Novelties of Java EE 7
The Java EE 7 was developed as a Java Specification Request (JSR 342). It has
a total of 31 specifications including 4 new specifications, 10 major releases, and
9 MRs (Maintenance Releases). All these specifications are taken into account by
the GlassFish Server 4.0 (accessible via the address

The new specifications introduced in Java EE are as follows:
• Concurrency Utilities for Java EE 1.0 (

)
, for
asynchronous processing and multi-threaded tasks in Java EE application
components.
• Batch Applications for the Java Platform 1.0 (
http://jcp.org/en/jsr/de-
tail?id=352
), to perform long-running tasks and bulk operations.
• Java API for JSON Processing 1.0 (
http://jcp.org/en/jsr/detail?id=353
)
, which
provides support for JSON processing. It offers Java EE components the abil-
ity to parse, generate, transform, and query JSON format.
• Java API for WebSocket 1.0 (
http://jcp.org/en/jsr/detail?id=356
), to build We-
bSocket applications.

the following:
• Java Platform, Enterprise Edition 7 (Java EE 7) Specification (
