properties>{}</properties>
<class-loader>InstrumentableWebappClassLoader
Parent -> WebappClassLoader
delegate: true
repositories:
/WEB-INF/classes/
It uses oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider , but I need MSSql Server's EntityManagerFactoryProvider.
When I run client wthis this part of this code throws excetion
EntityManagerFactory emf = Persistence.createEntityManagerFactory("myEntityManager");
// create EntityManager
EntityManager em = emf.createEntityManager();
Exception:
javax.persistence.PersistenceException: No Persistence provider for EntityManager named myEntityManager
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:67)
Now I have queshen: How I can make correct persistence.xml file to complile project correctly and Persistence.createEntityManagerFactory find this myEntityManager.
If can you, help me!
Tamri!
