http://java.sun.com/j2se/1.5.0/docs/guide/jar/jar.html#Service%20Provider Up to 1.5 the API is unfortunately not public (sun.misc.Service#providers(Class)), but starting with 1.6 it is: http://java.sun.com/javase/6/docs/api/java/util/ServiceLoader.html The 1.5 implementation of the API can easily be mimiced, it's about 50 lines, I've already done this in a project of mine.
