All of the below suggestions assume you have a center stand. Start with the bike on the center stand.
If the jack is small enough, then position it under the front brace that is in between the frame down tubes. Use a piece of wood to cushion it.
If you cannot get the jack under the front brace, then get another person to press down on the rear of the bike to raise the front while you position a block of wood under the front brace.
If you have a very heavy object available, then you can also use a ratchet type tie down to pull the rear down to raise the front.
If you are in a garage, then use a ratchet type pull up that is connected to the rafters of the garage.
If you have a heavy friend, then invite them over for a beer and ask them to sit on the back of the bike to raise the front while you change the front wheel.
You can let the front down on a block of wood if you are going to have the wheel off for a while.
You can also remove the brake caliper and speedo cable and remove the axle nut and loosen the two nuts on the left side with the bike just sitting there. Then, if you are really quick, just lift the front and pull the axle out and then the wheel.
