             Summary: @Resource UserTransaction should not be allowed in CMT beans
                 Key: AS7-5331
                 URL: https://issues.jboss.org/browse/AS7-5331
             Project: Application Server 7
          Issue Type: Bug
          Components: EJB, Transactions
    Affects Versions: 7.1.2.Final (EAP)
            Reporter: Dominik Pospisil
            Assignee: jaikiran pai


Currently, it seems then @Resource UserTransaction injection is allowed in CMT beans and injects
container managed transaction. In AS/EAP5 this would throw an exception which I think is correct as 
this violates EJB 3.0 & 3.1 specs.

Section 16.12 of the EJB 3.1 specification says:

The container must make the UserTransaction interface available to the enterprise beans that are
allowed to use this interface (only session and message-driven beans with bean-managed transaction
demarcation are allowed to use this interface) either through injection using the Resource annotation
or in JNDI under the name java:comp/UserTransaction, in addition to through the EJBContext
interface. The authenticationType and shareable elements of the Resource annotation
must not be specified.

In my interpretation the statement "only session and message-driven beans with bean-managed transaction
demarcation are allowed to use this interface" would mean that other beans are prohibited to use this
interface. Allowing such beans to use this interface is specification violation.
