Enterprise OSGi uptake tops EclipseCon

OSGi took center stage at EclipseCon yesterday as conference attendees heard talks explaining why they should use this open-source application framework, even while others groused that the application model delineated by OSGi was too complex to implement yet.

The OSGi Alliance and the Eclipse Foundation have spent a lot of time and effort evangelizing the OSGi application framework, but even Eclipse Foundation director Mike Milinkovich admitted that enterprise users aren't quite up to speed on the technology. “For enterprise application developers, just giving them the bare-bones OSGi programming model and saying 'Good luck with that' is not the solution," he said.

While OSGi use remains strong for developers building on top of Eclipse and for vendors, uptake has been slow inside enterprises, said Jason van Zyl, creator of Apache Maven and founder of Sonatype, which sells OSGi bundle-making tools. OSGi is a set of specifications that define a component system for Java.

One of the reasons for that lack of uptake is that the OSGi development model is quite complicated, said van Zyl. For non-Eclipse projects, building an application that adheres to OSGi design principles is difficult, he added. Another issue, according to him, has been a lack of tools for building and dealing with OSGi-deployable artifacts.

Another company, Paremus, has built an OSGi shell that functions in a manner similar to Red Hat's yum and Debian's apt-get. The tool pulls down all the OSGi bundles needed to make a specific project run, and then properly installs them.

Another reason for slow OSGi adoption has been the lack of reference implementations for enterprise users. The Eclipse Foundation announced the release of two new projects aimed at offering enterprise users a view of how to build with OSGi: Eclipse Virgo and Eclipse Gemini.

Eclipse Virgo, formerly the application server known as DM Server, was created by SpringSource. Virgo gives developers a version of Eclipse designed specifically to function as a runtime environment for enterprise applications, and it allows developers to bring existing Spring applications into an OSGi-based environment with little recoding required.
