While @paul-samsotha's answer is correct, still there is implementation trick. I want to share it and hope it will help someone.

a) Implement your mapper:

public class MyExceptionMapper implements ExceptionMapper, ResponseErrorMapper {
    ...

b) make sure you declare generic type, otherwise your mapper will never be called

public class MyExceptionMapper implements ExceptionMapper/* no generic declaration */, ResponseErrorMapper {
    ...

and may trigger

javax.ws.rs.ProcessingException: Could not find exception type for given ExceptionMapper class: class com...MyExceptionMapper.

c) Register it as resource:

ResourceConfig config = new ResourceConfig();
config.register(new MyExceptionMapper());

or

config.register(MyExceptionMapper.class);

d) make sure you enforce processing errors as well:

config.setProperties(new LinkedHashMap() {{
    put(org.glassfish.jersey.server.ServerProperties.PROCESSING_RESPONSE_ERRORS_ENABLED, true);
}});
