EJB 3.1 asynchrony and transactions
May 9, 2010 § 1 Comment
When presenting Java EE 6 and GlassFish v3 at the Lausanne JUG last week I was bombarded with questions (I like that) and I think I didn’t do an ideal job answering the following question (paraphrasing) :
How does the new async feature in EJB 3.1 work wrt transactions?
The precise answer is easy to find in the EJB 3.1 specification itself (paragraph 4.5.3) :
Client transaction context does not propagate with an asynchronous method invocation. From the Bean Developer’s view, there is never a transaction context flowing in from the client. This means, for example, that the semantics of the
REQUIREDtransaction attribute on an asynchronous method are exactly the same as
By the way, the entire section on EJB 3.1 asynchronous methods is only two pages.
