C10k: Developing non-blocking REST services with Spring MVC

April 22nd, 2014 by Magnus Larsson

A first look at Spring Boot, is it time to leave XML based configuration behind?

April 15th, 2014 by Magnus Larsson

Introduction
Spring Boot makes it very easy to create Spring based applications. Spring Boot takes an opinionated view of the Spring platform and third-party libraries, allowing us to get started with a minimal configuration. For example we can develop a Jave EE based web application without any configuration files. Not even a web.xml file is required!
When [...]

A first look at Gradle, is it time to leave Maven and Ant behind?

April 14th, 2014 by Magnus Larsson

Introduction
Gradle is a build tool that tries to combine the best of Maven and Ant and at the same time replace the verbose XML syntax in these tools with a compact and easy to understand Groovy based DSL. Gradle supports Mavens default project structure, dependency management mechanism and repository infrastructure making a replacement fairly straight [...]

C10k: Lightweight Java servers for large scaled realtime WebSocket communication

August 12th, 2013 by Magnus Larsson

Introduction
According to my colleges that work with frontend technologies many of our customers have today started to use HTML5 to build single page web apps but most of them have not yet switched from old school HTTP to WebSockets when it comes to communicating with backend server applications.
WebSockets simplifies much of the complexity in HTTP [...]

RequireJS – modules, plugins and optimization

March 15th, 2013 by Kristin Luhr

In my current project we are rewriting a feature-packed Struts application into a single page web app using Backbone and Bootstrap. The need for architectural patterns is becoming more and more evident as the application grows and we realize how many different ways you can use Backbone to do the [...]

“Is REST the future for SOA?”

August 12th, 2011 by Johan Eltes

I just read Boris Lublinsky’s article on “Is REST the future for SOA?“.
I think it makes a good job in clarifying that REST and SOA are different architecture styles, rather than merely a choice of protocol. I also like that he discusses the common case where people talk about REST when they actually mean http [...]

Never let an enterprise architect into a coding dojo

September 21st, 2010 by Johan Eltes

I’m an enterprise architect. My work is to define architectures that span systems, organizations and sometimes countries. Not because architectures become better if they do. No, because business-, enterprise- and pan-european integration projects depend on an agreed abstraction (in the sense of frameworks) of IT so that focus can shift from plumbing to system-level design. [...]

June 3rd, 2008 by Pär Wenåker

I recently got the opportunity to do a spike on a RESTful web services interface and decided to use JAX-RS and the reference implementation Jersey to do the prototyping. The term REST was coined by Roy Fielding in his Ph.D. dissertation back in 2000. There is lot’s of material on the web regarding REST and [...]

Integrating e-id with WebSphere Portal

April 17th, 2008 by Sofia Jonsson

I’m currently working on a project where we, despite its many drawbacks, have decided to use the “BankId” solution to authenticate our users. But this is not the whole truth; since not all Swedish banks have agreed on using BankId we have to use three different solutions in order to cover (most) users: BankId, Nordea [...]
