that's great! thanks so much.

Its a bit of a shame that there's no examples. Could you update providing at least one example of usage? Thanks

I most certainly can! =)

(it's now on my to-do list)

There's one way here below...

Remember:

You have to change the baseURL (line 2).

When calling

1. entry.getString("landeskirche")

etc.
you have to change Code according to the names of your APIs items ("landeskirche"...)...
 - occurs often.

This line

1.   String request = baseURL + "d=" + trim(str(intCurrentMonth));

is obviously depending from what your API wants.

That line is unnessary / wrong sometimes:

1.   // make String (might be unnessary sometimes)
2.   result = "{ \"items\": " + result + "}";

Good luck!   

1. import org.json.*;
2. String baseURL = "http://www.ekd.de/reformation-und-musik/api366+1.php?";
3. int intCurrentMonth = 3;
4. PFont myFont;
5. void setup() {
6.   size(800, 700);
7.   // Create the font on the fly
8.   myFont = createFont("Sans Serif", 18);  
9.   textFont(myFont);
10.   fill(0);
11.   Output();

That's a good working example of connecting to a service that uses JSON. Could probably have used a service that was a little bit easier to understand though. There's a lot of things going on there, and a lot of data - which can easily get frustrating for people new to JSON (and formatted text in general). =)

Thanks for the reply Chrisir

Started adding examples while also removing exceptionhandling from the Processing side. Some functions still require exceptionhandling though... so beware!

(If anyone wants to help out with this lib, just give me a shout)

I've updated the library again, removing some more exception handling and added a new example to parse HTTP headers.

thank you sooo much!!! really appreciate!

I have added an example on how to write JSON files using the library.

The JSON library does not run on Android Processing, it gives me this error message:

Until Ben and co. have decided on an implementation for the core JSON library I've updated my temporary lib. It has a new, more Processing-aligned, workflow using just one JSON type instead of JSONObject and JSONArray.

Examples have been updated, unfortunately some examples were removed for various resons (f.ex. the Yahoo weather have removed the option to render json).

The new library can be downloaded at https://github.com/agoransson/JSON-processing (you find the new download link for the latest version in the text)

Apologies for the late reply.

You're doing everything perfectly correct!
There was a bug, the thing was parsing correctly but the type wasn't being set. So it thought it had failed to parse. It should be updated now (it's still version 0.1.6 so make sure to replace everything when you install).

Thanks for letting me know.

Great !

You shouldn't need the try-catch anymore. I switched to the JSON classes found in processing core, which had their JSONExceptions removed.

Have now updated version again, fixed a recursion problem with the opt() method (something you never use) and also included a first fix of the XML to JSON conversion with an example built on Shiffmans "Loading XML Data".

Current version 0.1.7
