Oracle and the Java Community Process (JCP) members today announced the availability of Java Platform, Enterprise Edition 7 (Java EE 7) and the Java EE 7 Software Development Kit (SDK). You can join the Java EE 7 launch webcasts today, June 12, 2013 at 9:00 a.m. PT and 9:00 p.m. PT.
Java EE 7 includes
- A scalable infrastructure that facilitates building HTML5 applications by reducing response times through low-latency, bi-directional communication with WebSockets; simplifying data parsing and exchange using industry-standard JSON processing and supporting many more concurrent users through asynchronous RESTful Web Services with JAX-RS 2.0.
- A simplified application architecture with a cohesive, integrated platform; reduces boiler-plate code using dependency injection and default resources; broadens the use of annotations to increase efficiency; and enhances application portability with standard RESTful Web Services client support.
- New features that meet the most demanding enterprise requirements, such as breaking down batch jobs into manageable chunks for uninterrupted OLTP performance; defining multithreaded concurrent tasks easily for improved scalability; improving Managed Beans alignment (including transactional interceptors) and delivering transactional applications with choice and flexibility.
- Updates to Java Message Service (JMS) 2.0 improve usability through annotations and Contexts and Dependency Injection (CDI) Beans support; significantly reduce the code required to send and receive messages.
- Hands-on a tutorials, sample code and API documentation are part of the Java EE 7 SDK.
A complete list of all the new features and capabilities of Java EE 7 is available here.
The standard in community-driven enterprise software, Java EE 7 is the result of industry-wide development involving open review, ongoing builds and extensive collaboration between hundreds of engineers from more than 30 companies within the Java Community Process (JCP). Java user groups around the world have taken part in the “Adopt a JSR” program, providing valuable feedback and code samples to validate Java Specification Request (JSR) APIs.
Java EE 7 makes it easier to code, support HTML 5, and meet the most demanding enterprise requirements. The Java EE 7 SDK is ready to download today.

Part Two of Nigel Deakin’s series on JMS 2.0 (Java Message Service), titled “What's New in JMS 2.0, Part Two—New Messaging Features,” is now up on otn/java. While Part One looked at new ease-of-use features introduced in JMS 2.0, Part Two explores five important new messaging features.
First, a new kind of topic subscription called a shared subscription now allows for multiple consumers on the same topic subscription.
Second, developers can now specify a delivery delay on a message so that the JMS provider will not deliver the message until after the specified delivery delay has elapsed
Third, with JMS 2.0, users can send a message asynchronously. As Deakin explains, “This feature is available for applications running in Java SE or the Java EE application client container. It is not available to applications that run in the Java EE Web or EJB container.” According to Deakin, “When a message is sent asynchronously, the send method sends the message to the server and then returns control to the application without waiting for a reply from the server. Instead of being blocked unproductively while the JMS client waits for a reply, the application can do something useful, such as sending a further message or performing some processing.”
Deakin explains that there are two main ways in which you might use an asynchronous send in an application:
* To allow the application to do something else (such as update the display or write to a database) during the interval when it would otherwise be waiting for a reply from the server
* To allow a large number of messages to be sent in succession without waiting for a reply from the server after each message
Fourth, JMS 2.0 allows applications that receive a message to determine how many times the message has been redelivered.
And finally, a Java EE application that needs to receive messages asynchronously does so using an MDB, or message-driven bean, which is configured by specifying a number of configuration properties.

JavaOne India was a opportunity to touch base with Java developers in India, and get a sense of the developer community there. What impressed me about India is the scale: there are so many people and so many developers! I got a chance to talk to some of them at the OTN lounge. Sit back and enjoy:
JUGChennai founder Raj Hegde discusses the Money and Currency API, Adopt A JSR, and JUGChennai.
Java Champion Hardshad Oak shares his views on the Oracle Java Cloud and the Indian Java developer community.
Gurpreet Sachdeva, Director of Technology at Aricent, discusses Java G1, the Java garbage collector, and situations when it is best to use G1.
Jitendra Chittoda discusses Java concurrency and the Dehli JUG.
The rest of the videos from JavaOne are on the Java Channel on YouTube:
- Ashwin Rao discusses how NetBeans is cutting-edge tool for cutting-edge Java.
- Lakshmi Narasimhan, IBM Java Technical Lead, discusses Project Penrose.
- Jim Weaver discusses JavaFX, the state of JavaFX 3-D, and why he likes developers in India.
- Adriaan de Jonge discusses speeding up the development process, the continuous delivery of software, and the Hindi concept of Jugaad.
- Willlam Louth discusses signals, boundries, and developing self-adaptive software libraries.
- Shailesh Shivakumar of InfoSys discusses why Java projects fail and what you can do to prevent it.
After watching these, I'm sure you'll agree that the Java developer community in India is big, multifaceted, and on the move.
