Hi,
I am trying to realize the following scenario:
1. Have one bundle (WC) initialize a web context (/app) via Pax
WebContainer and bind CXFNonSpringServlet to it (/app/services).
2. Allow other bundles (A, B, ...) to add endpoints and resources to
this web context. CXF endpoints should not be added to /cxf and
/app/services should not include ones from /cxf.
All configuration should be achievable from blueprint.
The last restriction of the second point is causing problems.
I have managed to register the CXFNonSpringServlet in WC. In order to
meet the restrictions figured out that I must provide a new
DestinationRegistry to the servlet. I'm doing this via the bus by adding
a custom feature to it:
<cxf:bus id="hicBus" bus="hicBus" name="hicBus">
<cxf:features>
<cxf:logging />
<ref component-id="hicRegistryFeature" />
</cxf:features>
</cxf:bus>
<!-- Bind a new CXFServlet to created bus -->
<bean id="hicCXFServlet"
class="org.apache.cxf.transport.servlet.CXFNonSpringServlet">
<property name="bus" ref="hicBus" />
</bean>
The feature uses a trivial implementation:
@Override
public void initialize(Bus bus) {
DestinationRegistry reg = new DestinationRegistryImpl();
new HTTPTransportFactory(bus, reg);
}
In bundles which contribute to that context I am looking up the CXF bus
and use it in the jaxrs server configuration:
<!-- Get the bus for this context -->
<reference id="bus" interface="org.apache.cxf.Bus"
availability="mandatory" filter="cxf.bus.id=hicBus" />
<bean id="service" class="..." />
<jaxrs:server bus="bus" id="server" address="/a">
<jaxrs:serviceBeans>
<ref component-id="service" />
</jaxrs:serviceBeans>
</jaxrs:server>
When I start my bundles everything works as expected. The servlet at
/cxf is not showing any endpoint registrations. The services at /app/a
and /app/b are accessible.
But when I stop one of the bundles, its registered endpoints do not get
removed from the registry (it's still showing up at /app/services) and
every query to any endpoint at /apps/* leads to an internal server error:
org.osgi.service.blueprint.container.ServiceUnavailableException: The
Blueprint container is being or has been destroyed:

Am I missing something in my configuration? Or is there any simpler way
to achieve my goals?
Any help is greatly appreciated.
