How use Java ServiveLocator with One-Jar

Question

I'm packaging an application of mine in a single jar using the One-Jar tool:

http://one-jar.sourceforge.net/

It works nike, but I have a problem with a service implemented in a dependency module, which is implemented in a separate jar.

The module uses the standard Java ServiceLoader mechanism to provide its service ie the jar has a file META-INF/services/package.name.ServiceProviderClass which specifies the service concrete class to be instantiated.

BUT when this jar is embedded in the application "fat-jar", created by One-Jar, the the service it is NOT discovered by the service loader mechanism.

Any idea how to make it work?

Cheers, Paolo

At the end I solved this problem by using Capsule packaging in place of One-jar
