Bundle.update: OSGi in Java EE, JSR 294 Marked Inactive

by Alex Blewitt on  Dec 11, 2009 1

Since the last bundle.update, a number of interesting events have occurred in the OSGi and modular Java space. JSR 294 has been (automatically) marked as inactive, the Enterprise Expert Group has released draft 4, WebSphere will allow direct running of OSGi applications and upcoming OSGi conferences have early bird discounts and call for speakers finishing soon.

Bundle.update: the Current State of OSGi

It's been a month since OSGi 4.2 was released. What's been happening in the OSGi space since then?

Can the Simple Module System save JSR294?

by Alex Blewitt on  Aug 20, 2009 9

Over the past month there has been a lot of debate on the current state of the Java Modularity working group (JSR 294). Although the JSR tries to find common ground between different module systems (notably Sun's Project Jigsaw and OSGi), the current set of proposals are overly complex and introduce the world's first concept of a meta-module system. Can the Simple Module System save JSR294?

OSGi: The Next Release

by Alex Blewitt on  Jul 17, 2009 2

Peter Kriens, technical director of the OSGi alliance, gave a presentation on the upcoming OSGi 4.2 release at the UK OSGi Users Group. The event was recorded, and the video is now available. OSGi 4.2 is expected to be released to the public by the end of August 2009 and includes a number of new features.

Jigsaw - the death knell of JSR277?

by Alex Blewitt on  Dec 03, 2008

Following up from an earlier post about modularising the JDK (which InfoQ covered earlier), Mark Reinhold posted the announcement of Project Jigsaw as part of the OpenJDK. Is this the death of JSR277?

Are JSR277 and OSGi coming together?

by Alex Blewitt on  May 19, 2008

Last month we asked whether Sun were listening about OSGi; at JavaOne, it was clear that many others have. Not only are all of the main J2EE engines now OSGi-enabled, but Spring launched their OSGi-based Spring Source Application Platform. Fortunately, a number of positive changes have occurred behind the scenes with JSR277; read on for what's been happening.

Interview: Peter Kriens discusses OSGi

by Ryan Slobojan on  Sep 26, 2007 1

OSGi is a Java modular development specification. OSGi is used in a wide variety of applications, from mobile phones to enterprise servers and the Eclipse IDE. In this interview, Peter Kriens explains where OSGi came from, what sorts of applications it's useful for, integration with Spring, the JSR 277/294 debate, and the future of OSGi.

JSR 277 and JSR 291 Interoperability threatened by lack of a prototype

by Rob Thornton on  Sep 13, 2007 3

The latest salvo in the discussion of JSR 277, JSR 291, and OSGi appeared last week in the form of a post by Glyn Normington, spec lead for JSR 291 and Expert Group member for JSR 277. He is concerned that the Expert Group has not been presented with a strawman yet and that the Expert Group will end up merely rubber stamping the strawman rather than discussing it in detail and making changes.

Apache Geronimo 2.0: Certified Java EE 5 compatible

by Ryan Slobojan on  Aug 29, 2007 1

Apache Geronimo, an open-source Java Enterprise Edition (Java EE) application server, recently released version 2.0.1. InfoQ took the opportunity to learn more about Apache Geronimo and where it fits into the application server space.

Update on Java Modules

by Rob Thornton on  Mar 14, 2007 2

Glyn Normington has written an overview of Java modularity covering JSR 277, JSR 291 and JSR 294. He describes how each is different and adds value, and later responds to the question of why we need modularity support in the JVM, as opposed to custom classloaders (like OSGi).

JSR 291 (OSGi) passes Public Review ballot

by Rob Thornton on  Jan 23, 2007

JSR 291 (OSGi 4.1) has passed its Public Review ballot. There were two no votes, by Sun and Hani Suleiman, both arguing that that the expert group merely pointed to the OSGi spec, rather than working to define what was needed.
