Border crossing from Jordan-Israel-Jordan

I Will have to go to Jordan in 3 weeks. After that I will have to go to the Israel and then again to Jordan. I dont know if I will have problem with crossing border. So I need advice from the first hand. Can someone tell me something about Border crossing from Jordan-Israel-Jordan? Thank you in advance.

What is nature of your trip? I mean ,do you go there for business or for pleasure? If you are going for business I dont think that you will have problem. Firm that you are working with in Israel, can give you guarantee letter. But people that work on Jordan border can make you some problems. I dont have experience with this kind of things. But I have heard that people had problem on Jordan Border. I think that you can get visa on Israel border. At least I heard that information. It doesnt have to be true.
