I'm having some problems with Processing Environment. I'm actually using Foursquare Java Library V2 ( https://code.google.com/p/foursquare-api-java/). This code is the basic example found in the project wiki page, but I can't figure out how to run it!

It gives me an error like this
Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: org/json/JSONException

I googled this kind of error and It's caused by a wrong definition of the java CLASSPATH.

Can anyone give me any hint. How I can fix it?

1.    String id = "***";
2.    String secret = "***";
3.    String callback = "***";
4.  public void searchVenues(String ll) throws FoursquareApiException {
5.    // First we need a initialize FoursquareApi.
6.     FoursquareApi foursquareApi = new FoursquareApi(id, secret, callback);
7.    
8.     // After client has been initialized we can make queries.
9. Result<VenuesSearchResult> result = foursquareApi.venuesSearch(ll, null, null, null, null, null, null, null, null, null, null);
10.    
11.     if (result.getMeta().getCode() == 200) {
12.       // if query was ok we can finally we do something with the data
13.       for (CompactVenue venue : result.getResult().getVenues()) {
14.         // TODO: Do something we the data
15.         System.out.println(venue.getName());
16.       }
17.     } else {
18.       // TODO: Proper error handling
19.       System.out.println("Error occured: ");
20.       System.out.println("  code: " + result.getMeta().getCode());
21.       System.out.println("  type: " + result.getMeta().getErrorType());
22.       System.out.println("  detail: " + result.getMeta().getErrorDetail());
23.     }
24.   }
25.  
26.   
27.   
28. void draw(){
29.   try{
30.    
31.     searchVenues("45.49985,9.191093");
32.  
33.     }catch (Exception e) {
34.      e.printStackTrace();}
35. }

Did anyone tried to play with foursquare with processing?
I'm trying to get a csv file of all check-in during the day in an area.

Can someone help me? There are some scripts or some tutorial?

Thanks!

Here is a sketch I have been using to do a geoLocation search using the twitter4j library. I'm tring to get all the possible tweets from a location focusing only on the coordinates of the tweet. My goal is to get the exact position of the people during the day using twitter.

I created a loop to make the query every 10,4 sec (in order not to reach the twitter-rate limit) but there's something wrong.
I've done some tests tweeting from within the query coordinates but I can't get these tweets back in the output code.

Can anyone point me in the direction as to why?

Any advice or help would be appreciated
