Hi all! I need to use the mostpixelsever library to make a processing program.
http://code.google.com/p/mostpixelsever/downloads/list <-- here the libraries

I've just dowloaded and installed Server_TCP_v3.zip and ProcessingLibrary_TCP_v4.zip but processing gives me this error:

I think that processing can't launch the server but i'm not sure of this.
Somebody knows how can i fix this?

The processing program is
