Short talk: OSGi Release Versioning Strategies

Industry standard release numbering schemes like {1.0-rc1,1.0-rc2, 1.0} or {1.0-SNAPSHOT, 1.0} don't work well for OSGi package versioning. This is because the lexical ordering on which they rely leads to situations where, for example, '1.0-rc1' is seen as a later version than '1.0-final', and is thus preferred if both are in the range specified by an importer. This talk explores various OSGi-friendly release versioning strategies, including use of attributes to identify release types like SNAPSHOTs.

Dave Savage of Paremus will present this talk at the Spring UK User Group meeting in London on 10th December .

Using Spring with OSGi is a revolution in the application server environment. Spring gives you flexibility, OSGi gives you dynamicity, but complexity can give you a headache! This talk will review the current technology landscape, explore how you can turn a standalone app in to a resilient, distributed system while taming the complexity and highlight the benefits and gotchas that you should consider when moving to this style of architecture.

EclipseCon is the premier technical and user conference focusing on the power of the Eclipse platform. From implementers to users, and everyone in between, if you are using, building, or considering Eclipse, EclipseCon is the conference you need to attend. Also, the OSGi™ Alliance has teamed up with EclipseCon to organize the 2008 OSGi developer conference, which will be the premier conference for OSGi developers to attend in 2008. Paremus will be in the exhibition area as well as presenting the following talks - which are now available to view and download:

Long talk: How To Build Large Scale Enterprise Applications Using OSGi

OSGi started out as a technology for building software for embedded devices, but it's applicability goes far wider than this as demonstrated by the activities in the OSGi Expert Enterprise Group over the past 18 months. This talk will review some of the challenges and benefits of taking OSGi out of the device, off the desktop and into enterprise scale deployments. There will be a review of the problem domain; discussion of applicable patterns; and references to a real world implementation. The talk will be technical in nature with code samples, and attendees should ideally have a basic understanding of OSGi.

Short talk: How to distribute Spring Dynamic Modules for OSGi

The Spring Framework has adopted OSGi for its component architecture. This talk will discuss how using the Newton open source distributed OSGi framework it is possible to transparently distribute Spring-OSGi based applications. A review of the basics of the Newton Project will be provided along with examples of how a Spring application developed on a single machine can be simply scaled out across a distributed environment. The session will also explain how Newton not only provides scale out but adds other benefits including automated deployment, dynamic resilience and simplified administration using a document driven approach.

Short talk: An Introduction to the Newton Project - distributed OSGi & SCA

The Newton Project is an open source framework, built upon OSGi and SCA standards, that provides a lightweight, distributed framework for next generation composite applications built out of OSGi bundles and described as SCA documents. In addition to distribution, Newton also provides a simple automated deployment model for application code and middleware, along with a sophisticated provisioning capability for ensuring application availability even under failure scenarios.

BoF: Distributed Computing with OSGi

OSGi's service oriented view is a natural fit with distributed computing. Whether you're interested in Newton, R-OSGi, Jini (Apache River) or home grown solutions to adding remote services capabilities to OSGi, drop by this BoF and share your thoughts and experiences. Paremus CEO Richard Nicholson will share this panel session with representatives of LinkedIn and ETH Zurich.

The Java Web User Group is an official recognised Java User Group. The JAVAWUG is a group of like-minded people who are interested in web and enterprise technology to do with the Java platform - primarily Java Enterprise Edition and Java Web technologies.

Paremus will be presenting a session entitled: "OSGi™ In The Enterprise".

Øredev is an independent conference that mixes open source with proprietary software, Java with .Net, small companies with multi-national companies, agile as well as pragmatic ones, but with one thing in common: they are all very experienced. There are seven parallel tracks at Øredev 2007 - Java, .NET, Methods & Tools, Test, Embedded System, Project Management and Architecture - and this year there is a special program for IT Business Managers in the parallel conference Øredev Extended.
