OSGi and Java 9+ (BJ Hargrave, IBM) 
Abstract: 
Java 9 introduced the Java Platform Module System (JPMS) as a way to modularize the Java platform and it can be also be used by developers to modularize their own applications, although JPMS lack a number of important features for software running on the Java platform.

As people look to support the latest versions of the Java platform, changes introduced in Java 9 related to JPMS led to the needs for some features in the OSGi Core specification. OSGi framework implementations like Eclipse Equinox and Apache Felix and tools like Bnd were updated to support these new features.

Bio: 
BJ Hargrave is CTO of the OSGi Alliance and chair of the OSGi Core Platform Expert Group.  His day job is as Senior Technical Staff Member in the IBM Digital Business Group. BJ has led the development of OSGi technology since its inception and is a committer on the Eclipse Equinox project and the Bndtools project.

Fit for the Edge: Making OSGi Robuster and Realtime Capable (Dr James Hunt, aicas)
Abstract: 
OSGi brings many benefits, but it lacks two important features for Industry 4.0: strong bundle isolation and the ability to provide realtime guarantees.  The Realtime Specification for Java 2.0 provides
the basis for filling this gap.  It provides both APIs and JVM semantic refinements for realtime programming and resource management.  Marrying these features to OSGi will make OSGi the leading platform for edge computing.

Bio:
Dr. James J. Hunt is CEO and cofounder of aicas GmbH, the leading provider of realtime Java technology for embedded system.  Educated at Yale, Boston University, and the University of Karlsruhe, he has worked in diverse projects such as restructurable wafer scale integrated circuits (RVLSI), parallel Lisp, software standards, and realtime Java. He is the specification lead for the Real-Time Specification for Java (JSR-282). He was also European Cochair for the subgroup on object-oriented technology of the SC-205 Plenary for updating software safety standard for avionics, resulting in the Object Oriented and
Related Technology Supplement now published as DO-332 and ED-217.  He joined the OSGi Alliance to bring realtime to OSGi.

Popular patterns revisited on OSGi (Christian Schneider, Adobe)
Abstract:
We will look at common cloud and design patterns and see how the special properties of the OSGi environment allow us to rethink these patterns. The talk shows some well-known patterns like the service registry and the whiteboard but also some unique patterns like out of band circuit breaker or graceful degregation. The patterns are shown with some examples using declarative services(DS). So some basic OSGi and DS knowledge is of advantage but not required.

For OSGi beginners, the well established OSGi patterns will help getting started the right way. Experienced OSGi developers will find some new patterns to think about. Cloud or enterprise developers will get a new approach to some patterns they are used to which hopefully inspires them to take another look at the current state of OSGi.


Bio:
Christian is a computer scientist working at Adobe on the Adobe Experience Manager Platform team. On the open source side he is involved with quite a few Apache open source projects like Felix, Karaf, CXF, Camel. Christian is interested in clean code, software architecture and modular software design.

We hope you can join us in Berlin next month.  If you have any questions please contact us by email.

OSGi Community Event 2018 - Slides & Videos Now Available



Click here for OSGi Community Event 2018 Slides and Videos



So the OSGi Community Event 2018 has come and go again for another year.  Thanks to everyone
who joined us and also to the speakers who provided the talks (and lots of pre-event hard work preparing them) that are essential to the success of the conference.

This year we learnt how OSGi is being used by ESA for tracking and controlling spacecraft, we discovered how virtual reality can be used to understand the dependencies within OSGi software, we had an insight on using Node-RED with OSGi, and we also learnt how OSGi is being used to build Open Liberty and the benefits that it brings to a large codebase like this.

BJ Hargrave, OSGi Alliance CTO also provided an overview of what has been added to OSGi R7 and Bnd to help navigate Java 9+ and JPMS.  There were also several looks in to the future of how OSGi can be used with Docker and Kubernetes and how OSGi fits with MicroProfile.

Thanks also to our hosts, EclipseCon Europe, who we were pleased to co-locate with again this year in Ludwigsburg.  The social events and networking opportunities were in abundance again and appeared to be thoroughly enjoyed by the OSGi and Eclipse communities.

The slides and videos from the talks at this years event are now available and you can find these by reviewing the 2018 schedule on our conference web page.

The final word of thanks goes to our 2018 OSGi Community Event Sponsors, whose support helps ensure the conference can take place.  This year Bosch and IBM were Dual Elite (OSGi and EclipseCon) sponsors and Liferay was an OSGi Conference sponsor.

Countdown to OSGi Community Event 2018

So it's reaching that time of year again. Not only is it, gulp, only 91 days to the end of the year and a mere, double gulp, 84 sleeps until Christmas, October is a really big month in the OSGi schedule.

Today, being October 1, means we are just 22 sleeps until OSGi Community Event 2018.

We have a packed schedule again this year in Ludwigsburg, Oct 23 to 25, including:
And if all that OSGi goodness isn't enough, we are co-located with EclipseCon Europe again this year and attendees get full access to the EclipseCon schedule and exhibition, along with all the excellent social events.

Registration is still open, so if you haven't booked your ticket yet I encourage you to do so fast and to secure your hotel as rooms are selling out.

Big thanks go to the following companies who have sponsored the OSGi Community Event in 2018. It is their support that makes it possible for us to bring this event to you.


See you in Ludwigsburg soon.

Meet us at Liferay DEVCON

The OSGi Alliance is pleased to be attending Liferay DEVCON in Amsterdam in November.  The main conference is taking place November 7 and 8 and we will have an OSGi booth in the exhibition area.  There is also an unconference taking place the day before the main conference on November 6.


We are happy to answer any questions you have about modularity and OSGi technology, the OSGi Alliance, the new R7 release and anything else you can think of that is OSGi related.

We would also encourage anyone who might be interested in joining the OSGi Alliance and contributing to the ongoing evolution and development of the open standard OSGi specifications to come and chat with us at our booth.  Even though R7 is only just out the door, we are already drawing up ideas for Release 8 (R8) and so now is a great time to join us and get involved in the new activities.

Liferay is an extensive user of OSGi technology and we are really pleased to have the opportunity to meet their community of users and developers at this key event.  Ray Augé, a Senior Software Architect at Liferay, and co-chair of the OSGi Enterprise Expert Group, will be presenting on the upcoming OSGi CDI integration specification. Ray's talk will demonstrate common usage patterns and its component model that brings OSGi dynamics; like services and configuration, to CDI and provides for an ecosystem of CDI portable extensions.

You can find out more about this year's Liferay DEVCON including how to register on the conference website.

We realize that this is coming hot on the heels of the OSGi Community Event and EclipseCon Europe in October and Liferay is offering a 25% discount on DEVCON ticket prices to anyone that is attending that event this year too.  To obtain your discount code please see the Liferay advert in the OSGi Community Event and EclipseCon Europe event brochure.

OSGi R7 Highlights Blog Series

The OSGi R7 Highlights blog series has come to a close and we certainly want to thank you for following the series and hope you found it insightful and useful!  The series featured posts from technical experts at the OSGi Alliance sharing some of the key highlights of the new R7 release.

Its worth noting that the OSGi Core specification has provided a stable platform for developing modular Java applications for almost two decades. The OSGi Core R7 specification continues this tradition by providing updates to the OSGi Core specification which are fully compatible with previous versions of the OSGi Core specification.  This gives developers and users of OSGi technology an established track record of certainty of their investment protection from adopting OSGi.

The blog posts covered the topics below so if you missed reading any of the posts, be sure to take a moment to check them out.

Feel free to send questions regarding any of the OSGi R7 blog posts to us by email or as comments on the post in question.  We welcome any and all feedback and want to hear from you if you have any suggestions on future topics related to OSGi R7 or otherwise.
