So, other people have already answered this, but this does seem to be a gap where many developers lack some piece of knowledge to chain the whole solution together. You normally package this sort of thing by putting the native library in a jar, extracting it to a tmp file that will be deleted on exit, and opening that dynamic library.

I’ve met many perfectly reasonable developers who do know all those steps can be done but can’t put them all together - maybe because it just hasn’t clicked that you can store a library in a jar. It feels like something tutorials should cover, but I think falls into the, “surely everyone can work it out?” category.
