Tomcat based implementation of OSGI HTTP Service [message #108391]

Hi,

did somebody know whether there is a Tomcat based implementation of the OSGi
HTTP Service?

Thanks,

George

You can use the servletbridge "with" Tomcat to get an Http Service based on
tomcat's infrastructure.
I'm not aware of a standalone Tomcat-based implementation. It wouldn't be
too hard to do though if the various pieces of Tomcat were available as
bundles. If you're looking to try take a look at
org.eclipse.equinox.http.jetty as the integration should be very similar.

Hi Simon,

thanks for your response.

Did you have a idea how much time it could take to develop such a bundle?
(to develop a full featured HTTP Service replacement)

We would be willing to create such bundles... (it would be just one of many
that will be in EILF). Would your team be interested in? Or could your team
give us some hints where we have to look at? [We are new on the topic OSGi]

From my point of view Tomcat is really flexible container and its well
proven at our customers. Did you think Jetty could be a good replacement?

Kind Regards,

Georg

You should check the Spring implementation. I came across this doc here and

Hard to say, but I was able to do the original Jetty integration very
quickly (> 1 day). The code in org.eclipse.equinox.http.jetty has improved
incrementally, but getting the basics up and running should still be pretty
easy. At the very least I'd suggest that determining how hard it might be is
a small job.

Great. Sure. The next few weeks are insane for us but after that...

Both engines are solid and used in a wide range of commercial environments.
Jetty is lean and particularly good for embedding. It's used as the
underlying servlet engine in a number of JEE servers. In addition the main
developers have been helpful to the OSGi work here so...

That said you're not the first to ask about a Tomcat implementation so this
sort of work would be useful.

Sorry... one question I forgot.

Which technology do you suggest as base.

Services, Declarative Services or Extension Points.

The spring web support in Spring DM is not an Http Service implementation.
But it may suit your needs if you have a web app(war) you want to deploy
into tomcat. And M2 has added Spring Web MVC integration/support.
