Murali,
This is probably a question for the application server (jboss in your case)
rather than the jpa provider (openjpa). The binding of an
EntityManagerFactory into jndi is an application server (ie. container)
process, not a jpa provider process. (The same thing goes for your
datasource lookups).
Section 5.8.1 of the JPA spec outlines this requirement on the container:
5.8.1 Application-managed Persistence Contexts
When application-managed persistence contexts are used, the container must
instantiate the entity manager
factory and expose it to the application via JNDI.
I hope this information helps.

Hi,
I am new to OpenJPA technology.
I am having problems while performing JNDI lookup for the bean resources
to get the EntityManagerFactory instance.
I am trying to perform JNDI lookup operation to fetch the DataSource &
EntityManagerFactory instances to connect to the DataBase.
Following is the code snippet:
public static EntityManagerFactory getOpenJPASessionFactory(String
jndiSessionFactoryName) throws DaoException {
EntityManagerFactory emFactory = null;
try {
Context ctx = new InitialContext();
emFactory = (EntityManagerFactory) ctx.lookup
(jndiSessionFactoryName);
}catch (ClassCastException cce) {
throw new DaoException(DaoConstants.OPENJPA_FACTORY_ERROR, cce);
} catch (NamingException ne) {
throw new DaoException(DaoConstants.OPENJPA_FACTORY_ERROR, ne);
}
return emFactory;
}
When i try to get the EntityManager Instance from Factory instance, it
says "jndiSessionFactoryName" is not bound, because of this i am not able to
get the Datasource for performing the Database operations.
Following are the environment details:
Application Server: Jboss-4.0.4.GA
Operating System with version: Redhat Linux 4, with kernel version
2.6.9.42 Elsmp
OpenJPA version: 0.9.7
JDK version: Jdk 1.5.0_07
Database: IBM DB2 version 9.1
Is there any interoperability issue of OpenJPA with Jboss-4.0.4.GA?
Do we have to upgrade to any newer version of Jboss ?
Please help me in this regard.
Thanks in advance.
Waiting for your response.
Regards,
Murali Krishna Adiraju.
