[jboss-jira] [JBoss JIRA] (WFLY-1960) CDI @Inject of @Stateless @WebService cause WELD-001408 Unsatisfied dependencies

[Martin Kouba (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12804700#comment-12804700 ] 

Martin Kouba commented on WFLY-1960:
------------------------------------

The problem is the {{TestBean}} does NOT define a local client view - it doesn't implement a business interface and does not satisfy no-interface view requirements either. It only has a *web service client view*. See also EJB spec, 4.9.8 Session Bean’s No-Interface View:
{quote}
* If the bean does not expose any other client views (local, remote, no-interface, 2.x Remote Home, 2.x Local Home, Web Service) and its implements clause is empty, the bean defines a no-interface view.
...
{quote}

Furthermore the CDI spec, 3.2.2. Bean types of a session bean:
{quote}
The unrestricted set of bean types for a session bean contains all local interfaces of the bean and their superinterfaces. If the session bean has a bean class local view, the unrestricted set of bean types contains the bean class and all superclasses.
...
{quote}

I believe that "bean class local view" is referencing EJB no-interface view (I'm not sure though and will raise a CDI spec issue). If so the set of bean types for TestBean contains only {{java.lang.Object}} and so the test deployment should result in unsatisfied dependency.

I'm not sure whether @EJB injection should work or not, but given that JAX-WS web services are accessible via JNDI it may work by coincidence.

Note that if you annotate {{TestBean}} with {{javax.ejb.LocalBean}} (explicitly state a session bean exposes a no-interface view) the test passes.
