EntityManager JNDI - nombre no encontrado

Hola, creé un recurso JNDI en el servidor Tomcat 7 y estoy tratando de usarlo a través de persistence.xml, pero recibí un error de que el nombre del recurso no se encuentra en el contexto. Intenté otra solución encontrada en la red, pero ninguna funcionó para mí. Alguien ve lo que está mal? Debajo de mi fragmento server.xml:

<GlobalNamingResources>
    <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users
    -->
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml"/>

    <Resource name="jdbc/myds" auth="Container"
              type="javax.sql.DataSource"
              maxActive="10" maxIdle="3" maxWait="10000"
              username="boardgames" password="boardgames"
              driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
               url="jdbc:sqlserver://localhost:1433;databaseName=boardgames;integratedSecurity=true;"

            />


</GlobalNamingResources>

También agregué referencias de recursos a web.xml:

 <resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/mydb</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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_1_0.xsd">
<persistence-unit name="persistence_sample" transaction-type="RESOURCE_LOCAL">

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


   <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    -->
    <non-jta-data-source>java:/comp/env/jdbc/myds</non-jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServer2008Dialect"/>        <!-- Enable Hibernate's automatic session context management -->
        <property name="connection.autocommit" value="false"/>
        <property name="hibernate.show_sql" value="true"/>
    </properties>

</persistence-unit>

Intento obtener el administrador de la entidad de la siguiente manera:

EntityManagerFactory emf =  Persistence.createEntityManagerFactory("persistence_sample");
EntityManager em = emf.createEntityManager();

También intenté ver si la fuente de datos no es nula y está bien (ds no es nula):

  Context initCtx = new InitialContext();
  Context envCtx = (Context) initCtx.lookup("java:comp/env");

  logger.error("ctx " + envCtx);

  DataSource ds = (DataSource)
                envCtx.lookup("jdbc/mydb");
  logger.error("ds " + ds);

Seguimiento de pila de la excepción:

1314 [http-bio-8080-exec-2] ERROR org.hibernate.connection.DatasourceConnectionProvider  - Could not find datasource: java:/comp/env/jdbc/myds
javax.naming.NameNotFoundException: Name [myds] is not bound in this Context. Unable to find [myds].
