Built-in JSON parser in J2ME?

Question

I'm developing an application (MIDlet) for the Gemalto EHS6 modem, which runs java micro edition. I want to make an HTTP post using the JSON format. What would be the easiest way to do this?

org.json is not supported in J2ME

I've already read these answers, but I can't believe that would be the way to do it!? Depend on some 3rd party implementation? I could write a simply one myself only for the subset of the JSON format I need - But this does not seem like the "right" choice. Or what? Is that the most efficient way of doing it in the end?

As far as I know there is no plan to add built-in support for Json on J2ME. But you may try using/porting https://jsonp.java.net/ — Telmo Pimentel Mota, Jun 27 '16 at 11:35

Yes, there is an API for JSON in Java ME. You can see it in the section Oracle Java ME Embedded APIs, the package name for that is com.oracle.json. It is available since the 8.0 release.

The main problem for you is that the modem you mentioned supports only Java ME 3.2 judging by its web page. Unless you know a way to upgrade it to the 8.0 release or higher, I'm afraid you're stuck with using your own libraries.

Great answer! In my case, however, I don't know if I could/should do that. The modem runs a lot of firmware from Gemalto, providing security and maintenance - so an upgrade would probably leave me without their support. – Clausen Jul 19 '16 at 07:36
