createEntityManagerFactory null

[tarik el berrak]

Hi all,

I have a problem with my jpa project.

here is the persistence file:
----------------------------------------------------------------------------
<persistence 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" version="1.0">
<persistence-unit name="QuotePickerPU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.quotepicker.beans.QuoteBean</class>
<class>com.quotepicker.beans.CompanyBean</class>
<class>com.quotepicker.beans.QuoteBeanId</class>
<properties>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/trainning" />
<property name="hibernate.connection.username" value="root"/>
</properties>
</persistence-unit>
----------------------------------------------------------------------------

i get null when calling this

emf = Persistence.createEntityManagerFactory("QuotePickerPU");




any ideas ??

Thanks in advance

emf = Persistence.createEntityManagerFactory("QuotePickerPU");

should always be called when outside the EJB container.

Can you let us know, are you calling it inside EJB container.

Hi Amandeep

How you say this

should always be called when outside the EJB container.

I went through the spec, But I couldn't find such restriction. That is true that we use this method for em creation outside container. But I think there is no restriction to use it in side the container

Hi Tarik,
Please let us know if your application is a stand alone application or deployed in a managed environment.
