[cdi-dev] CDI have any plan to process Transaction?

Tue May 1 05:49:41 EDT 2012

I do not understand why introduce @Transational in JEE7 but it  still 
align with JTA.

In a sense, they would be "blessed" extensions, which is all any user really cares about (how else do they know what's in weld-servlet.jar, for example).

Otherwise there is not enough core services to provide a dependable and portable programming model. If you (general audience) want to use a Servlet container, you aren't using Java EE and will have to supplement with addons like CDI extensions or Spring.
