What the o.p. is describing is traditional methods that 'mostly' work fine, particularly when performed by people who've been taught by other lifetime-experienced people and so forth.
What most other posters are describing is the modern USDA food science type approach, which is aimed at getting the success rate higher than 'mostly' and aimed at people who are learning to do it on their own. (e.t.a. - I'm not sure how completely it *succeeds* at either of those things, but that's its *goal*)
It is a personal choice, what level/type of risk you're comfortable with.
Y'all, fruit IS ALREADY ACID ENOUGH to prevent growth of botulism bacteria. (Well, nearly all fruit. There are some exceptions, e.g. figs and ripe bananas and so forth).
The waterbath-processing of canned fruits and jam and suchlike IS NOT what makes it safe from botulism -- when botulism is a concern i.e. in low-acid foods, it requires a pressure canner, or very very long waterbath canning plus a certain degree of faith and luck. Waterbath processing merely helps kill off the smallish number of other spoilage microorganisms that can thrive in high-sugar environments, and also aids in the formation of an airtight seal.
