Question

I am trying to get an InputStream from a URL. The URL can be a opened from Firefox. It returns a json and I have installed an addon for viewing json in Firefox so I can view it there.

So I tried to get it from Java by:

URL url = new URL(urlString);
URLConnection urlConnection = url.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));

But it is throwing an IOException in urlConnection.getInputStream().

I also tried:

HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = url.openStream();

But no luck.

Any information is appreciable. Thanks in advance.

Thank you everybody. This is a weird problem but at last I solved it.

The URL I am requesting is

http://api.themoviedb.org/2.1/Movie.search/en/json/api_key/a nightmare on elm street 

Now browser replaces the spaces between “a nightmare on elm street” by “%20” internally and parses. That is why the requested server can response by that request. But From Java I didn’t replaced that spaces by “%20”, so it turns into Bad Request, source.

Now it is working.

BufferedReader reader = new BufferedReader(new InputStreamReader(((HttpURLConnection) (new URL(urlString)).openConnection()).getInputStream(), Charset.forName("UTF-8")));
