  We study the effect of magnetic impurities in the d_{x^2-y^2}-wave
superconducting (SC) state of the two dimensional t-J model.The spin-orbit and
the spin-exchange interactions are examined by treating the impurity as a
classical spin. The Bogoliubov de Gennes equation derived within a slave-boson
mean-field approximation is solved numerically at T = 0. The spin-exchange
scattering induces spin-triplet p-wave SC order parameters near the impurity,
while a SC state with broken time-reversal symmetry and a spontaneous current
appears in the presence of the spin-orbit interaction. When both interactions
coexist, it turns out that a state which carries a spontaneous spin current
occurs.
