From Mikalai's Study Guide chapter 2 - part 3
While referring to the @Resource annotation, it says:
The Bean Provider can specify that connections obtained from a resource manager connection factory reference are not shareable by specifying the value of the shareable annotation element to false or the res-sharing-scope deployment descriptor element to be Unshareable.
and later in the chapter it says:
A field or a method of a bean may be annotated with the Resource annotation to request injection of a resource environment reference. The authenticationType and shareable elements of the Resource annotation MUST NOT be specified; resource environment entries are NOT shareable and DO NOT require authentication.
Is this a mistake or some misunderstanding on my part?
