With the amplitudes derived from the lowest order chiral Lagrangian as the kernel of a set of coupled channel Bathe-Salpeter equations, the $I=1/2$ $S$ wave $K\\pi$ scattering phase shifts below 1.2 GeV can be fitted by one parameter, a subtraction constant, and a scalar resonance corresponding to the controversial $\\kappa$ ($K^*_0(800)$) can be generated dynamically. A good description of the $I=3/2$ $S$ wave $K\\pi$ scattering phase shifts below 1.2 GeV can also be obtained.
