You have to get a classloader, and test whether it’s a URLClassLoader. If so, downcast and get its URLs. From there, open each as a JarFile and look at its entries. Apply a regex to each entry and see if it’s one that interests you.
Clearly, this isn’t fast. It’s best to be given a name to be looked up in the classpath, perhaps listed in a standard file name in the META-INF directory of each classpath element, similar to the technique used by the ServiceProvider facility. Note that you can list all files with a given name on the classpath.
