OSGi R7 early spec drafts available

Recently OSGi published the first early draft for the OSGi R7. While not all specs aimed for R7 are present yet, a few new ones have appeared that can be checked out. The new ones are:
  • Chapter 147 - Transaction Control Service. This specification provides an improved mechanism to perform work in a transaction scope. It provides a higher level of abstraction than the extising JTA integration specification, which makes it really easy to write transactional code, especially when using Java 8 lambdas.
  • Chapter 148 - Converter. Convert anything into everything, and back. A universal object converter which can be used to convert simple values between datatypes, but it can also be used to convert complex structures such as maps or DTOs to interfaces or annotations. Previously functionality such as this was already supported in DS, which allows you to access a component's configuration map via an annotation. Now, this can be used anywhere you like...
  • Chapter 706 - Push Streams. These provide a programming model similar to Java 8 pull-based streams, but then using a push model. Useful for data such as events that arrives asynchronously. The data can be mapped, buffered, splitted, filtered or otherwise processed before it gets sent to the receiver. 
You can find the R7 early drafts at the OSGi website here:
Opensource implementations are already starting to appear, check for where to obtain OSGi specification implementations.

As always, these are early drafts. Things will definitely change in some of the details. If you want to learn more about these and other upcoming OSGi specifications, come and visit the OSGi Community Event at EclipseCon Europe in Ludwigsburg

InfoQ: A comparison of OSGi and the Java 9 Java Platform Module System

In Java 9, OSGi and the Future of Modularity, Neil Bartlett and Kai Hackbarth provide part 1 of an excellent comparison of OSGi modularity and the current state of Java 9's Java Platform Module System (JPMS) modularity.
One of the most common complaints about OSGi is that it can increase complexity for a developer. There is a grain of truth here, but people who make this complaint are mistaking the medicine for the disease.
Modularity is not a magic dust that can be sprinkled onto an application just before release. It is a discipline that must be followed throughout all phases of design and development. Developers who adopt OSGi early and apply modular thinking before writing a line of code realise enormous gains[...]
Project Jigsaw started with a goal of being simple, but the JPMS specification has increased enormously in complexity: the interplay of modules with class loaders; hierarchical layers and configurations; re-exporting requirements; weak modules; static requirements; qualified exports; dynamic exports; inherited readability across layers; multi-module JARs; automatic modules; unnamed modules… all these features have been added as the need for them became clear. A similar process happened in OSGi, just with a 16-year head start.
The article is well written and provides a clear understanding of the differences between OSGi and JPMS as it stands today. Looking forward to part 2.

Want to become an OSGi Developer Certified Professional?

The next OSGi Developer Certification - Professional exam is taking place on the afternoon of Monday Oct 24 in Ludwigsburg, Germany. That's the day before the OSGi Community Event 2016.

This is your opportunity to validate your knowledge and experience with OSGi technology and specifications.

You should have some practical experience of working with OSGi and a good understanding of the OSGi R5 specification topics, but don't worry we do provide an electronic copy of the R5 specification for you to use during the exam so you don't need to commit the spec to memory!

The exam is 3.5 hours and is made up of three sections:
  • Section 1 - written questions and answers, both multiple choice and open questions
  • Section 2 - a practical assignment with working deliverables developed and submitted for assessment
  • Section 3 - a practical troubleshooting assignment.
Please see for further details on exam topics, what you need to bring with you and other useful information.

Its US $500 per candidate sitting the exam. A special student discounted price of US $200 is available with proof of student status.

MODCONF 2016 - CFP Open Now

A new conference, MODCONF, is being held in November this year.  As you can hopefully
guess by the name its all about Modularity and software. Clearly this is very applicable to OSGi so when the OSGi Alliance was invited to support the conference we were pleased to accept.

The first MODCONF will take place in Darmstadt, Germany on November 15, 2016.  The conference is being organised by Liferay but it will not be covering Liferay products. Co-located with the event is Liferay DevCon, which will cover their products.

The Call For Papers for the conference is open now and submissions from anyone in the OSGi Community are encouraged and very welcome.  You can find full details of the type of talks that they are looking for and how to submit a talk online here. Of course be sure to have a punch Title and Abstract to submit.

Also please ensure you list your submission as a Modularity Conference Talk as the talk type when submitting.

You will probably note that the CFP deadline is officially Aug 12.  I do however have it on good authority that they will be pleased to receive OSGi related submissions up to the end of August.  Thats still not too much time, so the sooner you can submit the better,

For those of you who don't want to provide a talk but are interested in attending you can find full details on how to register here.

We hope you can help ensure OSGi is well represented in the conference program and help make this new conference a success.  Please contact the Marketing team at the OSGi Alliance or the MODCONF organisers if you have any questions.
