It's a basic web service, whose core is already written in B4X.
I was wondering if I could leverage the already existing code, while continuing to maintain it in its current language.
It looks like I'm going to learn a new language, since it won't be a one-shot job, rather than something that will be maintained over time.
Anyway, the reason behind it, is that the hosting company allows only php code, not java: a jserver project would have already solved the issue.
