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)
| at org.jboss.seam.Component.inject(Component.java:1302)
