Can't get Seam to Inject objects into a REST interface
I'm developing an application on JBoss7 with Seam 2.3. I've got a REST interface that I'm trying to inject a stateless object into. Unfortunately, despite trying to inject it, and several other things (entitymanager, logger, etc...) absolutely nothing is being injected.
I've followed the instructions here:
For setting up restful web services. My code looks pretty much like the 25.4.2 example. Breaking during a method call to the interface reveals that all objects supposed to be handled by Seam are null (even those marked with create=true). So it appears that Seam is in fact not doing anything with annotated objects in the REST interface.
Interface for the REST interface:
@Local @Remote @Path("/dispatch") public interface DispatchDirectiveREST { @GET @Path("/example/dispatch-directive.rest") @Produces("application/xml") public DirectiveRequestType example(); @POST @Path("/dispatch-directive.rest") @Consumes({"application/xml","application/json"}) @Produces("text/plain") public String dispatch(DirectiveRequestType request);
Implementation (head only) of the REST interface:
@Scope(ScopeType.STATELESS)
@Name("DispatchDirectiveRESTBean")
public class DispatchDirectiveRESTBean implements DispatchDirectiveREST, Serializable {
private static final long serialVersionUID = -2994172323883717503L;
@In(create = true) private CreateDirectiveAsync createDirectiveAsync;
@In(create = true) private CreateDirectiveAysncBean createDirectiveAsyncBean;
@In private EntityManager entityManager;
@Logger private Log logger;
Application defining the REST junk:
@ApplicationPath("/rest")
public class RESTProvider extends Application {
private final static Class<?>[] interfaces = new Class<?>[]{
DispatchDirectiveRESTBean.class,
DispatchDirectiveREST2.class
};
public Set<Class<?>> getClasses() {
return new HashSet<Class<?>>(Arrays.asList(interfaces));
}
Interface defining the CreateDirectiveAsync object (what I actually want to inject):
@Local
public interface CreateDirectiveAsync extends IAsyncTask<DirectiveSeamEntity,Long>{
@Override
@Asynchronous
public Long performTask(DirectiveSeamEntity input, @Expiration Date time);
Implementation of the interface:
@Scope(ScopeType.STATELESS)
@Name("createDirectiveAsyncBean")
public class CreateDirectiveAysncBean implements CreateDirectiveAsync {
@Logger private Log log;
@In private StatusMessages statusMessages;
@In private EntityManager manager;
@Override
@Asynchronous
public Long performTask(DirectiveSeamEntity input, @Expiration Date time) {
