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.sys

stenceInfo for this pud is :

<persistence-unit>

 
<PURoot>file:/E:/NetBeansProject/EnterpriseApplication2/EnterpriseApplication

        <name>myEntityManager</name>

ovider>

        <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!
