No, no, no!
You need either the wax discs (put on while the jam is HOT and then cover with the cellophane tops and elastic bands) OR metal lids - not both!
I have been judge of preserve making for many years and it's a matter of one or the other!
IMOH your best bet is to use the pop-up lids - you know, the ones with the funny bit in the middle that goes 'pop'when you have a seal. Re-use what you've got after bleaching them..........
A microwave is good for sterilising but, if you haven't got one, boiling water will do............ Whatever you do, jam/jelly will only keep well for a year. Yes, I know people will say they have kept grannies jam for umpty-ump years...............
