Hi Thomas,
I think this fix is not correct. If the http service can only be found
with .open(true) it means that the package the service implements and
the package cxf imports are different.
I assume you simply forgot one step of the bridge installation guide:
http://felix.apache.org/documentation/subprojects/apache-felix-http-service.html#using-the-servlet-bridge
be sure to add |javax.servlet;javax.servlet.http;version=2.6| to OSGi
system packages (|org.osgi.framework.system.packages|);

Hi everyone,
I am having some problems with CXF HTTP Transport in an OSGi environment using
Apache Felix as OSGi Framwork.
I'm using the Felix Http Bridge to start Felix within a .war web application
which runs in Tomcat. The problem is, that the ServiceTracker which is set up
in org.apache.cxf.transport.http.osgi.HTTPTransportActivator does not find the
HttpService which is provided by the bundle org.apache.felix.http.bridge.
I tried a small change in the CXF code, changing line 64 in
HTTPTransportActivator to
httpServiceTracker.open(true);
With this change the HttpService is recognized by the ServiceTracker and the
CXF Servlet is setup correctly.
I did a bit more debugging to get to the root cause of this behavior and found,
that the problem is caused when the method
ServiceRegistrationImpl.isAssignableTo()
is called in the process of opening the ServiceTracker and getting the list of already available
services for the interface HttpService (ServiceTracker. getInitialReferences() ->
context.getServiceReferences). The Implementation of Felix' HttpService
(org.apache.felix.http.base.internal.service.HttpServiceImpl) implements not only HttpService but also
ExtHttpService. And when asking ServiceRegistrationImpl.isAssignableTo() with the parameters
requester: "org.apache.cxf.cxf-rt-transports-http [27]" and className:
"org.apache.felix.http.api.ExtHttpService" it returns false.
Now a simple fix is given by what I already wrote above: Changing
httpServiceTracker.open() to httpServiceTracker.open(true); in
HTTPTransportActivator
So I'd like to ask two questions:
1. Does anyone have a better solution on how to get this scenario working?
2. If not: Could this fix be inserted into the CXF code to enable us (and
others which might have similar problems) to use the offical .jar and not a
self-built one?
Thanks for your comments,
Thomas
