With great help from the organisers of QCon we have been able to secure a speaker for a special LJC event held at QCon.

We are lucky to have Arun Gupta speaking on Thursday 7th March at 18:30.

The event will be held at The Queen Elizabeth II Conference Centre.

Arun Gupta will present: Java EE 7 Platform: Boosting Productivity and Embracing HTML5

The Java EE 7 platform focuses on Productivity and HTML5. JAX-RS 2 adds a new Client API to invoke the RESTful endpoints. JMS 2 is undergoing a complete overhaul to align with improvements in the Java language. Long awaited Batch Processing API and Concurrency API are also getting added to build applications using capabilities of the platform itself. Together these APIs will allow you to be more productive by simplifying enterprise development.

WebSocket attempts to solve the issues and limitations of HTTP for real-time communication. A new API is getting added to build WebSocket driven applications. Processing JSON structures is inherent in any HTML5 applications and a new API to parse and generate JSON is being added to the platform. JavaServer Faces is adding support reusable flows and HTML5 friendly markup. There are several other improvements coming in this latest version of the platform.

The Java EE 7 platform is scheduled to release in Q2 2013. Some of the implementations are already integrated in GlassFish. This talk will provide a code-intensive introduction to the updated Java EE 7 platform. Several live demos will be shown during the talk. Don’t miss out on this session to learn all about how to leverage the new and exciting standards in building your next enterprise application.

Marc Barto is an organiser of the popular Spring of Code Meetup, which is targeted at giving open source and social change projects a stage and a development team. Having attended two Meet a Project events he recently wrote a post which included the following advice to projects at upcoming events to maximise the effectiveness of the event:

– Printing:

At events, printing hand-outs about your project including all the useful details will be a very helpful follow-up to your short presentation.

– Mentors:

Obviously I don’t have to convince anyone here on the interest of getting a mentor attached to a project. We encourage all our project owners to look for at least one mentor. They don’t have to be based in London as they can support your project by Skype.

– Documentation:

Having a basic site, a wiki or at least at decent github page with the project specs will really help convincing people your project is serious. Whatever the stage of the project is, we encourage project owners to answer the “7 evil questions”, inspired from the Knight news challenge.

– Follow up

It is key to build on the momentum created during a matchmaking event. That’s why we always schedule a Tech meetup hosted by the project owners no later than a week after the social event.

They can then meet developers again for a more hands-on event, which can sometimes be a mini-Hackathon. Try to limit the attendance to a minimum to avoid distraction/crowd management. We usually advise project owners to pair up together to organise the event and divide the brainstorming/hacking time in half for each project.

The London Java Community’s next free event is – The London Developer Sessions on Tuesday 19th February at 18:30.

This is our monthly social gathering, which incorporates members of The London Java Community and Graduate Developer Communities. This is an informal social evening most of the evening will be spent having ad-hoc informal discussions in small groups.

We are back to The Slug and Lettuce this month: 19/20 Hanover Street, London We have had some fantastic feedback from those who have attended the event at this venue before and will be holding this month’s event in the same great location. The venue has a nicely sized function room with its own private bar, there are some great offers on beer, there is free wi-fi and it’s easy to move around and chat to lots of people. Most importantly it is a friendly and relaxed environment where developers can get together to chat and network.

The event will kick off at 6:30 PM and usually goes on until around 11:30 with members coming and going at all times throughout the evening. We usually attract 50 – 70 members so it is a lively event in which members, both junior and senior, can connect in a relaxed atmosphere and set the development world to rights.

Barry or another RecWorks team member will be onsite so if anyone is looking for free recruitment advice it’s a great chance to come along for a chat.

The London Java Community’s next free event is: Bring your Performance Problems Panel on Thursday 7th February at 18:30.

Please see link for details and to sign up –

Bring your Performance Problems Panel

This event brings together some of London’s top performance experts and gives you the opportunity to ask them questions about topics of your choice. The questions could be about a variety of topics:
* Performance problems you’ve encountered when developing software.
* What methodologies should you use when diagnosing a problem?
* How to fit performance testing and tuning into your normal development methodology.
* Tools and software: anything from NoSQL databases and concurrent messaging frameworks to sun.misc.Unsafe.

In order to submit a question, just comment on this event or tweet a question with the hashtag #ljcperfpanel. The discussion should be suitable for any member to attend. The panel members are:

Peter Lawrey
Millenium Capital Partners

Innovative developer of high performance Java Systems for competitive advantage. Developer of the Java Chronicle library. 19 years experience designing, developing and supporting leading edge high performance systems. Peter’s blog has had over one million hits in the last 18 months and is a Dzone Most Valued Blogger.

Martijn Verburg

Martijn is the CTO of jClarity – a Java/JVM performance tooling company for cloud and enterprise deployments. He focuses on demystifying performance jargon and likes to get people to firstly think about the methodology of approaching a problem.  “Measure, don’t Guess”

Most of you will know him as the co-leader of the LJC where he leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programmes.

Martijn’s book “The Well-Grounded Java Developer” (with Ben Evans) was published by Manning in 2012.

His talks and presentations are in high demand by major conferences (JavaOne, Devoxx, OSCON, FOSDEM, QCon, etc). Often you’ll find him challenging the industry status quo in his alter ego “The Diabolical Developer”, which he’ll probably bring out on the panel :-).

Manik Surtani
Red Hat/JBoss

Manik Surtani is a core R&D engineer at JBoss, Red Hat’s middleware division. He is the founder of the Infinispan project, and Platform Architect of the JBoss Data Grid. He is also the spec lead of JSR 347 (Data Grids for the Java Platform), and represents Red Hat on the Expert Group of JSR 107 (Temporary caching for Java). His interests lie in cloud and distributed computing, big data and NoSQL, autonomous systems and highly available computing.

Jeremy Whiting

Jeremy Whiting is a Senior Software Engineer working at Red Hat in the JBoss middleware division. Currently in the Performance team and previously on the JBoss Transactions team. He is a technical representative for Red Hat on the Java committee of the Standardised Performance Evaluation Corporation. Participating in the the development of standardised performance benchmarks and peer review of published results. Performance analysis and tuning of open source operating systems and JEE middleware is a great challenge which he relishes.
