Hey Alex. You’re quite right that server-based != servlet-based. However, strictly speaking, the title is totally correct; the entry talks about building *a* bundle-based server, and an HTTP server certainly qualifies…

[…] Eclipse runtime folks are beavering away on Equinox and server side focused tooling. Wayne has more details. I’m looking forward to trying this […]

Wayne,

You might want to re-title this as ‘web server’ rather than ’server’. After all, plenty of other servers exist in an OSGi environment other than those that speak HTTP. You might also want to touch base with Simon and mention the same thing - after all, server-side is a location, not a prescription.

Wayne/Patrick

If you are looking for OSGi server side clustering/resilience, scale out, etc you should take a look at the Newton project (www.codecauldron.org) and the commercial distributed OSGi runtime product called Infiniflow (www.paremus.com) which builds on top of Newton. There is transparent support for Spring Dynamic Modules too.

We will be at ElipseCon in the exhibition area and we have a couple of talks and are involved in a BOF.

Regards
Mike (Paremus)

Wassim, I could just as easily have been running Apache HTTP Server on Windows. Come to think of it, last time I had this sort of problem on Windows, the problem was that Windows didn’t seem to think it was a problem and let me reuse the port anyway. Hilarity ensued.

Patrick, the Jetty engine used by Eclipse is a real servlet engine that’s used in lots of different places. Likewise, there are a lot of people doing interesting server stuff with Equinox. I’ve only just started looking into this space, and I’m not aware of any specific clustering solutions that exist yet. OSGi server is still relatively young, so this is something that will likely develop with time. That said, not everybody needs clustering, HA, failover, etc. in their solutions. If you do, you probably still (at least today) want the weight and resources of a commercial entity and product behind you.

As I dig further into this, hopefully I will get some interesting stories to tell…

That’s fantastic to be able to leverage the servlet API from within a bundle. But what are the real life applications of an “OSGi server” outside serving local page to the help system?

Server side java has been around for a long time and we have come to expect scalability (eg clustering) and High Availability almost out of the box.

After being exposed to OSGi on the client side, I am really willing to take it to the server side, but without features such as clustering, I am going to have a hard time explaining to those ops guys why this new technology is so much better than [insert your favorite app server with clustering capability].

There is a solid operating system out of the state of Washington called Windows. You should try it.

thanks Wayne, looks exactly what I was talking about in http://dev.eclipse.org/newslists/news.eclipse.technology.eep/msg00010.html
can’t wait to see the article.

I wonder what are your thoughts on the rest of ideas posted in that email, too bad EEP went to review before taking discussion.
