I guess the question is quite simple: how do you get a servlet component
registered using DS pick up a HttpContext? In vanilla OSGi, I can do this
quite simply in code, and using the whiteboard, I can do the same thing
programatically, but how does this work using DS?
Thanks

Sorry, that was my error. In fact this does have an exposed interface for
Servlet (see below). The problem seems to be that (either) DS or
whiteboard don’t match the contextId required by the servlet with the
contentId property declared by the component that provides it. As soon as
the servlet has the property contentId set, then it no longer is
accessible (felix http generates a 404).
Any ideas?
Thanks

I think you may need to have TestServlet expose an interface for
httpservice to find on the whiteboard, probably Servlet or HttpServlet.
With your xml as shown, TestServlet does not register as a service at
all.

From the component descriptors I see that you are mixing two approaches
1. TestServlet is obtaining a reference to HttpService and HttpContext
2. TestServlet is being registered with properties required by
whiteboard i.e. alias and contextId
Are you using httpService to programatically register the servlet? If
you just rely on whiteboard support then you need not use HttpService
or access HttpContext from within servlet. Instead you just need to
register your services with required properties i.e. alias and
contextId for Servlet and contextId for HttpContext and whiteboard
support would do the job of registering the servlet with proper
context

Hi All
Does anyone use the Felix http service, DS and the whiteboard with a
custom HttpContext?
I can register a servlet with DS and the whiteboard, but it doesn¹t
appear
to hook into my custom HttpContext. I have the component.xml below for
both the servlet and the HttpContext. Any pointers would be helpful.
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
name="TestServlet">
<implementation class="com.myriadgroup.httptest.TestServlet"/>
<reference bind="setHttp" cardinality="1..1"

policy="dynamic"
unbind="unsetHttp"/>
<reference cardinality="1..1"
interface="org.osgi.service.log.LogService" name="LOG"
policy="static"/>
<property name="alias" type="String" value="/test"/>
<property name="contextId" type="String" value="foobar"/>
<reference cardinality="1..1"
interface="org.osgi.service.http.HttpContext" name="HttpContext"
policy="dynamic"/>
</scr:component>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0";
