The fastest method is to crack the seed open with a vise or pair of lock grip pliers. The dried fruit should be ready to crack and use now but the seed of the fresh fruit should be dried and cold stratified in the refrigerator for a couple of months. With regular pliers you may smash the seed kernels so use something that will not go too far and smash the seeds. Carefully remove the kernels and plant barely below the surface in a 1 gallon pot with a NO fertilizer potting soil. Put a gallon plastic bag over the top and secure with a rubber ban or you can use one of those mini greenhouses. The seeds should sprout in about a week or two at the most. Keep them away from direct sun until they are sprouted and growing a little. Remove the plastic bag also when they are a couple inches tall. Then put them under a bright light (or they will get leggy) or outside in a shady place if it is not too cold at night. When they go dormant, (still in the pot) the end of the first year, plant them outside in the ground.
Alternately, you can just barely crack the seed and plant then directly in the ground. They should come up the next spring (if cracked).
Now to seed viability, not all jujube seed are viable (will grow). Without cross pollination they will not be viable. Seeds of Li and Lang are usually not viable for an example (most fresh fruit sold in this country is Li variety.)
Be sure the dried fruit did not come from India. The Indian ber (jujube) is not cold hardy.
Seedling plants usually take 3-5 years to bear fruit, whereas grafted plants usually produce fruit by the second year (sometimes the first year.)

I hope this helps.

I've read that jujubes will fruit within a few years when raised from seed,
so I went to the Chinese market and purchased both fresh and dried fruit. I
was wondering if someone here has raised jujubes this way and could give
some advice/pointers on successfully germinating these seeds. I've read that
the seeds from dried fruit are not viable, that the outer covering must
first be cracked to release the 2 seeds inside, that the seeds must first be
incubated for 2 months and then cold stratified for 3 months. Is any of this
true in practice?
