Hi Claus, thank your for your help!
This is what the Oracle-Support says. I will try these. Hello Bernd, I tried calling you regarding the issue, however couldn't reach. As per the issue I understand that you are using trying to lookup the Entity Manager instance and you are trying to use Entity Manager Factory, but you do not wish to use injection of ....@persistencecontext. Please let me know if you are using any JPA provider (e.g. kodo, hibernate etc). In JEE the EntityManager or EntityManagerFactory can either be looked up in JNDI, or injected into a SessionBean. To look up the EntityManager in JNDI it must be published in JNDI such as through a <persistence-context-ref> in a SessionBean's ejb-jar.xml file. To inject an EntityManager or EntityManagerFactory the annotation ....@persistencecontext or ....@persistenceunit are used. For your reference I am adding both the options (annotation / non- annota) Example SessionBean ejb-jar.xml file with persistence context <?xml version="1.0" encoding="UTF-8"?> <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"; version="3.0"> <enterprise-beans> <session> <ejb-name>EmployeeService</ejb-name> <business-remote>org.acme.EmployeeService</business-remote> <ejb-class>org.acme.EmployeeServiceBean</ejb-class> <session-type>Stateless</session-type> <persistence-context-ref> <persistence-context-ref-name>persistence/acme/entity-manager</ persistence-context-ref-name> <persistence-unit-name>acme</persistence-unit-name> </persistence-context-ref> <persistence-unit-ref> <persistence-unit-ref-name>persistence/acme/factory</persistence-unit- ref-name> <persistence-unit-name>acme</persistence-unit-name> </persistence-unit-ref> </session> </enterprise-beans> </ejb-jar> Example of looking up an EntityManager in JNDI =============================================== InitialContext context = new InitialContext(); EntityManager entityManager = (EntityManager)context.lookup("java:comp/ env/persistence/acme/entity-manager"); ... Example of looking up an EntityManagerFactory in JNDI ===================================================== InitialContext context = new InitialContext(); EntityManagerFactory factory = (EntityManagerFactory)context.lookup ("java:comp/env/persistence/acme/factory"); ... Example of injecting an EntityManager and EntityManagerFactory =============================================================== ....@stateless(name="EmployeeService", mappedName="acme/EmployeeService") ....@remote(EmployeeService.class) public class EmployeeServiceBean implements EmployeeService { ....@persistencecontext(unitName="acme") private EntityManager entityManager; ....@persistenceunit(unitName="acme") private EntityManagerFactory factory; ... } Please feel free to get back to me in case of any doubt or query regarding the same.
