Here are some powerEXT Core RPGLE examples to read and write JSON in
RPGLE. It can both read/write from http as either raw JSON or as POST data
within PARMS or from the IFS.

I think I'm going to have to compare take a closer look at YAJL to
properly compare it to JSON from rpgnextgen.com. The latter is
attractive because it is written entirely in RPG and the procedure names
seem a bit more intuitive (e.g. json_parse() compared to
yajl_tree_load_buf() ) - however as YAJL is, I believe, written in C it
might bring some performance benefits.

Raul,

I don't understand your complaint about calling QtmhRdStin? it's an

extremely simple call, and then your JSON data is loaded into a variable in
your program, and you can parse it. What could be simpler?

If you're interested in YAJL, you can use the yajl_tree_load_buf()

procedure to load the buffer you got from QtmhRdStin() to parse the JSON,
and then you'll have a yajl tree that you can extract the data from.
There's info on parsing XML with yajl in the following handout (this is
from talks I give on yajl):

http://www.scottklement.com/presentations/Working%20with%20JSON%20in%20RPG.pdf

I've been considering adding a wrapper to my YAJL tools that does the

call to QtmhRdStin() for you so you don't have to code it by hand -- this
wouldn't save you all that much, really, just eliminates the need to code
it each time. Would that be more attractive to you? (That's basically
what CGIDEV2 does, after all.)

CGIDEV seems to ignore this data. With another company I used
QtmhRdStin, but I wonder if there is an easier way to read it.

I installed YAJL from Scot's site, but it seems that is great to

create

json and to parse it, but I did not find how to receive it.

According to this: http://www.w3.org/TR/html-json-forms/ browsers

will

be able to send json encode data.

Here is part of the document they send me.
