javax.persistence.PersistenceException: Invalid persistence.xml

Question

I\'m working on project with Servlet,JPA,EJB and JBoss in eclipse. As you can see in the title of my topic I have an error on my persistence.xml file but I don\'t know whi

Answer 1

Unless you didn't copy-paste the complete file, the closing tag is missing. Append

</persistence>

in your persistence.xml

EDIT

It seems that the JNDI name of your datasource is wrong. Usually it starts with : java:/

Answer 2

This error means the version of Hibernate that you're using doesn't support version="2.1" in persistence.xml. Change the version to 2.0 (and update the xsi:schemaLocation for clarity).

Answer 3

Don't set a provider value.

remove

<provider>org.hibernate.ejb.HibernatePersistence</provider> 

and try.

Answer 4

switch to

<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">
