Weeping cherry trees can ooze sap for no particular reason, but most often the oozing sap is a symptom of injury. Boring insects, birds pecking, or even weather related bark splits can provide a weak area where sap can escape. The sap usually crystalizes which generally will stop the flow of sap so it won't always be a problem. There is a disease called gummosis that can also cause the oozing sap but if your tree looks otherwise healthy, it may not be an issue. Just continue to give your tree good care and watch for browning leaves, lesions, calloused over areas, etc. which might indicate a disease problem.
