Question

Unable to configure EntityManagerFactory

Answer 1

A:

16047 [31149935@qtp-23671010-1] ERROR org.hibernate.util.XMLHelper - Error parsing XML: XML InputStream(2) cvc-complex-type.3.1: Value '2.0' of attribute 'version' of element 'entity-mappings' is not valid with respect to the corresponding attribute use. Attribute 'version' has a fixed value of '1.0'.

Looks like this is error in your xml with some kind of attribute version's value.

@pascal's answer may I know why my answer is down voted. He also pointed the same thing (XML)

@jaydeep: I actually got frustrated from your answer. I know that the problem was with the xml files. But i cant clear them, and thats why i asked help here. And, what you did.

Answer 2

+2 A:

You are using a JPA 1.0 implementation, you need to provide a JPA 1.0 compliant orm.xml (note the version attribute amongst other things):

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings 
  xmlns="http://java.sun.com/xml/ns/persistence/orm"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"
  version="1.0">
  ...
</entity-mappings>

Yours probably looks like:

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings
  xmlns="http://java.sun.com/xml/ns/persistence/orm"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
  version="2.0">
  ...
</entity-mappings>

Which is correct... if you are using a JPA 2.0 provider.

But to be honest, I don't know why you are providing an orm.xml, you usually don't need an XML mapping file when using annotations.

Thanks for your reply and sorry for the orm.xml. My intense is to show the location of persistence.xml. I am not using XML mapping. That orm.xml is auto generated. Shall I remove that file?

I would try to remove the orm.xml indeed, entity-mappings is the root element of the orm.xml, that's what the error is about.

What do you mean in "if you are using a JPA 2.0 provider"? Provider means, Hibernate??

JPA is just an API. To use JPA, you need an implementation of this API and such implementations are called persistence providers (EcliseLink, Hibernate, OpenJPA). In your case, you are using Hibernate EntityManager 3.4.0.GA which is a JPA 1.0 implementation.

What I have to do to change to JPA 2.0? by adding javax.persistence_2.0.0.jar or by change the hibernate which is using JPA 2.0??

Both, you'd have to use Hibernate EntityManager 3.5+ (and its dependencies, and this includes the javax.persistence_2.0.0.jar).

@Pascal: I have added persistence.xml file in my question. My orm.xml file is empty.
