  The special role of the isoscalar mesons ($\sigma$ and $\omega$) in the NJL
soliton is discussed. Stable soliton solutions are obtained when the most
general ansatz compatible with vanishing grand spin is assumed. These solutions
are compared to soliton solutions of a purely pseudoscalar Skyrme type model
which is related to the NJL model by a gradient expansion and the limit of
infinitely heavy (axial-) vector mesons.
