I’m trying to get this JPA + EJB + Facelets example running in TomEE Web Profile.
Because the sample uses EclipseLink, I downloaded EclipseLink and copied eclipselink/jlib/eclipselink.jar into the TomEE/lib directory.
Question 1: Is this the only file I need to copy over?
I have a number of Entity classes, one JSF SessionScoped ManagedBean to serve web requests, one Stateful EJB to handle database requests, and one more EJB that loads data into the database on start-up.
Code snippets of the ManagedBean and Stateful EJB are below:
@Singleton
@Startup
public class ConfigBean {
@EJB
private RequestBean request;
@PostConstruct
public void createData() {
request.createPart("1234-5678-01", 1, "ABC PART", new java.util.Date(),
"PARTQWERTYUIOPASXDCFVGBHNJMKL", null);
// more code here...
}
}
@Stateful
public class RequestBean {
private static Logger logger = Logger.getLogger("order.ejb.RequestBean");
@PersistenceContext
private EntityManager em;
public void createPart(String partNumber, int revision, String description,
java.util.Date revisionDate, String specification,
Serializable drawing) {
try {
Part part = new Part(partNumber, revision, description,
revisionDate, specification, drawing);
em.persist(part); // <--- EXCEPTION THROWN HERE
} catch (Exception ex) {
throw new EJBException(ex.getMessage());
}
}
}
When the line em.persist(part); in RequestBean tries to execute, I get the following exception:
WARNING: Injection: No such property 'order.ejb.RequestBean/em' in class order.ejb.RequestBean

As I’m not very familiar with the magic that is Java EE I have almost no idea what is going wrong here, but I’d love to know what is causing the first line in the stack trace, above:
WARNING: Injection: No such property 'order.ejb.RequestBean/em' in class order.ejb.RequestBean
Question 2: For some reason injection of the Entity Manager doesn’t seem to be working. Anyone have any idea why?
For completeness, below is my persistence.xml, which is in the project/src/main/webapp/classes/META-INF/ directory:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

value="both" />
</properties>
</persistence-unit>
</persistence>
Source Code
In case anyone wants to see the directory structure, source code, configuration files, etc. of the project, I’ve uploaded it to github here.
Updated
persistence.xmlto use OpenJPA, according to Common PersistenceProvider properties:Still got the following exception:
Apparently that’s a known bug in TomEE 1.0.0 that has been resolved in trunk, so I downloaded the latest beta3 snapshot
Now everything runs fine.
