It feels like we have building web sites and applications for centuries, doesn’t it? However, we know that this is so untrue, because the web is only 25 years old since Sir Tim Berner’s Lee great proposal at CERN. The impetus of online design and development has changed, we now talk about the Digital Worker, the Digital environment and we about building web applications and ecommerce applications that are user friendly and customer centric. So what has this all to with the humble Java application developer? The answer is everything. We must be explicit in the software that we write, lean and agile in the way we write, and whilst making sure the take full advantage of the underlying Java platform. In fact, because we have this magnificent Java Virtual Machine and open standards like Java EE, we can continue build quality, robust and sustainable software for all our stakeholders and business users.

“There has been a reinvention of the Internet
and the behaviour of users in the last few
years. Digital services are now more agile,
open and cheaper.”
Martha Lane Fox,
UK Digital Champion 2010

quantity such as voltage or magnetic polarisation.
Often contrasted with analogue.

• Division of marketing using such smartphones, tablets, desktop
computers and game consoles.
• Digital marketing (UK) and Internet Marketing (USA)
• Complement to traditional marketing: newspapers, TV, voice &

17. Is Java still relevant to Digital Development?

18. “Clear standard alternatives to Java and C# for custom-developed
applications do not exist. There are issues with many of the alternatives.
For example, BPM tools are great for defining and implementing
processes but a poor choice for implementing compelling user
experiences. The market for application dev tools is beginning to change
though. The next generation of app dev tools will:
• Dramatically increase developer productivity.
• Allow developers to delegate change to business end users.”
Mike Gualitieri
Forrester, November 2010

19. “The JVM is an ideal platform to use for long-running
server side applications. It's been battle-tested over
the last 20 years, and it’s an extremely fast, stable,
and reliable platform on which to run applications like
web servers, message queues, and other services.”
Chris Price
Dev Ops, Puppet Labs

23. Java EE 8 Survey Results #1
Should we define new APIs to deploy and
manage applications?
62.6% Yes, 11.1% No, 23.5% Don’t Know
https://java.net/downloads/javaee-spec/JavaEE8_Community_Survey_Results.pdf

24. Java EE 8 Survey Results #2
Should such new Deployment and
Management APIs be REST APIs or JMX APIs?
82.8% REST, 11.1% JMX, 6.1% Other

25. Which of these API do you think important to be included in
Java EE 8?

42. Java EE & Java SE Strengths
• Java 8 has Lambdas has functional interfaces
• Java 9 will have modularity
• 9-10 million developers world-wide
• Mature JVM – fast and strong performance
• Alternative JVM languages Scala, Clojure, Groovy and others
• Standards – DRY, NIH, YAGNI, WET
• Open Source frameworks aplenty
• It a fertile bed for competition to grow: Spring Framework and others
• Java platform has a strong steward in Oracle

43. Java Weaknesses
• Classic Java has boilerplate, but at least New Java 8
has Lambdas has functional interfaces
• Java lacks a Read-Evaluate-Print-Loop (REPL), but
alternative JVM language do have this feature
• Companies probably will drag their feet, upgrading
to the new Java sooner than later
– the classic technology adoption lifecycle of innovators,
early adopters, early and late majority; and laggards.
