@Resource without type
I'm trying to inject a queue and a connectionfactory via @Resource field annotation into a servlet:
public class MDBSender extends javax.servlet.http.HttpServlet implements
javax.servlet.Servlet {
@Resource(name= "java:/queue/testQueue", type=javax.jms.Queue.class)
private Queue queue;
@Resource(name = "java:/jms/connectionFactory", type=javax.jms.ConnectionFactory.class)
private ConnectionFactory jmsConnectionFactory;
If I don't specify the type in the annotation JBoss throws this exception:
21:21:40,897 INFO [org.jboss.as.server.deployment] (MSC service thread 1-3) Starting deployment of "MDBSender_war-0.0.1-SNAPSHOT.

Shouldn't it be able to figure out the type by itself? From the Java Doc of @Ressource:
http://download.oracle.com/javaee/6/api/javax/annotation/Resource.html#type%28%29
The Java type of the resource. For field annotations, the default is the type of the field. For method annotations, the default is the type of the JavaBeans property. For class annotations, there is no default and this must be specified.
I'm using a nightly build 7.1.0.Alpha2 1704
Edit:
With the type in the annotation a warning still appears in the log but the application deploys:
22:21:11,444 INFO [org.jboss.as.server.deployment] (MSC service thread 1-3) Starting deployment of "MDBSender_war-0.0.1-SNAPSHOT. war" 22:21:11,475 WARN [org.jboss.as.ee.component.deployers.ResourceInjectionAnnotationParsingProcessor] (MSC service thread 1-4) Can' t handle @Resource for ENC name: java:/queue/testQueue on class ch.mobi.test.MDBSender.MDBSender since it's missing a "lookup" (or "mappedName") value and isn't of any known type 22:21:11,506 INFO [org.jboss.web] (MSC service thread 1-2) registering web context: /MDBSender_war-0.0.1-SNAPSHOT 22:21:11,522 INFO [org.jboss.as.server.controller] (DeploymentScanner-threads - 1) Replaced deployment "MDBSender_war-0.0.1-SNAPS HOT.war" with deployment "MDBSender_war-0.0.1-SNAPSHOT.war"
and the queue is null.
The queue is definitly bound in jndi:
