Based on the recently considered classical string configurations, in theframework of the semi-classical limit of the string/gauge theorycorrespondence, we describe a procedure for obtaining exact classical stringsolutions in general string theory backgrounds, when the string embeddingcoordinates depend non-linearly on the worldsheet spatial parameter. Thetensionless limit, corresponding to small t'Hooft coupling on the field theoryside, is also considered. Applying the developed approach, we first reproducesome known results. Then, we find new string solutions - with two spins inAdS_5 black hole background and in AdS_5 x S^5 with two spins and up to nineindependent conserved R-charges.
