lookup third party service impl of an interface

If you have a jar file containing implementations of an interface that you want to be discovered by lookup...here's what you do:

1) Use library wrapper wizard in Netbeans to create a jar module wrapper.
2) Create a folder META-INF/services in the wrapper module.
3) Create a file in META-INF/services named after the fully qualified name of the interface containing the fully qualified names of the implementations (one per line)

That's it!
Third party service implementations to now be discovered by the global lookup on startup.
