JNDI lookup in OpenJPA.
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.

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?

Hi Patrick Linskey,
We are using "Enhancing at Build Time" and modified our Build.xml and included the following in Build.xml file

<!-- define the openjpac task; this can be done at the top of the -->
<!-- build.xml file, so it will be available for all targets -->

and the following error is getting displayed. Persistence.xml file is available in the META-INF folder.

This might mean that no configuration properties were found.

If you are using Ant, please see the <properties> or <propertiesFile> attributes of the task's nested <config> element.

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.

So Please help us to make an entity readonly in an application.
The following is the tag in our existing hibernate mapping file. We are replacing the hibernate code with OpenJPA code
<hibernate-mapping>
<class name="com.vormetric.server.dao.user.RoleDTO" table="CGSS_ROLE">
<cache usage="read-only"/>
So please help us as soon as possible, to make an entity readonly.
Thanks,
Praveen Kumar.
Re: JNDI lookup in OpenJPA.
Posted by Murali <mu...@emagia.com>.
Hi Patrick Linskey,
We are facing problems while retreiving the data from Persistent storage using OpenJPA. From the same java file we are able to perform Insert & Delete operations.
Please find the attached zip file(src.zip) which consists of the code(UserDTO.java, RoleDTO.java and UserDAOImpl.java) of our application.
I am also mailing exception trace files (recv.log & server.log) files.
and also "persistence.xml" mapping file for OpenJPA.
Please help us in this regard.
We are eagerly waiting for your reply.
thanks in advance.

Murali Krishna Adiraju.
RE: Exception while retrieving the data from database
Posted by Pinaki Poddar <pp...@bea.com>.
1. The code snippet and the class definitions as presented in the email
worked without error with MySQL. The error possibly in somewhere else.
2. The failure suggests NPE caused by JBoss not finding a class
(LongId?) -- can you switch type of A.id to long from Long and try?
3. Looks like your code is querying the extent of B and then deleting
each instance. Please note that JPA supports delete by query which
avoids fetching instances in memory before deleting them.
4. Instances of class B as described here will be stored in the same
table defined for A -- no need to specify it explictly
5. please post to open-jpa mailing list directly and *not* directly to
my mail address.

RE: JNDI lookup in OpenJPA.
Posted by Pinaki Poddar <pp...@bea.com>.
Hello,
> We are trying to understand the meaning of "Enhancing the DTO object
to Persistence capabilities" as observed in the trace of the exception.
OpenJPA needs to "enhance" the Java classes to be stored in a database.
Enhancement means modification of original Java class bytecode with
special
instructions. The classes can be enhanced in following ways:
1. Build-time: After the Java class has been compiled, run
$ java org.apache.openjpa.enhance.PCEnhancer -properties <path to
persistence.xml>
The enhancer program supports several other options (refer
http://incubator.apache.org/openjpa/docs/latest/manual/manual.html#ref_g
uide_pc_enhance)
This will overwrite the bytecodes of the Java classes (you can simply
notice them by growing size of *.class files or disassemble through
javap or jad to see what
code/methods have been added to the original).
The same enhancer can be invoked through an Ant task to integrate
the enhancement step in build/package/deploy process.
2. Runtime: Invoke Java runtime of your OpenJPA application with
-javaagent as follows
$ java -agent /path/to/openjpa.jar com.acme.MyOpenJPAApplication
-javaagent works only with Java 1.5 or later.
Also recommended that you enumerate all the persistent Java classes
in <class> in persistence.xml e.g.
<persisetnce-unit name="...">
<class>com.acme.MyPOJO1</class>
<class>com.acme.MyPOJO2</class>
......
</persietnec-unit>

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

Hi,
Are you writing this in an EJB, or some other artifact type?

Re: JNDI lookup in OpenJPA.
Posted by Kevin Sutter <kw...@gmail.com>.
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.
