Why is EntityManager not injected via @PersistenceContext within Tomcat8 environment?

I have some service to persist object to context and face a null EntityManager when run it

@Stateless
public class PointServies {

@PersistenceContext(name="pointProvider",type = PersistenceContextType.EXTENDED)
private EntityManager em;

public void addMovie(Point point) throws Exception {
    em.persist(point); // em is null here.
}
}

this is my persistence.xml

<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-unit name="pointProvider">

    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

    <class>model.Point</class>

    <properties>
        <!-- Configuring JDBC properties -->
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost/testdb" />
        <property name="javax.persistence.jdbc.user" value="root" />
        <property name="javax.persistence.jdbc.password" value="admin" />
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />

        <!-- Hibernate properties -->
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
        <property name="hibernate.hbm2ddl.auto" value="update" />

        <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"/>
    </properties>
</persistence-unit>

looks like PersistenceContext can't find my xml..... The persistence.xml exist in "src/META-INF/persistence.xml" and all the other sources reside in "src/model/Point"

I try to run this project on Tomcat 8 web-container.

Tomcat doesn't support EJB by default, i reccommand you either add the OpenEJB webapp to Tomcat, or use full-stack application server like GlassFish or WebLogic Server.
