Hi Patrick Linskey,
We are using "Enhancing at Build Time" and modified our Build.xml and included
the following in Build.xml file
<target name="enhance">
<!-- define the openjpac task; this can be done at the top of the -->
<!-- build.xml file, so it will be available for all targets -->
<taskdef name="openjpac" classpathref="dao.classpath"
classname="org.apache.openjpa.ant.PCEnhancerTask"/>
<!-- invoke enhancer on all .java files below the model directory -->
<openjpac>
<fileset dir="${src-server.dir}/host">
<include name="*.java" />
</fileset>
</openjpac>
</target>
and the following error is getting displayed. Persistence.xml file is available
in the META-INF folder.
[openjpac] <0.9.7-incubating fatal user error>
org.apache.openjpa.util.MetaDataException: MetaDataFactory could not be
configured (conf.newMetaDataFactoryInstance() returned null). This might mean
that no configuration properties were found. Ensure that you have a
META-INF/persistence.xml file, that it is available in your classpath, or that
the properties file you are using for configuration is available. If you are
using Ant, please see the <properties> or <propertiesFile> attributes of the
task's nested <config> element. This can also occur if your OpenJPA
distribution jars are corrupt, or if your security policy is overly strict.

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

Can you please help in this regard.
Thanks in advance.
Waiting for your response.
