Hi.
Please, can you address me about how I can get the
org.eclipse.equinox.http.servlet.jar for downloading for Equinox?
From the download page
( http://download.eclipse.org/eclipse/equinox/drops/S-3.5M1-20 0808071402/index.php
) I can only see
org.eclipse.equinox.servletbridge_1.0.100.v20080427-0830.jar .
Am I missing something?

Thanks in advance.
Kind regards.
Maurizio

Thanks Maurizio,

That's an older download page you're using and you instead should be using
http://download.eclipse.org/equinox/

There is still a typo on that page as you've identified so I'll log that and
get it fixed.

For now here's a direct link to 3.5RC4 version --
http://www.eclipse.org/downloads/download.php?file=/equinox/ drops/S-3.5RC4-200906051444/org.eclipse.equinox.http.servlet _1.0.200.v20090520-1800.jar

FWIW This file is also included in the Eclipse SDK -- that's probably the
easiest way to make use of it.

Dear Simon,
Thanks again for your reply.
I downloaded the JAR file from the URL that you indicated, and that's OK.

Dispite that I think I need some help while trying the "OSGi Web
application development with Server-Side Equinox", that I followed at
" http://www.javaworld.com/javaworld/jw-06-2008/jw-06-osgi3.ht ml?page=1".
This article indicates the need of the following bundles:
javax.servlet v2_4
org.apache.commons.logging v1_0_4
org.eclipse.equinox.http.jetty
org.eclipse.equinox.http.registry
org.eclipse.equinox.http.servlet
org.mortbay.jetty v5_1_11
I have installed all of them in my Equinox container, where I'm using
"org.eclipse.osgi_3.5.0.v20090520.jar".
This is what I can see from the Equinox console:
osgi> ss

Framework is launched.

id State Bundle
0 ACTIVE org.eclipse.osgi_3.5.0.v20090520

16 INSTALLED org.eclipse.equinox.http.jetty_2.0.0.v20080425

osgi>

Until here, I don't see problems.

What the article tells now is "verify that you can access the Jetty server
by pointing your browser to http://localhost/".
At this point I would imagine that I should start the Jetty server from
the console, but if I type "start 13" I just get back the "osgi>" prompt
without any message from the Jetty server and, more important, when I try
to activate the browser at "http://localhost/" I cannot see anything like:
HTTP ERROR: 404
ProxyServlet: /
RequestURI=/
Powered by Jetty://

So, I would conclude that the Jetty server is not active, at all.

So the questions are:
1. Should I just start Jetty (bundle 13) or I should start some of the
other bundle manually first?
2. If it is so, which is the order, if it is important?

If this is not the proper root to follow, please can you address me
through some further explanation about "Web application development with
Server-Side Equinox"?

Thanks very much.
Kind regards.
Maurizio

Be careful: This article is based on Eclipse 3.4.x, which is using Jetty
5.1.x.
Eclipse 3.5.x is now based on Jetty 6 which requires different bundles.

I would recommend to use latest Equinox SDK 3.5 build, probably as a
separate target platform, or use Eclipse 3.5 with self hosted target
platform.

The most simple way to setup a launch configuraton is: select
"org.eclipse.equiox.http.jetty_2.0.0....." and then click "all required
bundles". Validate plugins, and everything should work.

Background: the o.e.e.htpp.jetty_2.0.0 is the HTTP adaptor for Jetty 6.x.

The OSGi bundle which starts the OSGi HtpService is not the Jetty
bundle, use instead again the "o.e.e.http.jetty_2.0.0..." adaptor bundle.

See above

Ordering is not important, as all required bundles (jetty, jetty.util)
only needs to be installed and resolved, but not started.

We gave a tutorial at EclipseCon 2009 about building web applications
with OSGi and Equinox. See presentation at

Dear Jochen,
Thanks for your indication.

I'm currently using plain Equinox-SDK-3.5RC3, without Eclipse, and I
didn't realize that the examples were based on V3.4x.
Question: may I assume that Eclipse versions and Equinox version should
match, i.e. your statement indicates that Equinox V3.5 is based on Jetty 6?
Can I use plain Equinox or I should change using Eclipse over it?

You say "... select "org.eclipse.equiox.http.jetty_2.0.0....." and then
click "all required bundles". Validate plugins, and everything should
work".
Question: I downloaded org.eclipse.equinox.http.jetty_2.0.0.v20080425.jar
from "http://download.eclipse.org/equinox/" and I couldn't see any option
like "all required bundles" to click. Please, can you explain from which
environment I should do that?

In the meantime I downloaded the PPT of the tutorial at EclipseCon 2009
and I'm looking at it. I wonder if and how I can access the exercises of
such tutorial. They look like my needed starting point.

I would like to have your comments.
Thanks in advance.
Maurizio

Hello Jochen,

I'm having exactly the same problems embedding jetty in my
plugin/feature. The trick is to get the http service started. It seems
to come up automatically when adding -Dorg.osgi.service.http.port=xyz to
the command line.

I've also tried programmatic approaches (e35) but not a single one
worked reliably.

I believe except for the version number the bundles are still the same.

Not sure what you're saying here. If I'm trying bundle.start() do I need
to start org.eclipse.equinox.http or org.eclipse.equinox.http.jetty? How
can I make sure that also the servlet bridge and the registry come up-
do I need to ensure manual startup of all these bundles?

If I want to check if the http service is up, or attach a
ServiceListener to it, what do I need to check for using
context.getServiceReference()- against org.eclipse.equinox.http,
org.eclipse.equinox.http.jetty or really org.osgi.service.http.HttpService?

Took a look, but honestly not too helpful if you're not
OSGi-knowledgable already, sorry (no offence meant).

I'd be happy though- once I get this sorted out- to provide a writeup of
my experiences for http://www.eclipse.org/equinox/server/http_in_equinox.php

Best regards,
Andreas

another thought on the plugins- which ones would I really need to
require and which ones to import?

Looking at the org.eclipse.equinox.http.registry's plugin.xml e.g. seems
to indicate that I might which to only import these:

javax.servlet
org.osgi.service.http
org.osgi.util.tracker

Best regards,
Andreas
