Problemas com o datasource no EJB

Estou tentando subir o servidor wildfly no curso de EJB mas o seguinte erro me é retornado:

08:51:08,210 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "livraria.war")]) - failure description: {

        "jboss.persistenceunit.\"livraria.war#livrariads\".__FIRST_PHASE__ is missing [jboss.naming.context.java.jboss.datasources.livrariaDS]",
        "jboss.persistenceunit.\"livraria.war#livrariads\" is missing [jboss.naming.context.java.jboss.datasources.livrariaDS]"
    ]
}

Fiz todas as configurações que dizem no curso e ainda sim não funciona,

Segue o Standalone.xml

 <datasources>
                <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

                        </xa-datasource-class>

                    </driver>

                </drivers>
            </datasources>

Segue o persistence.xml

<persistence-unit name="livrariads">

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


        <jta-data-source>java:jboss/datasources/livrariaDS</jta-data-source>


        <class>br.com.caelum.livraria.modelo.Autor</class>
        <class>br.com.caelum.livraria.modelo.Livro</class>
        <class>br.com.caelum.livraria.modelo.Usuario</class>

Toda ajuda é bem vinda,
