drawLine da client a server

[PipinoPiranha™]

Salve a tutti,

ho un problema con la comunicazione tra due applet. Voglio far sì che quando disegno nell'applet client con drawLine, allo stesso tempo nell'applet server appaia il disegno... Ma non funziona! Tuttavia l'invio delle coordinate sembra funzionare (vedi showStatus applet server). Qualcuno che mi può aiutare gentilmente? Domani ho un esame, sarebbe il massimo farlo funzionare entro sera.

Sotto i codici dei due rispettivi applet.

Grazie mille!
