3 differences between Jazz playing and Classical playing that will help you:
1) In Jazz, some lower lip must cover the bottom teeth, but only about half as much as in Classical playing: this helps form the “sub-tone” embouchure which allows for more overall flexibility.
2) In Jazz, there is an symmetrical amount of mouthpiece in your mouth: the upper teeth are covering more of the top of the mouthpiece than the bottom teeth/lip are covering the reed
(this is also necessary for the flexible "sub-tone" embouchure).
3) In Jazz, the embouchure (and jaw) is more flexible than in the Classical style: in order to accent hard enough, you may need to move your embouchure.
LISTENING and IMITATING are 2 essential parts of learning style.
I have recorded each of these jazz style studies so that you can listen to them a lot and also play along with them a lot (while wearing HEADPHONES, OF COURSE!).
