HHH000196

While  starting seam 2.3 application on jboss server, I found an ERROR:

11:01:37,629 ERROR [org.hibernate.internal.util.xml.ErrorLogger] (MSC service thread 1-4) HHH000196: Error parsing XML (6) : cvc-complex-type.3.1: Value '1.0' of attribute 'version' of element 'entity-mappings' is not valid with respect to the corresponding attribute use. Attribute 'version' has a fixed value of '2.0'.

The root cause of these error is the wrong version of orm.xml. On my project it used the version 1.0, while as my entity manager using JPA 2.0

<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">

Replace with

<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">
