Soliton solutions of (2+1)-dimensional soliton equations have received renewed interest in recent years, and several works have showed that these solutions describe a rich phe nomenology of soliton interactions [1-11].The phenomenon of soliton resonance was first discussed in the context of the Kadomtsev-Petviashvili (KP) equation [10] (see also [11]).Recently [1-4,6,9], more general resonant solutions of KP, which possess a web-like struc ture, have been studied.
