    How to use java.util.ServiceLoader inside an ear

    Robert Panzer Newbie

      Hi,

       

      I am trying to use the java.util.ServiceLoader inside an ear, i.e. I have an application like this:

      My.ear:

      +-lib

           +- A.jar

           +-B.jar

                +- META-INF/services/com.xyz.MyInterface

       

      Now a class that is in A.jar tries to get an implementation using

      ServiceLoader.load(MyInterface.class) and alternatively ServiceLoader.load(MyInterface.class, Thread.currentThread().getContectClassLoader()).

      But unfortunately both calls fail and return an empty iterator.

       

      In a test without a server it works fine, but as soon as I start this stuff on JBoss it fails.

       

      Has anyone already managed to get something like this running?

       

      I could imagine, that the jboss-modules refuses loading the services resources, but it should be possible to access it specifying some dependencies like for instance when you want to get th service of a module where you set Dependencies: MyModule service

       

      Does anyone have a good tip?

       

      Thanks & kind regards,

      Robert
