hello im trying to create a resful application with ejb annotations
but the persistenceContext is always null when entering the websevice

the web.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

        <persistence-unit-name>MyPersistenceUnit</persistence-unit-name>
    </persistence-context-ref>
  
</web-app>


the persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence  http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="MyPersistenceUnit">
              <jta-data-source>java:/jboss/myds</jta-data-source>
       <properties> 
                   <property name="hibernate.hbm2ddl.auto"/>  
                              <!--value set to update will keep the DB between deployments-->
                              <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/mtm_schema"/>
                              <property name="javax.persistence.jdbc.user" value="root"/>
                              <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
                              <property name="javax.persistence.jdbc.password" value="admin"/>

                     </properties>
          </persistence-unit>
</persistence>


the class which provides the webservices:  Services.java begin like this:




@Produces(MediaType.APPLICATION_JSON) 
@Path("/service")
@Stateless
public class Services implements ServicesInterface{

          @PersistenceContext(name = "MyPersistenceUnit",   
                              type=PersistenceContextType.TRANSACTION)
    private EntityManager manager;


and while entering anytype of webservice function, the entitymanager called manager is null.

project structure is as follows:  https://community.jboss.org/servlet/JiveServlet/showImage/2-809402-20665/eclispe.jpg  https://community.jboss.org/servlet/JiveServlet/downloadImage/2-809402-20665/450-240/eclispe.jpg 

can anyone help me with this please?

thanks in advance, Ronny.
