- Camel 2.0M3
- Camel-JPA 2.0M3 - Weblogic 10 - Hibernate-Core 3.3.0.SP1 - Hibernate-EntityManager 3.4.0.GA - Configuration in Spring XML Hi, I tried to make use of the jpa component. But I have problems to get an EntityManagerFactory from JNDI on Weblogic 10. As described in the Spring JPA Documentation I do a JNDI-Lookup. persistence-unit-ref entries are defined in the Java EE deployment descriptor (ejb-jar.xml).

Hi
That is the same s*** with the J2ee servers and the JNDI lookup. Its painful when it does not work and you need to setup all kind of indirections in various deployment descriptors both standard j2ee related and server specific. I will try googling and look at WebLogic documentation as its a pure WebLogic + Spring J2ee lookup thingy.

Hi Claus,
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.

Doesn't work on Weblogic. There is no way to get the EntityManager from JNDI with Camel/Spring. Here is the answer from the Oracle-Support: "According the EJB3 specification, you need to lookup the entitymanagerfactory from the same container (from any servlet or session bean running on that container)." On Weblogic you can only obtain the EntityManagerFacotry if you are "inside" an Session bean or an Servlet. So no chance to do a lookup with <jee:jndi-lookup> in my camel-context.xml (Spring Bases XML Configuration) Regards, Bernd |

How do you configure / setup this? >And how do you get the Entity registered in the first place? Sorry Claus my mistake when I wrote this Message. I mean EntityManagerFactory and not Entity. I have corrected my Message. I have sent the Oracle-Support an example Testcase so that they can see what i want to do. I my case lookup the EntityManagerFactory from an "client". An POJO like Camel/Spring. The answer I got was that it is not possible on Weblogic 10.0 if you are not "inside" an Session Bean or Servlet. At the Moment, as a workaround, I use an Stateless Session Bean where the EntityManager (not the EntityManagerFactory) gets injected to persist my Entity with Camel. I would be thankfully if you have any further suggestions. Regards, Bernd |

Hi
There is an setter on JpaComponent public void setEntityManagerFactory(EntityManagerFactory entityManagerFactory) { So see the section - configuring entity manager factory at http://camel.apache.org/jpa And have that EntityManagerFactory looked up in JNDI. Spring have some jndi lookup thingy you can use to lookup name it with an id you can refer to from that camel jpa component.
