Living Software - Instil’s Team Blog

We are helping organise a Java DevDays (http://devdays.info) event in Belfast and are looking for speakers and topics.   We’ll definitely be covering Java server side development, but one suggestion is to extend things to cover Android, Scala and perhaps even Flex (not Java of course, but very Java-esque).

A date for this event is yet to be announced, but if you would like to get your vote in early for things you would like to see covered, do let us know.  And spread the word.

Instil will be talking about our experiences with OSGi at the next UK OSGi User’s Group meeting in October.

Title of Presentation
OSGi in Anger

Brief Synopsis
Telecom Web Services is an application framework that enables the creation of SOAP and RESTful applications over telecom capabilities such as SMS, MMS, Location, etc.

Starting off life as a single monolithic project, the system has evolved into a highly modular product made up of many OSGi bundles and a design that relies heavily on OSGi services to support core infrastructure and to enable OCP-style extensibility.

With 10000+ unit tests, TWS is a fairly large and complex system, but thanks mostly to OSGi it has managed to maintain its design integrity and yet remain relatively cheap and easy to work with and extend.

However, developing with OSGi has not been without its own share of pain, and in this talk Tara will discuss how these issues were overcome as well as how its many great features were put to effective use, and how they helped solve many problems:

• The virtues of enforced modularity (on a large project)
• Working with OSGi services and how services were used to underpin many design decisions
• Wiring & Spring DM
• Working through the pain barrier - Hibernate, build, perceptions of complexity,…
• Testing
• Lessons learned

We have joined the great unwashed and are twittering away about software and life. You can follow Tara at http://twitter.com/TaraSimpson and Marty at http://twitter.com/henderson_mk.
