Python, XML, and databases

People who read this blog regularly (all two of you) might know that my day job involves lots of “enterprise” level technology such as Java, JEE, Spring, heavy duty messaging systems, and Webservices, both of the limber REST species as well as the well-lumbering SOAP type. Also the more attentive reader of the pair of […]

Spring, JPA/JTA, and multiple persistence units, with view transactions

I have grappled with this topic before. Tonight, after 13 hours of struggle, I finally got my web app perfected in this regard. It all started when I needed to start the Transaction out in the view, i.e. as soon as the resource is opened on the HTTP side (rather than when the database service […]

REST-based architectural style, a big winner

Recently been deeply stuck in building software (apart from starting my PhD part-time). A long time ago I wrote about dynamically loading Spring contexts and component discovery – this system I’ve been building is an evolution of that one. We decided to adopt an most REST-based style to integrate between our components. Now, “run-time” discovery […]

REST and SOA and Agile and Waterfall

Recently I’ve been working on two projects. They are an exercise in contrasts. First the technologies and the development methodologies. So the first company uses a very Waterfall process and the integration platform is SOA. We’ve managed to build, in the middle of this, a small and focussed Java component that uses JMS in and […]

Tapestry 5 web framework

Lately I’ve been writing a Tapestry 5 based web application. I’ve used it before for a smaller application but this is the first time I’ve used it on a larger project. In a number of ways it is a very powerful framework to write web applications. The basics of Tapestry is that it is a […]

In those OTHER multiverses, Oracle already bought it for $500mil

Strange IM conversation came my way the other night, whilst discussing some code a team I led wrote at a previous workplace, I think it highlights some crucial factors Oracle bring to the Enterprise Java World: anon 9:04PM [about that code] crazymcphee 9:05 PM well, it WAS perfect … CRAZY perfect anon 9:06 PM lol… […]

GUI builders, modern development practices, and vendor lock-in

The Paranoid Engineer has declared ‘Screw All Gui Builders‘, with an excellent example of the genre of code that can be produced by one such tool, contrasted against the much nicer hand-written code. Now I can certainly sympathise with his pain. The thing that really gets my goat up, and the subject of this post, […]

‘Disappeared’ DAO layers

Adam Bien still wants to believe that a JPA layer can directly replace a formal ‘DAO layer’. And I still disagree. I might agree that for simple enough systems, it could end up being that in fact the service layers end up with PersistenceManager logic directly in their methods. But then I might say a […]

Is Java “architecture” irrelevant?

Simon Mittag says that Java Architecture is becoming irrelevant. I am now a contractor for a large government organisation and as part of my role there, I get to participate in these workshops. Trust me, a fruitless exercise. People bickering about their favourite frameworks, why to use Axis over Spring-WS, why everyone should use maven […]

JSR286 and vendor sales teams

Eric Spiegelberg recently speculated that the new Java portal specification JSR286 was at the edge of irrelevance. And others agree. I think it’s worse than irrelevant – it’s a solution in search of a problem. I’ve worked on a successful (JSR168) portal implementation, just last year. I truly don’t see what the concept of ‘portal’ brings […]
