Top 10 Speakers at the Irish Java Technologies Conference (IJTC Dublin)

Posted on October 25, 2007 by paulbrowne

Not (too blatant) a plug for the Irish Java Technologies Conference (IJTC). Although if you’re around Dublin on the 7th / 8th / 9th November I’m told you’re more than welcome to drop in. This post is more a quick review of the people who are speaking. It’s also an invitation to check out their websites and see if any of the technologies they are promoting could be of use to your project.

Here are the top 10 projects that I’m looking forward to checking out.

10) Java and Microsoft SQL Server : It’s still a brave Microsoft person that comes to a Java conference. Shows MS recognition a substantial amount of Java deployments persist their Data to a SQL- Server database.

9) Eclipse STP (and SOA) – Service Orientated Architecture is the buzzword of the year. If anybody can put substance behind the hype , it’s the guys From Iona.

8) Eclipse JPA and Dali. Hibernate pushed Object Relational Mapping (ORM) to be the standard approach to database access. The manager of the ‘other’ ORM Project (Oracle Toplink) should give a interesting coverage of the tooling developments.

7) Apache Geronimo – by Jeff Genender from Apache Foundation. So long the ‘other’ Open source application server, this is now becoming credible in commercial deployments.
6) Java Update – Simon has been working as a lead Java consultant for Sun Microsystems. He’ll be talking about Java Standard Edition 6 and Java Mobile Edition. But what I’m really interested in is Java Enterprise Edition 5, Scripting, Java Realtime and Java FX.

5) If scripting is your thing fellow Onjava Blogger Dejan Bosanac is also speaking on this subject. He’s talking about Scripting within the JVM, which will be one of the hot topics for 2008.

4) iPhone v JMME – I don’t get the buzz around Mobile (give it another 18 months , we’ll all be running Java Application Servers on the mobile). But many people are interested in it – this talk is how to make you Mobile Java apps as slick as those in the iPhone.

3) JBoss Drools Engine (Drools) – I’ve blogged (a little bit) about Drools before. I’ve also been fortunate enough to hear Mark Proctor speak and you will come out an convinced that the natural home for Business Logic is in the Rule engine.

2) JPA and Hibernate – There is a very strong possibility that Emmanuel Bernard will be returning to Dublin to talk about the Hibernate project that he leads. Having seen his recent talk, and given the level of interest in Hibernate, I expect a strong turnout for this one.

1) Spring 2.5 – Spring has been around for more than 5 years and is making serious inroads in the the Enterprise Java community. Sam Brannen (from Interface21) will give details on the latest on the major update to Spring (2.5) as well as what is planned for the future.

Disclaimer: I’ll be talking about Java Workflow (based on on JBoss jBPM). But compared to these guys, I’m way down on the Z-List of presenters.

You need to go to a self help group – Rules and Workflow

Posted on October 1, 2007 by paulbrowne

Picture the scene: a self help group meeting, plastic chairs arranged in a circle. Sitting on the chairs are an assortment of (mainly) men in their 20’s or 30’s. One plucks up the courage and mumbles ‘Hello, I’m Paul , and I’ve been writing bad Java code for 10 years‘.

‘When I got into Java I was using JSP for everything – HTML, talking to databases, doing workflow – anything I could get my hands on. I was young and I didn’t know what I was doing. Even after I got treatment based on EJB, Spring and Hibernate, I still feel that there is a void at the centre of my coding life‘.

‘I fell in with a bad crowd. Business types with suits and violin cases. They said they’d pay me good money if I built them something. Now they don’t believe that it works – it’s all techie stuff to them. Those boys are going to play rough if I can’t make them understand the code. What can I do?‘

There was silence for a while. Then the group leader said

It’s a tough one. Does anybody have any suggestions?

Red Hat Developer Studio – Office for Java People

Posted on September 18, 2007 by paulbrowne

I’m not going to cross post my O’Reilly Blog entry on Red Hat Developer Studio.

I’ll just give the 2 minute summary. An IDE (integrated Development Environment) is like Microsoft Office for Developers – you could use notepad instead, but an IDE makes the overall writing experience easier. Microsoft Visual Studio is the main non-Java IDE. For Java , you have the choice of Eclipse (and other tools built on it such as JBoss IDE, JBuilder ,Websphere and Weblogic studio), IntelliJ or Sun’s Netbeans. Very much a personal preference as to which is best of the three of these.

For me, I tend to use Eclipse (1) because I can install it on any client site (2) If an IDE preference is stated on a project, it tends to be Eclipse and (3) There are plugins available for almost anything – including non-Java languages such as Ruby.

Or rather , I download a version of Eclipse with all the plugins pre-packaged – which is what Red Hat Developer Studio does.

Full Install Notes on / Getting started with Red Hat Dev Studio are here.

I am happy to announce what I hope will be the first in a series of major Java events here in Dublin. In conjunction with IrishDev the Dublin JUG will be hosting the Irish Java Technologies Conference in early November. This 2-3 day event aims to bring together the big names in Java right here in Dublin.

We are currently in the process of organizing speakers for the event. If you have any suggestions of technologies/topics that you would like to hear discussed, particular speakers you would like to hear, or would like to present on a topic, please email myself or .

Apologies to the Dublin Java Meetup

Posted on March 13, 2007 by paulbrowne

Apologies to the Dublin Java Meetup. I was due to go tonight (event details). They even agreed to talk about Business Rules and Workflow in Java – a subject dear to my heart. And now I can’t go for family reasons (not as dramatic as it sounds, but enough to cancel).

Sorry Guys.

Enterprise Java Developer Wanted

Posted on February 5, 2007 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.

Irish Blogger lynched on O'Reilly site for comparing Google Spreadsheets with Java

Posted on January 19, 2007 by paulbrowne

There are times when Web2, blogging , feedback from readers and the wisdom of crowds is great. And there are times that it’s extremely painful.

Like this Blogpost I wrote over on the O’Reilly site. Do Google Spreadsheets mean the end of Java?

I expected some people to disagree with me , but at least disagree for good reasons. The key point, that Web 2, it’s applications (of which Google spreadsheets is only ) and their API’s will fundamentally change the way we solve business problems using IT has been lost in the knee-jerk reaction.

Back to the future with Java and Retroweaver

Posted on August 22, 2006 by paulbrowne

Java 5 (also known as Java 1.5) was a fairly major release that makes using Java a lot quicker , easier and cleaner (click here for a full list of the new features, including Meta-Data , concurrency, Generic Types, Profiling , integrated JMX Admin facilities and XML support as part of the java core.).

The problem is that a lot of Application Servers still require the previous (1.4) Version. Even if you’re running on a Server (such as JBoss) that does fully support Java 5, the chances are upgrading an existing application will take a lot of time , mainly in testing effort to make sure nothing has broken. As Java matures, running on older versions will become more and more of an issue.

So, how do you get the benefit of the latest features , without losing the known stability of the previous version. One solution is Retroweaver which allows you to write in Java 5, and deploy in Java 1.4.
Thanks to Joe Walker’s Blog (Him of DWR fame) for putting me on to this one.
