Work on Java EE 7 presses on under JSR 342. Things are shaping up nicely and Java EE 7 is now in the Early Draft Review stage. In beginning of November Oracle posted a little community survey about upcoming Java EE 7 features. Yesterday the results were published.
Over 1,100 developers participated in the survey and there was a large number of thoughtful comments to almost every question asked. Compare the prepared PDF attached to the EG mailing-list discussion.
New APIs for the Java EE 7 Profiles
We have a couple of new and upcoming APIs which needs to be incorporated into either the Full or the Web Profile. Namely this are WebSocket 1.0, JSON-P 1.0, Batch 1.0 and JCache 1.0. The community was asked in which profile those should end up. The results about which of them should be in the Full Profile:
As the graph depicts, support is relatively the weakest for Batch 1.0, but still good. A lot of folks saw JSON-P and WebSocket 1.0 as a critical technology.
The same for both with regards to the Web Profile. Support for adding JCache 1.0 and Batch 1.0 is relatively weak. Batch got 51.8% ‘No’ votes.
Enabling CDI by Default
The majority (73.3%) of developers support enabling CDI by default. Also the detailed comments reflect a strong general support for CDI as well as a desire for better Java EE alignment with CDI.
Consistent Usage of @Inject
A light majority (53.3%) of developers support using @Inject consistently across all Java EE JSRs. 28.8% still believe using custom injection annotations is ok. The remaining 18.0% were not sure about the right way to go. The vast majority of commenters were strongly supportive of CDI and general Java EE alignment with CDI.
Expanding the Use of @Stereotype
62.3% of the attending developers support expanding the use of @Stereotype across Java EE. A majority of the comments express ideas about general CDI/Java EE alignment.
Expanding Interceptor Use
96.3% of developers wanted to expand interceptor use to all Java EE components. 35.7% even wanted to expand interceptors to other Java EE managed classes. Most developers (54.9%) were not sure if there is any place that injection is supported that should not support interceptors. 32.8% thought any place that supports injection should also support interceptors. The remaining 12.2% were certain that there are places where injection should be supported but not interceptors.
Thanks for taking the time answering the survey. This gives a solid decision base for moving on with Java EE 7. Keep the feedback coming and subscribe to the email@example.com alias (see archives online)!
