Spring Belfast and Spring Dublin – two of the biggest Java events of the year

Posted on by paulbrowne

No apologies for over simplifying this :

  1. If you’re in business you need computer systems to support your team. Systems to find previous dealings with a customer, systems to allow your team to work together, systems to stop people finding out things that they shouldn’t.
  2. Once your business passes the 100 employee mark and is heading for ‘Enterprise’ scale, chances are you need custom software written just for you, in addition to he ‘shrink wrap’ stuff you’ve been able to get away with until now.
  3. Most custom Enterprise software is written in (or uses a large element of) Enterprise Java.
  4. Enterprise Java is hard to get started with – it’s a big and complex framework because it solves big and complex problems. The Spring framework makes it easy.

OK, so we’re Spring nuts. But nuts only because it’s solved problems for FirstPartners over the last 4 years. What we like:

  • Spring allows you to use just enough Enterprise Java to solve your problem
  • Spring complements Enterprise Java, not replaces it.
  • Spring gives you a gentle slope to using Enterprise technologies.
  • Spring works well with Java, Oracle, .Net , (J)Ruby and pretty much any mainstream technology – including most of the widespread Java Frameworks like Struts and Hibernate.

So you wait ages for one Spring Event in Ireland, then two come along at once. We’ve written about Rod Johnson speaking in Dublin on Tue March 11th. Now there is a full day Spring Event in Belfast the day before (March 10th). And it’s sponsored by Momentum NI, so it’s free. And the Hilton Hotel is right beside Belfast Central train station, so it’s easy to get to from Dublin.

The full agenda is here (more details below), but given the importance of Spring to the Enterprise world, and the fact that the top four Spring guys are speaking, we reckon that it the Enterprise event of the year. The booking form is here.

Spring Ireland 2008

10th March 08:30 10th March 17:30
Hilton Belfast, 4 Lanyon Place, Belfast (Beside Central Train station) SpringSource is proud to announce Spring Ireland 2008. Join us for a free one-day conference with presentations from the SpringSource team including a keynote from Rod Johnson.

Keynote: Spring into the Future – Rod Johnson

The Spring Framework began in 2002 with Rod’s best-selling Expert One-on-One J2EE Design and Development; one of the most influential books ever published on J2EE, Rod is recognised as one of the world’s leading authorities on Java and J2EE development.With the rapid expansion of SpringSource and move to new corporate HQ in Silicon Valley, this is a rare UK opportunity to hear Rod provide his views and explore the future of J2EE application development.

What’s New in Spring 2.5 – Sam Brannen

Sam is a lead architect at SpringSource and one of the most experienced developers within the organisation.This session provides delegates with an overview of the new features available in Spring 2.5. Specifically, highlighting the simplified and extensible configuration support provided via configuration annotations and new XML configuration namespaces, new Java 6 support, updates to Spring AOP, improved JDBC and JPA support, annotation-driven web MVC controllers, the new annotation-based TestContext framework for unit and integration tests and more!

SpringSource Professional Services – Greg Southey

Greg has built SpringSource’s UK Professional Services organisation into the leading Spring consultancy business in the world.

This is a brief resume of some of the 97 major projects completed by the UK Professional Services team in 2007. Delegates will hear about the business drivers behind some major development projects, the business issues faced and how they were resolved in partnership with the client.

Spring as a Full Stack Web Framework – David Syer

As Principal Consultant at SpringSource, Dave leads the way in the understanding of satisfying business requirements using the Spring Portfolio. His easy manner cloaks a prodigious knowledge of application development.

This session explores the “full stack” web framework trend and answers the question: how does Spring stack up? This session defines what a full-stack web framework is, then provides a fair technical comparison between a Spring-centric web development stack and the alternatives. Delegates will head about the feature-set of modern “full stack” web frameworks, and what Spring has that differentiates itself from the pack.

Spring in Ireland – Ian Graham

Ian Graham, Momentum, will explore the use of Spring in Ireland and introduce case studies from companies who are using the Spring family of products.

Round Table Discussion – Rod Johnson, Rob Harrop, Dave Syer, Sam Brannen & Greg Southey

Your chance to ask Rod and his team anything that’s on your mind regarding Spring!

Mr Spring, Rod Johnson, Speaking in Dublin March 11th

Posted on by paulbrowne

I’ve been lucky enough to have been using Spring for just over 4 years. If you don’t know what Spring is, it solves a lot of problems in complex Enterprise Java Systems. And it makes those systems more configurable; Spring makes your code like Lego blocks. Blocks that you can take apart and use again and again (no matter what the underlying technology is). And because you can take it apart, it makes your code easier to test. And testing is a good thing – the earlier you find bugs , the cheaper they are to fix.

Get the feeling that I’m a bit of a Spring fanatic? Wasn’t always that way. It took me two projects where other people had choosen Spring to convince me. And did I mention that it’s one of the most in demand skills in the Java world?

Rod Johnson (aka ‘Mr Spring’) is speaking in Dublin at the Westin hotel Dublin on the 11st March. It’s fairly central, and it’s a breakfast briefing, so you don’t even to have to arrange the day off work. More details on the event are on the Kainos Website.

Update: The registration form to sign up for the event is here.

Hibernate Event – JBoss Speaker – Westin Hotel Dublin – 15th October

Posted on by paulbrowne

Lead developer from JBoss, coming to Dublin to talk about Hibernate on 15th October. What else could you be doing that evening? Full details on Developers.ie.
Hibernate Logo

What is Hibernate? Java programs are like Lego blocks – very 3D with bumps on them to connect together. Database tables to store data are like flat sheets of paper. Hibernate is a bridge between these two very different worlds. In technical terms, it’s called Object-Relational-Mapping (ORM).

Why is it important? Hibernate is the defacto standard in the Java World, and has had huge influence on the most recent version of the EJB spec. There’s a .Net version and even competitors (such as Toplink from Oracle) are moving to the Hibernate way of doing things.

What would you like to see on an Advanced Java Course?

Posted on by paulbrowne

Most people building systems run into the following problems again and again:

  • How to capture Business rules , in a way that both the Business users and the computer can understand.
  • How to capture the flow of actions in a system, in a way that both Business users and the computer can understand. This flow is across multiple users, and may extend over days or weeks.
  • How to deliver a system to the user (e.g. Via the Web), but to give the user a rich interface , similar to what they are used to on the desktop.
  • How to maintain and enhance older systems , now that Java has been mainstream for more than years.
  • How to take advantage of the new Features afforded by Java 5 and EJB 3, and what business problems to the solve.
  • How to build components for reuse in all environments (Web , Enterprise, Command Line and Desktop).
  • How to map information in a Java System to and from a Database (Persistent Storage or Legacy System).
  • How to deliver value to the business at every point in the project.
  • How to use the many resources and solutions already available in the Java community.

It’s to address problems like these , that I’ve been asked to put together a Advanced Java training. It’s early days yet, but I’d like to get your input as to what you’d like to see on such a course.

Enterprise Java Developer Wanted

Posted on by paulbrowne

A good friend of mine needs an Enterprise Java Developer, to be based in Dublin Ireland (sorry , no Teleworking). It’s a contract position and the project is high profile and sounds quite interesting. The main reason I’m passing on it as the exact location is the only place where I cannot get to easily from Drogheda! One man’s poison is another man’s meat (or something like that).

With that information (i.e. next to none at all) I’m going to ask you if you’re interested. Yes , I could put all the buzzwords (the usual Spring , Ajax, JSF, EJB , Hibernate), but to be honest I don’t know where the technology road will take this project.

One small catch. We need to weed out all the muppets that are out there. So, you need to have been blogging about Java for the last couple of months. If you’re interested , leave a comment and I’ll pass on your details.

Google Spreadsheets Mean the end of Java

Posted on by paulbrowne

Or to be more accurate ‘Google Spreadsheets mean the end of Java as we know it’.
Google Spreadsheets Logo
Think about this. Who pays your wages Mr Java-Developer-who-has-just-had-a-couple-of-years-at-the-top-of-the-pile? Clients, or if you’re in a larger organisation , the business folks (i.e.’internal’ clients). Do you think any of them care about Java? Do any of them know what Java is? All they want is to get things done, quickly , and with as few mistakes as possible.

These business people would be happy to run their organisations on Spreadsheets. Do you remember the cartoon where Dilbert convinced the pointy haired boss that he could fly the plane using Excel? There’s more than a element of truth to this. I know of at least one US Fortune 100 company that (until recently) conducted most of it’s operations on little more than Microsoft Office and duct-tape. It worked, not very well, but it worked.

Until now , the next line would be ‘Excel (or any other type of Spreadsheet) is not secure / scalable / sharable / not web friendly’. That was until Google launched their Docs and Speadsheets. It’s an online version of Office with some spreadsheet functionality. Play with it a bit and you’ll see that there’s plenty missing. But this being Google , I’m willing to put good money on

  • (a) new features rolled out (think steamroller) and
  • (b) These Spreadsheets being massivly scalable / secure / sharable.

This being Google, there is also an API (developer page here). It’s got massive holes in it (e.g. you can’t yet use it to create a new spreadsheet). But when Microsoft bring out their version of online spreadsheets (and they will) not only will they clone the Google API (to get market share), they’ll need to go one further and introduce new features / remove the usage restrictions in order to compete.

So, secure, scalable, sharble online spreadsheets are here to stay. So lets take a look at Mr. (or Ms.) Pointy haired boss thinking about their new project:

  1. Hmm, I think we need to be able to gather which health plans our employees are enrolled in.
  2. OK, I’ll throw together a spreadsheet to show people what I want
  3. Before I’ll give to our friendly Java developer and let him ‘do’ a website from it.
    Soon I’ll just share this on Google.
  4. Great , Loads of people are now using it, I’ll just the (Ruby / PHP / Insert other language here) guy to add one or two extra features.
  5. Most Excellent. Why don’t we spin this off as a Web 2 company and sell it to EBay??

There you have it, Massively scalable , Highly secure websites (see Google Authentication API), without needing to know anything about EJB, JMX , JBoss, JDBC or any of the hard won knowledge that us Enterprise Java Developers have built up over the last 7-8 years. I’m exaggerating, but not much.

What do you think? Is Enterprise Java dead, or is Web 2 just another boost and a slightly different way of doing things for us Java people?

Enterprise Java Presentation at DCU

Posted on by paulbrowne

On Wednesday, I’m presenting on the topic of Enterprise Java at DCU (Dublin City University) , in conjunction with Trigraph.

Trigraph Logo


I’ll blog later about bits and pieces of the slides (for commercial reasons I can’t publish the full set here), but the overview is below.

Description: Success or failure in your business depends on dealing with information faster and better than your competitors. This briefing shows you how Enterprise Java tools can do this and how to apply them to your organisation. Crucially, the briefing shows you when not to use Enterprise Java and details the alternative approaches.The briefing will give delegates an overview of the Java Web development environment, how to architect and distribute multi-tier applications and how to link these components with existing sources of information using Enterprise Application Integration (EAI). Most business have substantial investments in existing and legacy IT systems and the briefing will show how to integrate these with techniques such as JMS Messaging/ MQ Series, SOAP / XML or using the Java Connector Architecture (JCA).

As well as examining the main Java Application Server vendors (including Sun , IBM , Oracle , BEA and JBoss) the briefing will detail the technology stack that they offer. This stack includes Web presentation frameworks and SOA – Service Orientated Architecture at the Front end. In the middle (Business) layer this covers the capture of Business knowledge using Business Rule Engines and workflow (BPEL). At the back (Service) layer, this includes database integration using JDBC, and the Enterprise Service Bus (ESB).

Next Version of NoUnit (a JUnit Extension)

Posted on by paulbrowne

NoUnit is an open-source code coverage tool that shows you the effectiveness of your JUnit tests.

After a suitable pause , I’m now thinking of starting work on the next version of NoUnit. Some of the features I’m thinking of including are:

  • Eclipse Plugin , so that you can run NoUnit code coverage reports as easily as you do JUnit tests in Eclipse.
  • Support for JUnit 4 and Java 1.5 Annotations
  • Support for EJB 2.0, EJB 3.0 and Spring – currently NoUnit only shows direct calls between Java classes.
  • Various outstanding bugs and change requests from users.

    • Is there anything else you think should be included? Leave your comments here.
