[JBoss Seam] - Datasource problem
by jimcarrey
Hi,
I am using Seam / Embeddable EJB container with Tomact.
I get a strange error when the Embeddable EJB tries to initialise telling me it has already initialised the datasource. Any ideas appreciated?
Here is the stack trace:

[Beginners Corner] - Version Problem - Jboss 3.2.5 and jboss 4.0.2
by dineshg
Hi all,
I have developed a very small session bean which has a function and will return a string.
i am using ant 1.6.5 for building the .ear file
I successfully made the ear and deployed it over JBoss 3.2.5 and it deployed successfully
And when i tried to deploy the same ear in JBoss 4.0.2 it has shown me error at the deployment time itself.
Here is the Log File
[org.jboss.deployment.scanner.URLDeploymentScanner] Watch URL for: file:/E:/dinesh/jboss-4.0.2/server/default/deploy/Test.ear -> file:/E:/dinesh/jboss-4.0.2/server/default/deploy/Test.ear

[JBoss Seam] - Problem with injection in an jsf action listener
by cristi.ciuc
Hi,
I am working on a project that intends to use a lot of Seam.
Everything worked fine until we had to refactor some of the calls from <h:commandButton id="submit" actionListener="#{...}"...> to <f:actionListener ...> and noticed that the Seam injection doesn't work anymore.
I use Jboss 4.0.4GA and Seam 1.0.1, jsf-facelets 1.1.11, tomahawk 1.1.2
I will attach here snippets of the relevant source code:
First the xhtml page from where you make the call (basically you have some templates in which you have a form with buttons, and an <f:actionListener> that gets called when the user presses a button):
[...]
| <ui:composition template="/templates/crud-page-template-formatted-input.xhtml">
|
| [...ui defines here...]
|
| <ui:define name="saveButtonParams">
| <f:actionListener type="com.nortel.emp.listener.AddRoleListener" />
| </ui:define>
|
| [...]
|
| </ui:composition>
|
| </body>
| </html>
the jsf action listener being called:
@Name("addRoleListener")
| @Stateful
| public class AddRoleListener implements ActionListener{
|
| @In(value = "roleManagement", create = true, required = true)
| private RoleManagementLocal roleManagement;
|
| public void processAction(ActionEvent evt) throws AbortProcessingException {
| [...]
| EmpRole role = new EmpRole();
| [...]
| roleManagement.add(role);
| [...]
| }
|
| @Create
| public void begin() {
| }
|
| /**
| * DOCUMENT ME!
| */
| @Destroy
| @Remove
| public void destroy() {
| }
| [...]
| }
the RoleManagement bean:
@Name("roleManagement")
| @SecurityDomain("emp-mft")
| @Stateless
| public class RoleManagementBean implements RoleManagementLocal, Serializable {
| private static final long serialVersionUID = 6125466770660833929L;
| private static final transient Logger logger = LoggerFactory.getDebugLogger(RoleManagementBean.class);
| private static SecurityDataService securityDataService = null;
| @In(value = "userManagement", create = true, required = true)
| private UserManagementLocal userManagement;
| private ResourceBundle errors = ResourceBundle.getBundle("Errors");
|
| [...]
| }
The problem is that when roleManagement.add(role); (in AddRoleListener) is called, a null pointer exception is thrown (roleManagement is not injected, for what I can tell).
In console I get:
| [debugLog] com.nortel.emp.listener.AppPhaseListener: afterPhase: Start RESTORE_VIEW(1)

Note that when using in RoleManagementBean

everything is fine.
I am really stuck. I have tried adding interceptors annotation like
@Interceptors(SeamInterceptor.class)
| @Intercept(InterceptionType.AFTER_RESTORE_VIEW)
to the AddRoleListener bean (hoping to force Seam to intercept the action listener) with no result whatsoever.
For what it seems the call to the ActionListener doesn't get intercepted by Seam. If, instead of the @In annotation, I use @EJB I still get the null pointer exception.
So, what do I do wrong? From the Seam documentation :
anonymous wrote : Seam even encourages you to use session beans as JSF action listeners!
Thanks in advance,
Cristi
