10:30 a.m.
My question is 'why doesn't this work?' - here is the background
information...
First, I have a SLSB - userEditor:
| @Stateless
| @Name("userEditor")
| public class UserEditorBean implements UserEditor {
|
| @Logger
| private Log log;
|
| @PersistenceContext(unitName = "useridDatabase")
| private EntityManager em;
|
| ... implementation details ...
|
| }
|
Second, I have a SFSB - userManager:
| @Stateful
| @Name("userManager")
| public class UserManagerBean implements UserManager {
|
| @Logger
| private Log log;
|
| @In
| private UserEditor userEditor;
|
| @DataModel
| private List<User> users;
|
| @DataModelSelection
| @Out(required=false)
| private User user;
|
| @Factory("users")
| public void getUsers() {
| if (users == null || users.isEmpty()) {
| this.users = userEditor.getUsers();
| log.info("loaded users");
| } else {
| log.info("users already loaded");
| }
| }
|
| ... and so on ...
| }
|
In components.xml, I have:
| <component name="org.jboss.seam.core.init">
| <property name="debug">true</property>
| <property name="myFacesLifecycleBug">false</property>
| <!-- Uncomment the following property and customize as necessary if you're
using EJB3 -->
| <property
name="jndiPattern">useridentity-app-1.0/#{ejbName}/local</property>
| </component>
|
When I deploy my application .ear file, here is some (abbreviated) info from Seam:
| 11:18:42,828 INFO [Component] Component: userManager, scope: CONVERSATION, type:
STATEFUL_SESSION_BEAN, class: com.javaplant.identity.impl.UserManagerBean, JNDI: useri
| dentity-app-1.0/UserManagerBean/local
| .....
| 11:18:43,734 INFO [Component] Component: userEditor, scope: STATELESS, type:
STATELESS_SESSION_BEAN, class: com.javaplant.identity.impl.UserEditorBean, JNDI:
userident
| ity-app-1.0/UserEditorBean/local
|
And from the JBoss JMX-CONSOLE, we have:
| Global JNDI Namespace
|
| +- useridentity-app-1.0 (class: org.jnp.interfaces.NamingContext)
| | +- Dispatcher (class: org.jnp.interfaces.NamingContext)

| | | +- local (class: java.lang.Object)
| | | +- remote (class: java.lang.Object)
| | | +- remoteStatefulProxyFactory (proxy: $Proxy117 implements interface
org.jboss.ejb3.ProxyFactory)
|
I have a Facelets component in which I reference the 'users' component which is
produced by the factory method in my UserManager:
| <ice:dataTable
| var="user"
| value="#{users}"
| sortColumn="#{user.name}"
| >
| ....
| </ice:dataTable>
|
However, this is not working - here is the stack trace:
| 11:19:10,703 ERROR [D2DFaceletViewHandler] Problem in renderResponse:

So what am I missing here? I could swear I've successfully injected session beans
into each other before with Seam - however, I noticed the documentation doesn't show
an explicit example of this... is this not supported? Any help appreciated.
Thanks,
Brad Smith
