send push via urban airship using their web service (java) - push

Question

I have gone through the post
The code works fine for me. i need to do this using java, i tried using the HttpURLConnection and the javax.xml.rpc.Service but no luck.
I need to know how to do the implementation using java.

Answer 1

Solved it.
pushClient class:
public static void main(String[] args)
{
try
{
String responseString = "";
String outputString = "";
String username = "Application Key";
String password = "Application secret";
Authenticator.setDefault(new MyAuthenticator(username,password));
URL url = new URL("https://go.urbanairship.com/api/push/");
URLConnection urlConnection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection)urlConnection;
ByteArrayOutputStream bout = new ByteArrayOutputStream();
String postdata = "{\"android\": {\"alert\": \"Hello from JAVA!\"}, \"apids\": [\"APID\"]}";
byte[] buffer = new byte[postdata.length()];
buffer = postdata.getBytes("UTF8");
bout.write(buffer);
byte[] b = bout.toByteArray();
httpConn.setRequestProperty("Content-Length",String.valueOf(b.length));
httpConn.setRequestProperty("Content-Type", "application/json");
httpConn.setRequestMethod("POST");
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
OutputStream out = httpConn.getOutputStream();
out.write(b);
out.close();
InputStreamReader isr = new InputStreamReader(httpConn.getInputStream());
BufferedReader in = new BufferedReader(isr);
while ((responseString = in.readLine()) != null)
{
outputString = outputString + responseString;
}
System.out.println(outputString);
}
catch (MalformedURLException e)
{
e.printStackTrace();
}
catch (IOException e1)
{
e1.printStackTrace();
}
}
MyAuthenticator class:
private String user;
private String passwd;
public MyAuthenticator(String user, String passwd)
{
this.user = user;
this.passwd = passwd;
}
protected PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(user, passwd.toCharArray());
}
