java - Most promising new JSRs? -


Recently I have picked up a very useful web service framework (JX-RS aka JSR-311; And its rocket implementation implementation), and a nifty verification library ("Bean Validation API", JSR-303).

Both of these JSR relatives are new, which makes me wonder what I am missing - given that there are hundreds of JSRs, tracking them all with different levels of progress, activity and ability. It is not easy.

I have mentioned beyond that what others have promised and pay attention to

: On the OSGi model based on Dynamic Component Support for Java ™,

, it would be very interesting to integrate into Java.

But finally selected (Java module dependency) ... from the current JDK 7 implementation.

In the meantime, there are;)

As the article "representative" is described in the ions of module dependency ":

JSR One of the main differences between 291 and JSR 277 is the way in which module dependency is represented, satisfied and managed. [...] More important differences predict the behavior of the collection of modules Is related to the requirement. It is important.

  • With JSR 291 , an external management system is capable of reading dependency announcements in each module And apply these rules

  • With JSR 277 When import policies are used, the situation is very different the behavior of an import policy The only way to determine it is to execute it . But still, there is no guarantee in it If the dependencies are missing, then the import policy is not worth testing to determine how missing dependencies can be satisfied.
