JBoss jBPM Book on its way from Packt – Java Business Process Management (Workflow)

Posted on by paulbrowne

In a previous life, I’ve been lucky to work with two very good JBoss Products – JBoss jBPM (Workflow) and JBoss Drools (Rules). Just in case you missed it; slides from the IJTC conference (jBPM), Rules presentation to the jBPM conference and of course not to forget the Rules Book. The lines between jBPM and Drools have blurred slightly, but the competing open source teams just enhance the quality of both products, and which one is best very much depends on the problem that you have at hand.

So, I’ve been asked by Packt (the guys how published my book) to review the new jBPM Developer guide book. So, not only do I get to help a fellow author (Good Karma), I get the catchup on features of jBPM I may not have used yet in my professional capacity, and I get a free book. What is there not to like?

Disclaimer – getting free copy, but am otherwise free to write good / bad / or completely off the wall ideas about it. Watch this space.

JBoss Business Rules and jBPM Workflow presentation – Dublin

Posted on by paulbrowne

Update: Shortcut to slides (pdf, with notes following) here.

Speaking at the JBoss jBPM community day tomorrow and I’m nervous. I’m nervous because I’m standing up and talking to a group of people that really know their stuff about JBoss workflow. And talking about a project (JBoss Business rules) which has a friendly rivalry with it.

So here goes

  1. Slides in Powerpoint emailed to myself (check)
  2. Slides in PDF available online (check).
  3. Slides in Open Office on laptop ready for presentation (check)

More details on the jBPM wiki if you’re interested in attending the event. Anybody give odds on the laptop bluescreen again (like what happened at the Irish Java Technologies Conference)? It’s not what happens, it’s how you deal with it.

JBoss workflow invading Dublin (Free Community Conference)

Posted on by paulbrowne

I’m not going to explain what workflow is as I’ve probably blogged enough about it already. But the JBoss Workflow (jBPM) guys are coming to Dublin on June 6th. If you’re into workflow (and if you’re doing any sort of software for large business you should be) then this is a do not miss event and we’re privileged to have it in Ireland.

The JBoss workflow guys are dream guests. They just asked for a couple of venue suggestions and they finally went for the Guinness Hopstore where Barcamp ran last year. Next thing we got was an email saying that the JBoss Workflow event was go. So for the benefit of people flying into Dublin, here’s the information we gave on where to stay and things to do if you’re making a weekend of it.

(More information on the event on Tom Baeyens Blog)

Workflow

How to get there

Dublin is pretty well served by direct flights from Europe and the US. Aer Lingus and Ryanair are the two biggest airlines flying into Dublin – but there are plenty more (list at FlightMapping.com).

Things to do

  • Tour of Guinness brewery and visit the Gravity bar (one of the highest in Dublin)
  • Dublin Pub Tour and general social scene (it’s a coincidence that the first 2 items are drink related!)
  • Tour of Scenic Wicklow Mountains and Glendalough
  • Liffey River tour by boat
  • Dublin Bus tour – including it’s Georgian buildings and coastline
  • Newgrange – 2000 years older than the pyramids, in the stunning Boyne valley
  • Windsurfing , Kayaking or Rock climbing in Viking Carlingford Fjord.
  • Trinity College Dublin, 400 years old university , right in the city centre including the 1000 year old ‘Book of Kells’
  • For the more curious , Belfast is 2hrs away by express train in Northern Ireland.
  • Get lost in Phoneix Park, the worlds largest city centre park.

Places to Stay

I don’t tend to say in Dublin hotels too much (!) but the following I know are reasonably good value (and quiet / clean)

  • 3 of the Jury’s Inn (Christchurch is just down the road from the event location, but the IFSC and Parnell Street are also good)
  • Academy hotel is ok, if slightly more expensive , if you’re stuck.
  • If you want an airport location (about 20 mins / 20 Euro Taxi from the city centre) the Premier Inn chain are pretty good.
  • Hotel Isaacs is budget but decent , central and near the main bus / train stations.
  • Morgan hotel is where the presenters were put up for the Dublin Java conference. Central but Slightly more pricey.

For people from the community, there’s also plenty of ‘budget’ backpacker type accommodation.

Business Users Creating Rules – BRMS Guide Preview (JBoss Drools)

Posted on by paulbrowne

Just looking for the Drools BRMS – Business Rules Management System Guide? – click here (pdf)

The aim of JBoss Drools (or any other Business Rules Engine) is to get knowledge out of business user’s heads and into a format where it can be copied , edited and peer reviewed , then run 24/7. Ideally, business users should be able to write these rules directly (a) to save time and (b) to reduce errors caused by a 3rd party having to to ‘translate’ these rules into code..

Drools Brms Screenshot

Drools BRMS (Business Rules Management System) is such a tool. Easily deployed into almost any Java Web or App server, it allows users to write and validate business rules that you can then pull into your Enterprise Java Application.

Because it uses the Google Web Toolkit (GWT) , even though it is a web application (i.e. zero install on client machines) it behaves and performs as fast as a desktop one. And unlike some other (Commercial) Rules Engines, it’s free to Download and use (under the Apache licence) from the JBoss site.

And now there is a guide available online. Shortly to be integrated into the existing JBoss Drools documentation a preview of the JBoss Drools BRMS guide (pdf) is now available.

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

Posted on 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?

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.
