in reply to Perl, Android web app, AJAX, JSON

monx, your situation is actually a familiar one, and the somewhat old-school description of it was once called, “screen-scraping.”   (This made complete sense, I suppose, “way back” when we were first attempting to connect computers to legacy applications that expected to be talking to dumb terminals.)   In 21st-Century terms, this question would now be, “do I want my mobile-app to pretend to be a web browser, as seen by this legacy application web-site which expects to be talking to a dumb terminal a browser?

A very-serious and very-immediate issue that will very-immediately face you is the following:   “possibly-mountains of JavaScript,” which the legacy application existing web-site may well expect the browser your application to be able to execute, all of this being the actual(!) legacy- interface to the application.   Truly, you need to find this out as soon as possible.

Also:   It actually does not matter diddly-squat what host-side(!) language your legacy application web-site was “written in,” simply because present-day web applications actually consist of an entirely-unpredictable “mash-up” of host-side vs. client-side behaviors.   (FaceBook® was originally implemented in PHP, but who-the-hell knows or cares?)

Ahem ...

Without further pretenses, and without the slightest concerns about the “flood of down-votes” that such statements will now certainly bring from The Peanut Gallery™, I am now going to put on my consultant’s hat, and bluntly tell you something that you probably do not want to hear:

Any Mobile Application is n-o-t (merely ...) “a front-end to what already is there.”   Nope, Sorry.   It is entirely separate application(s), and must be project-planned as such!

You think that your situation is somehow an exception.   Yes, you do.   Of course you do.   (They all do.)   You think that the fact that the back-end “is implemented in ‘Perl’” actually makes a difference.   (And, you right-now seem to be supported by a you-just-cant-get-rid-of-em cloud of mosquitoes who insist that sundialsvc4 can’t possibly know his asterisk from a hole in the ground be possessed of even one single thought worth thinking ... but, I digress.)   I feel your pain.   If When you want to hear more, please message me privately.   There is still time.

    Plenty of mobile applications are exactly a front end to what was already there. It's bizarre to assert otherwise.

    When you want to hear more, please message me privately. There is still time.

    Maybe I was wrong when I asserted that your posts weren't spam because that sure looks like solicitation.

    What does this look like? Thirty-three bear your mark right now and it will probably be thirty-six tomorrow since you have three new posts right now that do not offer code, answers, links, references, or anything on point for the OPs in question.

    (update: missing word added.)

    "There is still time."

    There is also still time for you to reply to chromatic who again points out your fundamental failings to understand what you're talking about, or back up more of your wild baseless claims.
