java - JSON with HttpURLConnection not working on PUT -

-

i stuck when working json in java application. quite newbie both json , httpurlconnection, doing basic wrong. have tried quite lot of things , i'm not able find error, can me.

i trying put call aganist server. code. 

//desired json string: [{"type":"url", "parsed_data":"testdata"}] string infotojson = "[{\"type\":\"url\",\"parsed_data\":\"testdata\"}]";  string uri = "www.myuri.com" string user = "myuser"; string password = "mypass"; string userpass = user + ":" + password; string encoded = new sun.misc.base64encoder().encode(userpass.getbytes("utf-8"));  url url = new url(uri); httpurlconnection connection = (httpurlconnection) url.openconnection(); connection.setrequestproperty ("authorization", "basic " + encoded); connection.addrequestproperty("accept", "application/json"); connection.addrequestproperty("content-type", "application/json"); connection.setdooutput(true); connection.setrequestmethod("put");  outputstream out = connection.getoutputstream(); out.write(infotojson.getbytes("utf-8")); system.out.println("error: " + connection.getresponsecode()); out.close();

the user/pass verified work, on "get" method.

i keep receiving "error 400" code, have not been able identify particular problem.

i have feeling problem related "infotojson" variable in way or another: codification of json string, char encoding or similar. however, have not been able find problem after million tests.

any hint on this?

edit: code has been corrected hgoebl suggestions, current version working one.

i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
