Seam3/Weld - Could not find Entity Manager - java

I have a project (EJB 3.0, packaged as EAR) with a view (JSF 2.0) and persistence (JPA 2.0, Hibernate) layer. To avoid the lazy initialization support and other issues I tried to introduce a Seam Managed Persistence Context with Seam 3.0.0.Final.
For this i wrote the following producer class:
import javax.enterprise.context.ConversationScoped;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceUnit;
import org.jboss.seam.solder.core.ExtensionManaged;
class PersistenceProvider {
#ExtensionManaged
#Produces
#PersistenceUnit
#ConversationScoped
private EntityManagerFactory producerField;
}
And changed the #PersistenceContext Annotation on my EntityManager fields to #Inject.
If Iam trying to use the EntityManager now I'm getting the following stacktrace:
<WARNUNG: StandardWrapperValve[Faces Servlet]: PWC1406: Servlet.service() for servlet Faces Servlet threw exception

Debugging the applicaton on Glassfish 3.1 provided me with the following insights
The entity manager is a proxy of the type
entityManager SMPC-org$jboss$seam$persistence$ManagedPersistenceContextExtension-com$example$PersistenceProvider$producerField[#javax$enterprise$context$ConversationScoped()#javax$enterprise$inject$Produces()#javax$persistence$PersistenceUnit(name=,unitName=)#org$jboss$seam$solder$core$ExtensionManaged()]_$$_WeldClientProxy
The producer field can't be found in the beans-Field of the BeanManager in the scope of the method org.jboss.seam.persistence.ManagedPersistenceContextBeanLifecycle.getEntityManagerFactory but in a BeanManager injected into my DAOs.
I tried some variations like qualifiying the producer field, trying to inject a entity manager in the view layer services and adding the unitName and/or name of my persistence unit to the #PersistenceUnit Annotation of the producer field.
Any suggestions what Im doing wrong here?


Seems like when there is no Conversation (or Session) scope active in EJB's MDB.
You need manually active one. You can do it by implementing your MDB with the following messageHandler:
#Inject
private BoundConversationContext boundConversationContext;
public void onMessage(Message message) {
BoundRequest boundRequest = null;
try {
boundRequest = new MutableBoundRequest(new HashMap<String, Object>(), new HashMap<String, Object>());
boundConversationContext.associate(boundRequest);
if (!boundConversationContext.isActive())
boundConversationContext.activate();
// DO YOUR BUSINESS LOGIC HERE
} finally {
if (boundConversationContext != null) {
if (boundRequest != null)
boundConversationContext.dissociate(boundRequest);
if (boundConversationContext.isActive()) {
boundConversationContext.deactivate();
}
}
}
}
That worked for me on Jboss 6 AS, when tried to integrate an MDB with seam persistence.

Migration Glassfish 3.1 to Payara 5 - CDI and EJB injections contexts

In order to prepare a migration from Glassfish 3 to Payara 5 I created a small PoC with two endpoints that invoke a service, one through the CDI context and the other through the EJB context.
This PoC is based on payara micro archetype and had maven-embedded-glassfish-plugin configured, this way we can deploy it on Glassfish and Payara with a maven command.
Problem 1: CDI not work on Glassfish 3.1
#RequestScoped
#Path("cdi")
public class CdiApi {
#Inject
private CdiInterface service;
#GET
public String get() {
return service.get();
}
}
public interface CdiInterface {
String get();
}
public abstract class CdiAbstract implements CdiInterface {
}
#Dependent
public class CdiService extends CdiAbstract {
public String get() {
return "CDI response";
}
}
This
curl http://localhost:8080/micro-sample-1.0-SNAPSHOT/rest/cdi
works on Payara but didn't work on Glassfish 3.1.2 with error SEVERE: The RuntimeException could not be mapped to a response, re-throwing to the HTTP container

Problem 2: Ejb implementations needs to be explicit declared
#Stateless
#Path("ejb")
public class EjbApi {
#EJB
private EjbInterface service;
#GET
public String get() {
return service.get();
}
}
#Local
public interface EjbInterface {
String get();
}
public abstract class EjbAbstract implements EjbInterface {
}
#Stateless
public class EjbService extends EjbAbstract
// Why?!
implements EjbInterface {
public String get() {
return "EJB response";
}
}
Why EjbService NEEDS to explicit declare the implementation on EJB context if extends an abstract class that already implements it?
I had this small PoC to this thread with a simple README file.

ConcurrentModificationException thrown by GlassFish 3.1.2.2 on commit of XA transaction

We have a Singleton EJB bean deployed in GlassFish 3.1.2.2 server with the following annotations:
#ConcurrencyManagement(ConcurrencyManagementType.BEAN)
#Singleton
#Startup
#Local(XXX.class)
#TransactionAttribute(TransactionAttributeType.NEVER)
The bean is injected into a servlet which calls several methods on it. Randomly, the server.log shows that there are ConcurrentModificationException thrown by random methods of the bean on commit of XA transaction.

Apparently, the method calls are attached to the container managed transaction, even though the bean is annotated with TransactionAttributeType.NEVER. My question is why is the bean still transactional and what may be causing the random occurrence of this exception.

I have debugged the GlassFish sources and found out the cause why some methods of our bean were still transactional.
The reason is that our bean has a superclass which didn't have the #TransactionAttribute annotation, therefore methods that were not overridden in our bean had the default TransactionAttributeType.REQUIRED.
How the container treats the transaction related annotations in case of inheritance is explain e. g. in this answer https://stackoverflow.com/a/5542890/5048604

Can a stateless session bean have protected final method?

I have defined a session bean base class. This class is abstract and contains protected final methods. A session implementation class extends the abstract class and defines additional methods. During deployment, Glassfish 3.1.2 server generates an exception stating that method is overridden.
abstract class AbstractSessionBean {
#PersistenceContext(unitName="primary")
private EntityManager em;
protected final EntityManager getEntityManager() {
return em;
}
}
#Startup
#Stateless
class RegistrationSessionBean extends AbstractSessionBean {
public void loadRegistration() {
...
}
}
During deployment, the glassfish server throws an exception. If I make methods of AbstractSessionBean non-final, deployment is successful.
Does this mean that session bean cannot have final methods? or is this behavior specific to Glassfish 3.1.2 only.
Exception message is:

The short answer is "yes", but the long answer is "yes in general, but no when using no-interface view". The restriction for no-interface view comes indirectly from section 3.4.4 of the EJB 3.2 specification:
Only public methods of the bean class and of any superclasses except
java.lang.Object may be invoked through the no-interface view.
Attempted invocations of methods with any other access modifiers via
the no-interface view reference must result in the
javax.ejb.EJBException.
When generating a no-interface view proxy, the EJB container must create a subclass of the EJB class and override all public methods to provide proxying behavior. However, the second sentence from the specification quote above implies that all remaining non-private methods must also be overridden in order to throw an unconditional EJBException. That said, the error message from the application server could be better.

Why will it show null pointer exception in the jsf file?

This is my jsf file
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">

</f:facet>
<h:outputText value="#{item.tourid}"/>
</h:column>
</h:dataTable>
</h:form>
</f:view>
</h:body>
</html>
This is my manage bean
public class manageBean {
private Tourpackage tour;
private List<Tourpackage> tours;
private sessionBean session;
public manageBean() {
}
public List<Tourpackage> getTours() {
return session.retrieveTour();
}
public void setTours(List<Tourpackage> tours) {
this.tours = tours;
}
}
This is my session bean
public class sessionBean {
private EntityManager em;
public List<Tourpackage> retrieveTour(){
Query query = em.createNamedQuery("Tourpackage.findAll");
return query.getResultList();
}
}
This is my entity class (exclude the variables and methods)
#NamedQueries({
#NamedQuery(name = "Reservation.findAll", query = "SELECT r FROM Reservation r"),
#NamedQuery(name = "Reservation.findByReservationid", query = "SELECT r FROM Reservation r WHERE r.reservationid = :reservationid"),
#NamedQuery(name = "Reservation.findByReservationdate", query = "SELECT r FROM Reservation r WHERE r.reservationdate = :reservationdate")})
public class Reservation implements Serializable {
Any1 here expert in JSF???
i got null pointer exception everytime i run the jsf file through netbeans, the database i used is in the netbeans. forgive me for the terrible format.

sessionBean session in your managed bean is never initialized. Turn it into an EJB if you're in a Java EE 6 environment:
#Stateless
public class sessionBean {
#PersistenceContext(unitName = "yourPersistenceContextFileName")
private EntityManager em;
//...
}
Then just call it as an EJB in your managed bean. Also, you should retrieve the data in the #PostConstruct method, not in the getter since he getter methods can be called several times](Why JSF calls getters multiple times):
#ManagedBean
#ViewScoped
public class manageBean {
#EJB
private sessionBean session;
private List<Tourpackage> tours;
#PostConstruct
public void init() {
tours = session.retrieveTour();
}
//plain getters/setters
}

There are no annotations in your code! Did you just forget to include them in your post or they are missing from the code?
At least you have to annotate manageBean as #ManagedBean (or #Named #Statefull) and add #Inject annotation to your injected objects (EntityManager and sessionBean), otherwise the container will never handle their lifetime (i.e. instantiate them for you so you don't get NPEs)

annoate your classes with #ManagedBean or add them in the faces-config.xml.
if you are using cdi annotate them with #Named.
otherwise you can not acces your via el expression.
offtopic
By convention, Java type names usually start with an uppercase letter:
manageBean -> ManageBean
sessionBean -> SessionBean

Facelet get object attribute

I try to print the name of the logged user this way:
<p>Welcome #{sessionScope.authUser.email}</p>
In the User model the get-er and set-er for the name are present.
This is the error thrown:
javax.servlet.ServletException: For input string: "email"
What am I doing wrong?

<p>Welcome #{sessionScope.authUser.name}</p>
That line of code can impossibly have thrown this exception.

...
Look, there's a ListELResolver involved. This suggests that you have somewhere something like a
#{bean.list.email}
where #{bean.list} actually returns a List and thus needs to be accessed by an integer index using the brace notation [] like as follows to get the 1st item (which in turn of course should have the email property):
#{bean.list[0].email}
Update as per your update, the real code is
<p>Welcome #{sessionScope.authUser.email}</p>
The authUser apparently implements List or extends one of its subclasses. This makes no sense for a managed bean. Remove the interface or the subclass from the managed bean class declaration. Just the following is sufficient:
#ManagedBean
#SessionScoped
public class AuthUser implements Serializable {
// ...
}
Also, although explicitly specifying the scope like as in #{sessionScope.authUser} may be helpful for self-documentary purposes, this is unnecessary. Just use #{authUser}.
Update 2 as per the comments: you seem to have manually placed an object in the session scope which is actually a List. This is fishy. Consider using a normal session scoped managed bean which you inject as a managed property in a request scoped bean which handles the login.

At first are you sure the bean exists in the session? If so, try using #{sessionScope['authUser'].name}.
