Trying to migrate from jBoss4.0.5.GA+Seam1.2.1.GA to jBoss4.2.1.GA+Seam2.0.0.B1, after updating lots of code, app deploys properly, but when I try to acces initial page, an EntityHome complains and sends me to error page:
In attribute requires non-null value: complexHome.entityManager
at this arbitrary piece of code:
@Name("complexHome")
public class ComplexHome extends GenericEntityHome<Complex> {
@In EntityManager entityManager ;
...
I believe it fails here due to life cycle but has nothing to do with this (works nice and smooth with old jBoss + old seam). App has deployed properly, logs do not report any errors, components.xml looks like this (fragment):
Components.xml (fragment)
<core:managed-persistence-context name="entityManager"
auto-create="true" persistence-unit-jndi-name="java:/EntityManagerFactories/LaboraemPersistenceFactory" />
... and EJTool's "JNDI Browser" (
http://www.ejtools.org/) reports:
java:/
ConnectionFactory (org.jboss.mq.SpyConnectionFactory)
DefaultDS
DefaultJMSProvider (org.jboss.jms.jndi.JNDIProviderAdapter)
EntityManagerFactories
LaboraemPersistenceFactory (org.jboss.ejb3.entity.InjectedEntityManagerFactory)
EntityManagers
LaboraemPersistence (org.jboss.ejb3.entity.TransactionScopedEntityManager)
JmsXA (org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl)
... (more) ...
... so, the persistence unit has been deployed, I'm using the same injection I used for old seam, as seen in examples (even seam2 examples), so I believe things should work, yet, they don't :(
Am I missing something ? Anybody ?
Here's a bit of the stacktrace:
org.jboss.seam.RequiredException: In attribute requires non-null value: complexHome.entityManager
at org.jboss.seam.Component.getValueToInject(Component.java:2042)
at org.jboss.seam.Component.injectAttributes(Component.java:1481)
