to apply for asylum in a european country you need to be in Europe. So if you want to apply for asylum in Germany you would legally need a visa for germany, in order to be able to take a flight and go there.
To get this visa you need to go to the german embassy in Amman. They will only take care of your visa if you have a jordan citizenship, if you are from syria, from Irak or from Jemen (http://www.amman.diplo.de/Vertretung/amman/de/04-rk/visabestimmungen/InfoMerkblaetter.html#topic8
Unfortunately, to get a visa for germany you will need to prove that you can pay your insurance and all the costs by yourself. So they want prove about a lot of money (http://www.auswaertiges-amt.de/DE/EinreiseUndAufenthalt/Visabestimmungen_node.html#doc350344bodyText7
If you tell me where you are from, I can translate the information of the website to you and tell you which documents you need to apply for visa.
In any case, you will need an appointment at the embassy, which you would need to make through this website: http://www.amman.diplo.de/
I hope this answers your question!
