How do I sterilize a Fido like jar? The one with the rubber and clamp?

I just bought a jar with a rubber insert and a clasp for canning. I plan to make a hot pepper jelly. I need to know how to boil it. I know I remove the rubber but do I leave the jar opened or closed? How long do I boil it for? Do I put the Jelly in while the jar is hot?
 
Leave the jar open and you can sterilize the rubber to, just not for as long as the jar. Do it quickly. It doesn't matter if you put the jelly in while its hot.
