NoInitialContextException when deploying MDB on custom resource adapter

I developed a resource adapter that I would like to use within my application ear, deployed in JBoss 5.1. After playing around with annotations and xml files, I came up with the following setup.

ejb-jar.xml

<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" version="3.0">

            <transaction-type>Bean</transaction-type>
        </message-driven>
    </enterprise-beans>
</ejb-jar>

</jboss>

MyUpdateService

@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class EuronextUpdateService implements MulticastListener, MessageDrivenBean  {
   [snip]
}

I also tried most combinations of annotations as opposed to xml files, however, I always get the same result: All beans are deployed fine, also the MyUpdateService bean. The resource adapter does send messages to my bean, which can process it just fine.

While I can work with the adapter like this, I do get the following exception in my log, which I really would like to get rid of:

Any ideas?
