Building Your Equinox OSGi Application Server – Part 3

p37

In part 2 of this blog series, I described how to use Equinox p2 to install a new feature into a running Equinox application server. Rather than do this install at runtime via the OSGi console, many times it’s desirable to add bundles to an application server statically at build time rather than at runtime.  For [...]

Over the past year I’ve developed a goal of making it easier to build and deploy the Equinox runtime as a web application server.  Not only does this fit my technical skills having previously worked on a commercial application server, it also fits my technical interests.

Early bird defines the worm!

In his posting All contributions are Equal, some are more equal than others, Robert Konigsberg points out that contributing multiple ways of doing things can easily lead to more user complexity (e.g., by having multiple toString generators). This is true and in my view, a risk for any system that has many strongly-opinioned contributors (pretty [...]

Portland Galileo DemoCamp – ECF slides

As Elias and Darin already blogged, there was a memorable DemoCamp session in Portland Wednesday night.  Thanks to Instantiations for organizing and hosting. The ECF slides for this are here.  Some of them I didn’t actually have time to show at the DemoCamp, so there’s a little new information there, even for those that were [...]
