In terms of food safety, oven processing fruit and fruit jams is no more risky than the hot water bath method. The reason for that is simple. No open cattle will reach above the boiling point of 100°C or 212°F. Keep in mind though that low acid or non-acid foods should never be processed by any other than the pressure canner method. However oven processed fruits and fruit jams are just as safe as those processed in the hot water bath.
