Hey,
I'm trying to develop a custom HttpContext to provide security via the
handleSecurity() method.
The idea being someone wanting to protect their resources/servlets would
just need to specify this custom SecureHttpContext when registering the
servlet/resource.
The problem I'm having is trying to figure out how to implement
getResource() when the HttpContext and servlet/resource are configured
as extensions.
When a HttpContext is configured as an extension, and the 'CLASS'
attribute for the extension is specified, then the creation of the
HttpContext is done via a call to
IConfigurationElement.createExecutableExtension(CLASS), in
org.eclipse.equinox.http.registry.internal.HttpContextManage r.added(IExtension
extension). Which means that the custom HttpContext doesn't receive a
reference to the loading bundle, or any path that may have been set in
the extension details, as the DefaultHttpContextImpl does. So I can't
figure out how to load any resources that are supplied by the bundle.
At the moment I've modified HttpContextManager to use reflection and
call setBundle() and setPath() on the context it creates if it has these
methods, but after doing this I figured either I must be missing
something or that I'd like to submit an enhancement request.
Can anyone help?
Cheers,
Shaun

Hi Shaun,
If your custom HttpContext needs access to the config information in the
extension have it implement org.eclipse.core.runtime.IExecutableExtension or
better use an IExecutableExtensionFactory.
One slight pain is to then get the associated Bundle as (at least when I
last looked) the registry does not provide direct support for going from the
Contributor to the contributing Bundle. You can do it with PackageAdmin
however it's a bit of work as you can see in HttpContextManager.

Thanks Simon,
I knew there'd have to be a way to do it.
Obviously (now anyway) the IExecutableExtension was the way to got with
the path (30 seconds to fix that one).
And now I'll get my activator to track a package admin service and use
the contributor name in the setInitializationData() to find the bundle.
Too easy.
Cheers,
Shaun
