Easy REST endpoints with Apache Camel 2.14


Apache Camel has a new release recently, and some of the new features were blogged about by my colleague Claus Ibsen. You really should check out his blog entry and dig into more detail, but one of the features I was looking forward to trying was the new REST DSL. So what is this new DSL?

Validate Configuration on Startup


Do you remember that time when you spent a whole day trying to fix a problem, only to realize that you have mistyped a configuration setting? Yes. And it was not just one time. Avoiding that is not trivial, as not only you, but also the frameworks that you use should take care. But let me outline my suggestion. Always ...

Java Minor Releases Scheme Tweaked Again


In 2013, Oracle announced the Java SE – Change in Version Numbering Scheme.

As I got round to busy myself with this topic recently, I wrote a little helper with the intent to reduce boilerplate code for common programming steps, while increasing development guidance and readability at the same time. It turned out to be not that easy to find ...

A microservice is a small, focussed piece of software that can be developed, deployed and upgraded independently. Commonly, it exposes it functionality via a synchronous protocol such as HTTP/REST. That is my understanding of microservices, at least. There is no hard definition of what they are, but they currently seem to be the cool kid on the block, attracting increasing attention ...

Typesafe APIs for the browser


A new feature in Ceylon 1.1, that I’ve not blogged about before, is dynamic interfaces. This was something that Enrique and I worked on together with Corbin Uselton, one of our GSoC students. Ordinarily, when we interact with JavaScript objects, we do it from within a dynamic block, where Ceylon’s usual scrupulous typechecking is suppressed. The problem with this approach ...

Spring @Configuration – RabbitMQ connectivity

So this was my original configuration:             <beans ...;> <context:property-placeholder/> <rabbit:connection-factory id="rabbitConnectionFactory" username="${rabbit.user}" host="localhost" password="${rabbit.pass}" port="5672"/> <rabbit:template id="amqpTemplate" connection-factory="rabbitConnectionFactory" exchange="" ...
