415 Error when Uploading file using Jersey Servlet

Question

When uploading a file using test.html, I get a HTTP 415 error, unsupported media type. It appears something is not working correctly with multipart in jersey. In the console of my server, I get the following error:

No message body reader has been found for class org.glassfish.jersey.media.multipart.FormDataContentDisposition,
    ContentType: multipart/form-data;boundary=----WebKitFormBoundaryFwksqvOnuCUBmh87

After doing some research on the web and other StackOverflow articles, I couldn't find an appropriate solution. One of the recurring themes I've seen is about registering the Jersey multipart feature, but I'm not clear on where or how to do that within my file structure. I think I'm close to a working solution, but not there yet. Here's my code currently:

First of all, remove the @ApplicationPath annotation from the UploadFiles class. Use only @Path to define a resource class.

Create a class that extends Application or ResourceConfig, annotate it with @ApplicationPath and then register the MultipartFeature class:

@ApplicationPath("/api")
public class MyApplication extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<Class<?>>();
        classes.add(MultipartFeature.class);
        return classes;
    }
}

@ApplicationPath("/api")
public class MyApplication extends ResourceConfig {

    public MyApplication() {
        register(MultipartFeature.class);
    }
}

You may also need to register your resource classes too. For details on Application, refer to this answer.
