Curl(E cross H)=H (curl E) E(Curl H)
H ( dB/dt ) E( J+ dD/dt)
for some reason they say J=0 , I don't get why?

J depends on what material is used. In free space there are no electric charges, and hence J equals to zero.

(same answer as Anonymous1921) If you use this equation with reference to an electromagnetic wave travelling in a vacuum, there is not current there, so J = 0
