[JBoss Seam] - Problems setting up Seam-managed persistence context
by sgollery
I have a small Seam (1.2.1) application running in Tomcat 5.5.23 and using Hibernate and the Embedded EJB3 container. It works so far when I inject the EntityManager like this:
@PersistenceContext
private EntityManager em;
Now I'm trying to use a Seam-managed persistence context instead. Following instructions at http://docs.jboss.com/seam/1.2.1.GA/reference/en/html/persistence.html and many other places, I added this to context.xml:
<core:managed-persistence-context name="myDatabase"
auto-create="true"
persistence-unit-jndi-name="java:/EntityManagerFactories/myData"/>
And in persistence.xml, added this to the properties list:
property name="jboss.entity.manager.factory.jndi.name"
value="java:/EntityManagerFactories/myData"/>
In one of my session beans, I added:
@In private EntityManager myDatabase;
But as soon as a method in that session bean is executed, I get this exception:
org.jboss.seam.RequiredException: In attribute requires non-null value: myBean.myDatabase
This happens even if I use:
@In(create = true)
I've also tried to use a Seam-managed Hibernate session, but I can't get that to work either.
Apparently I'm missing something. Any idea what it is?

[JBoss Seam] - Re: Seam 1.3 Alpha Deployer Problem
by gzoller
Thanks Gavin,
Ok...did that. Didn't think I carried anything over from my 1.2 app but clearly I must have. Now I don't get that exception and I can get to my login screen. Now I'm getting a different error.
This time to be sure nothing in my app is polluting things I did a "pristine" seam-gen with only the new-project target (no generate-entities) and I didn't touch the generated code at all--just loaded it straight into JBoss IDE then deployed to the 4.2 server.
The login screen is displayed. I enter junk text into the username/pw fields and hit submit. This time I get the exception below. The default generated Authenticator class named 'authenticator' is untouched from seam-gen and components.xml has the default:
| <security:identity authenticate-method="#{authenticator.authenticate}"
| security-rules="#{securityRules}"/>
|
Ideas?
Thanks,
Greg
