Hello Raymond and thank you,
yes we know exactly that it is used the
single argument ServiceLoader constructor and yes we think to have followed all steps showed in Apache Aries SPI Fly doc.
Felix console shows our bundles and their services, so it seems all right, but when invoking the constructor it logs error not finding any implementation, here follows the ServiceLoader invocation made in the third party library:
static {
ServiceLoader<IUtils> loader = ServiceLoader.load(IUtils.class);
Iterator<IUtils> iterator = loader.iterator();
if (!iterator.hasNext()) {
throw new ExceptionInInitializerError(
"No implementation found for IUtils in classpath, please choose between dss-utils-apache-commons or dss-utils-google-guava");
}
impl = iterator.next();
}
Thanks, bye

Hello Raffaele,
Have you read through the this page starting with
http://aries.apache.org/modules/spi-fly.html#making-it-work
Also, do you know exactly which ServiceLoader method is used in the Service Interface bundle? (it has to be the single argument ServiceLoader.load(Class) method to work with the OSGi standardized approach).
Sincerely,
- Ray

Hi all,
I would like to use a third party library in my Equinox, it makes use of ServiceLoader to loade an implementation coming from a different jar.
I created a bundle containing:
- my code which calls third party jar
- the third party jar containing the Service interface
- the third party jar containing the Service implementation
- the require and provide capability as suggested in Aries SPI Fly
I can see in my Felix console that bundle is active and I can see its service id, nevertheless when I invoke the getInstance of my class which in turn calls the third party code which calls ServiceLoader.load, the concrete class is not found :-(
Any help woulb be appreciated, thanks in advance, bye
