hypermedia ?

i got this example im trying to use as example so i can build my own and once im done i see that i cant even run it because i dont have this hypermedia file so my import hypermedia is giving my those errors for missing the lib, does anyone know where can i get this from ? i even have this issue using Processing where it wants this file on both p2 and p3 as well as Arduino sketch

The only pointer I could find for a 'hypermedia' library for Processing is: http://ubaa.net/shared/processing/udp/

If you want more help you will have to be more specific about which 'example' you are trying to use.
