Thank you for your reply Vaclav,

Well, what you talk about was not the original problem but it is now the problem where I am stuck at :)

My architecture is about a generic HandlerService and ContainerService abstractions that are meant for handling HTTP requests asynchronously (with custom Request/Response abstractions). The idea is that ContainerService instances (based on Jetty, Tomcat, ...) should be able to pick up and delegate to HandlerService instances. This should work inside an OSGI container when deployed as bundles but I also want to be able to hard-wire them into a monolithic application.

I am embedding Jetty inside a bundle that should implement a ContainerService and it does indeed not find the its own ALPNProvider through ServiceLoader. I looked into SpiFly but it all seems a bit backwards to me when comparing it to my situation. I am not exposing anything Jetty/WebApp/Servlet from the bundle, it is purely an internal implementation detail of said bundle. Neither do I intend to do anything accross bundles with ALPN or any other ServiceLoader. I would prefer to hardwire Jetty to its own ALPN provider. Going through all kinds of hoops to get the ServiceLoader working at the OSGI level sounds all wrong. But if that is what it takes I will have to do it.

Unfortunately I can not get the SpiFly setup working. Could you tell me a bit more? Do you deploy SpiFly as an OSGI bundle on its own or do you embed it inside the same bundle that embeds Jetty? Are you using the dynamic SpiFly mode? What Jetty version are you embedding?

Any pointers would be very much appreciated.

Kind regards,

Silvio

I am not sure if I understand your issue in the entirety but here is something:

Are you embedding the entire Jetty JARs into your own OSGi bundle? I am doing this and I had an issue where the ServiceLoader services were not being registered with OSGi and were not being provided/wired into ServiceLoader.load() calls. In the end, I had to add all the Require-Capability and Provide-Capability into my own OSGi bundle's META-INF/MANIFEST.MF. This is a snippet from the pom.xml:

<Require-Capability>

</Provide-Capability>

This requires use of Apache SPI-Fly.

    have registered on the BundleContext. The bundle does not instantiate
    anything Jetty related yet (well, it did but I removed all code
    that did
    anything with Jetty), only the dependencies are in the POM and
    they are
    embedded in the bundle with
    <Embed-Dependency>*;scope=compile|runtime</Embed-Dependency> which
    causes the Jetty jars to appear inside the packaged bundle.

    When I remove the <Embed-Dependency/> the ServiceEvents occur as
    expected. But I need the Jetty dependencies in the bundle.

    Any ideas?

    Kind regards,

    Silvio
