NoInitialContextException

[Hamzah khammash]

Hi ,
i have face a strange thing , i created a JPA project with hibernate annotations implementation ,when i run the application it give me this error

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
	at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)

	at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:32)
	at com.jpa.model.factory.ConnectionFactory.getEntityManager(ConnectionFactory.java:11)

and then get the data i want so what is happened here ?

here is the persistence.xml which is inside src/META-INF folder :
<?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" 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_2_0.xsd"> <persistence-unit name="JPATester" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>com.jpa.model.entity.Course</class> <class>com.jpa.model.entity.Student</class> <class>com.jpa.model.entity.Phone</class> <properties> <property name="javax.persistence.jdbc.url" value="jdbc:oracle:thin:@192.168.2.11:1521:rdfbuild" /> <property name="javax.persistence.jdbc.user" value="HAMZAH" /> <property name="javax.persistence.jdbc.password" value="hamzah" /> <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver" /> <property name="hibernate.ejb.cfgfile" value="hibernate.cfg.xml" /> </properties> </persistence-unit> </persistence>


and Hibernate.cfg.xml :
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="HibernateFactory"> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <property name="hibernate.connection.url">jdbc:oracle:thin:@192.168.2.11:1521:rdfbuild</property> <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property> <property name="hibernate.connection.username">HAMZAH</property> <property name="hibernate.connection.password">hamzah</property> </session-factory> </hibernate-configuration>
I faced this problem before it caused by persistence not correctly named and didn't give any output but now is strange for me .

I get this exception every time and never search for it as my programs are all working correctly despite this error.
