Okay, and is this META-INF folder available to your build environment? The
classpath that is referenced via your classpathref="dao.classpath" entry,
does that your META-INF/persistence.xml file available?

Subject: Re: JNDI lookup in OpenJPA.
Hi Patrick Linskey,
We are not writing the OpenJPA code in EJB. Our Application is basically
using Hibernate code for persistence D/B operations.
Since, Hibernate is having LGPL licensing terms we are trying to replace
Hibernate with OpenJPA which is not having any Licensing issues.
We are able to create EntityManagerFactory & EntityManager instances
without going for JNDI lookup operation.
We used the following approach:
EntityManagerFactory emFactory = Persistence.createEntityManagerFactory
("puName",System.getProperties());
EntityManager session = emFactory.createEntityManager();
But we are facing problems while persisting the DTO object. Following
the trace of the exception that we have encountered:
2007-05-16 22:05:39,796 ERROR [
com.receivables.server.dao.host.hibernate.HostGroupDAOImpl] The Security
Server failed to persist data into the repository database. Refer to
server.log for details.

We are trying to understand the meaning of "Enhancing the DTO object to
Persistence capabilities" as observed in the trace of the exception.
Can you please help in this regard.
Thanks in advance.
Waiting for your response.
