I have been trying to get the sample.http.registry to function. I am using
Tomcat 5.5.17. The output of the ss on the console gives me the following:

Framework is launched.

When going to /ext/helloworld I receive the following error:

I have put the directory sample.http.registry within the
WEB-INF/platform/plugins/

Any help will be appreciated, or a guide on setting up the
sample.http.registry example.

I am also looking for any tutorials or references for using Equinox within
a servlet enviroment and working with current servlets I have.

Hi Ben,

It looks like you've configuration is fine.

I'm going to guess that it might be something wrong with the
sample.http.registry bundle itself.
I wonder if you created the bundle by repackaging the folder?
The zip contains the actual project and the paths are wrong if used as a
bundle. (e.g. the classes are in /bin)
You should still be able to access helloworld.html as coincidentally its in
the right place.

I've enclosed an exported bundle based on the project that I've just
verified works. (...it's just 2KB)

Hello,

I've been trying to use that sample, too. But when I load it to my
eclipse, or try to rebuild the structure for my own projects, eclipse
always tells me, that the extension-points
"org.eclipse.equinox.http.registry.servlets" and
"org.eclipse.equinox.http.registry.recources" are unknown.

Any idea what might be wrong (Eclipse 3.2 and the plugins from
eclipse-equinox-3.2.zip are installed).

Hi,

got it working - my fault: I simply forgot the incubator-bundles
(another new install of eclipse).
