Workflow (e.g. JBoss jBPM) is great – it allows you to take spaghetti code and draw it as a workflow diagram (flowchart) so that it can be reviewed by the business (the nice people who pay our wages). You then attach standard (Java) actions to these steps.
Only problem is when you come to a decision node (the one circled in red below): How do you decide to go left or right (in the workflow)? Normally this is coded in Java – good for us, but hidden from those nice business people (which means that this is more room for errors-in-translation).
Business Rules allow you to keep those decision making rules in Plain English: When something is true , then do this. That’s it. The rule engine does most of the hard work.
Integrating Workflow and Rules is easy. Use JBoss Seam (link) or do it by hand (link). And it works on non-JBoss web / app servers such as Websphere, Oracle Application Server, Tomcat and Weblogic.
Repeat x6 : Use workflow and rules. Use workflow and rules …
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.
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.
Most custom Enterprise software is written in (or uses a large element of) Enterprise Java.
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 08:3010th 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!
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.
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.
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.
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?
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.
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.
Flash is created by cool people who wear black and use Apple Macs. If you’re not sure as to what flash is, the chances are that if you’ve seen something on the web recently that made you go ‘wow’ for it’s coolness, then it was built using Adobe Flash.
To add substance to this froth Java people can use Flash (instead of normal web pages) to create cool pages that do useful stuff. For example Google Analytics uses Java and Flash to create a stunning User Interface. Even though Ajax and DHTML give you a lot of interactivity on your web pages, Flash goes one better at the small cost of not being as good for SEO and requiring a plugin (that most people already have installed).
So, what are you to do if you want to combine the coolness of Flash with the heavy lifting of Enterprise Java on the Server? The two main options are:
Flex from Adobe is one way for Java people to create flash. The core toolkit is free, but the editor costs about $500 and that’s before you pay for using it on your servers. More details in the previous blogposts on Adobe Apollo and Adobe Flex.
Open Laszlo Project is open source all the way, but does’t have a drag and drop editor (i.e. it’s more technical than graphical). Still , it allows you to create some cool effects , such as this Flash Clock.
More (In progess) notes on Open Java and Flash are on the wiki. In an impulse buy , I bought the OpenLaszlo in Action yesterday. As an EBook , with rebate (coupon LZ35607 before the end of August) it costs about 10 Euro. Initial impressions are good (both for the book and Open Laszlo) , but I’m still working my way through it (so don’t quote me on it).
Disclaimer: I get a rebate if you buy the book from Amazon, but not if you buy the (Cheaper) E-Book direct from Manning. I bought the E-Book this time, but have got free books from Manning in the past for having reviewed (as yet unpublished) JBoss items.
From Jake, organiser of the Dublin Java User Group.
Subject: Conference Announcement – Call for Speakers
From: Jakub Korab Date: August 15, 2007 06:41 AM R
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 .
(Struts is one of the most popular way for companies to build their websites. This was to be posted on Bill moaning about Struts 1 problems, but Bill’s blog isn’t accepting comments at the moment.)
Bill,
I hate to spoil your Struts 1 party , but most of these problems have been known for some time (and the Struts team would be the first to articulate them). Struts 2 is a huge improvement and , as you mention, there are good alternatives out there (including Spring MVC).
The problem is that migration from Struts 1 to (for example) Struts 2 , while easy, still carries a risk for the project in question. It can be hard to convince the business decision maker when all they see is pain (‘so you’re going to break the existing site?‘) for very little gain (‘where’s the immediate payback of upgrading?‘).
My advice is to stick with Struts 1 on existing projects. Use Struts 2 (or even better, Appfuse) on new projects. And for new code on existing projects, consider running them both side by side. They’re all tried and tested solutions.
