Eclipse Announces New Runtime Initiative Around Equinox

The Eclipse Foundation this week unveiled a new initiative for developing and promoting a community around Equinox, the lightweight OSGi-based runtime. The initiative combines a new top-level Eclipse project that pulls together different threads within the Eclipse community around runtimes with a newly launched community portal.
"We sort of hit critical mass," said Mike Milinkovich, executive director of the Eclipse Foundation. "It became painfully obvious that we needed to provide a center of gravity for all of this work."
Equinox is the core runtime for the Eclipse framework. It's an implementation of the OSGi R4 core framework specification. OSGi (Open Services Gateway Initiative) defines an architecture for developing and deploying modular applications and libraries. It's used for mobile and embedded devices, desktop applications and server applications hosted on a range of operating systems.
Equinox lies at the heart of the Eclipse Runtime project (Eclipse RT), which aims to provide developers with something they're currently missing: a consistent component model that spans both tiers and platforms.
"If you look at .NET, you'll see a platform that crosses tiers, because there's a common component model across devices, desktops, and servers," Milinkovich said. "But the only platform they're interested in is Windows. If you look at the Java space, there's a great cross-platform story: It runs on Linux, Windows, Mac, and so on, but there isn't a great tier-spanning story, because they made the choice some years back that the component models for Java ME, SE, and EE would be different."
Eclipse RT introduces a concept called Component Oriented Development and Assembly (CODA). With a common component model that is used by both the application writers and the underlying platform, developers can not only to write their own components and pick and choose among them, but select which components or services from the underlying platform they want to bundle into their solutions.
"What you end up with is an architecture that is much more common and consistent through the application and runtime layers in the solutions you're building," Milinkovich said.
