  • Deep testing of integrations with Camel

    One of the things that often comes up in client conversations about developing integration code with Camel is what test support is available, and more to the point appropriate, for testing integrations. There is a spectrum of test types that can be performed, ranging from fully automated unit tests to full-blown multi-system, user-based “click and…

  • Transactional persistence with MyBatis in ServiceMix

    This post has been a long time coming. A while back I cooked up a sample application, kind of a pet store for integration, that demonstrates a bunch of things that you might want to do beyond the standard bootstrap examples. This app takes the form of a horoscope aggregator, which allows you to view…

  • System Integrations as Plugins using Camel and ServiceMix

    I recently had a client with a use case that I thought would be interesting to share (and they were happy for me to talk about – no names, industry changed). Sample code and full instructions for the solution available as always at FuseByExample on Github. Imagine a system integration where the core logic is…

  • Machiavelli on software

    It must be remembered that there is nothing more difficult to plan, more doubtful of success, nor more dangerous to manage than the creation of a new system. For the initiator has the enmity of all who would profit by the preservation of the old institutions and merely lukewarm defenders in those who would gain…

  • IT side-effects at the NHS

    My mother has a a phrase – professional illness. It’s the moment that she (an environmental engineer) walks into a random building and promptly looks at the air ducts. I suffer from the same thing – only around tech. Before and after the birth of my daughter, I have had more chances than ever to…

  • Developing web services in ServiceMix

    I have added a number of projects to FuseByExample/smx-ws-examples on GitHub that demonstrate how to go about developing a number of common web service use cases. The samples are designed to get you up and running quickly with SOAP based web services in an OSGi world. The examples include: a Maven project that generates all…

  • Build-time integration testing OSGi bundles in ServiceMix

    I have just added a new project to GitHub under FuseByExample/smx-integration-testing that you can use to verify at build time that your bundles and features will deploy and run as expected in a specific version of ServiceMix. The intention is that you can use it to kick start testing in your own projects. To do…

  • Bootstrap Projects for Getting Started with ServiceMix 4

    Over the Christmas break I cleaned up and published a set of Maven projects for getting started with ServiceMix 4.4.1+ into GitHub. I found myself reusing the same code for a number of activities, and figured it may be of broader use to others. You can find it under FuseByExample/smx-bootstraps. smx-bootstraps contains within it a…

  • Understanding ActiveMQ Broker Networks

    Networks of message brokers in ActiveMQ work quite differently to more familiar models such as that of physical networks. They are not any harder to understand or reason about but we need to have an appreciation as to what exactly each of the pieces in the puzzle do by themselves in order to understand them…
