Cannot find the declaration of element 'persistence'

Question

I have the following persistence

There is a code snippet:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="ProcedimientosAlmacenados">
    <jta-data-source>java:/jdbc/DesaAppDS</jta-data-source>
    <properties> 
        <property name="hibernate.show_sql" value="false" />
        <property name="hibernate.format_sql" value="true" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
        <property name="hibernate.hbm2ddl.auto" value="validate" />
        <property name="hibernate.ejb.entitymanager_factory_name" value="ProcedimientosAlmacenados" />
        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform" />
        <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="openjpa.TransactionMode" value="managed" />
        <property name="openjpa.ConnectionFactoryMode" value="managed" />
        <property name="openjpa.jdbc.DBDictionary" value="db2" />
        <property name="eclipselink.jdbc.batch-writing" value="JDBC"/>
    </properties>
</persistence-unit>
</persistence>

invoke persistent follows

EntityManagerFactory enfactory = Persistence.createEntityManagerFactory("ProcedimientosAlmacenados");
    EntityManager enmanager = enfactory.createEntityManager();

I jump the following error

Caused by: javax.persistence.PersistenceException: Invalid persistence.xml.
Error parsing XML (line-1 : column -1): cvc-elt.1: Cannot find the declaration of element 'persistence'.

Help me please!!!

This question was answered here

This is the summary. The problem is that you mix JPA 2.0 and JPA 2.1 notation

Either this

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
                                 http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
  version="2.1">

for JPA 2.1 or this

<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_2_0.xsd"
  version="2.0">

for JPA 2 but not a mix thereof.

See http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/index.html for details.

which is the desire to use JPA 2.1, I find no difference with my persistence – William Morales Dec 14 '15 at 14:46
can you help me with something more specific please do not encounter the problem – William Morales Dec 14 '15 at 15:24
I struggled with this for about half a day and your answer helped as I was specifying JPA 2.1 but it turned out Eclipse or the JPA facet wanted JPA 2.0 O_o – JGlass Oct 21 '19 at 20:13

Your namespace declaration is wrong.

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
             version="2.1">
    ...
</persistence>

the review and is equal to that you send me only change the order – William Morales Dec 14 '15 at 14:42
@WilliamMorales Sorry my mistake. Incomplete copied your declaration for comparision. Could it be that you rather need to use `JPA 2.0` instead? See the answer from "claspina". What hibernate version do you use? JPA 2.1 is supported only by version >= 4.3.11. – SubOptimal Dec 14 '15 at 14:53
