Here is some sample java code you can use to post updates to Twitter from java. This is just a simple POST method, if you are looking for a full Twitter library head to Twitter Development Talk. I implemented this code on the OraTweetBot which I will make available soon.
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.InetSocketAddress;
import java.net.SocketAddress;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
public class Main {
public static void main(String[] args) {
SendTwitter(args[0]);
}
public static void SendTwitter(String msg ) {
try {
int proxyon = 1;
String proxyurl = "www-yourproxy.com";
int proxyport = 80;
String twitteruser = "username";
String twitterpass = "password";
SocketAddress addr = null;
java.net.Proxy proxy = null;
URLConnection connection = null;
String credentials = twitteruser + ":" + twitterpass;
if (proxyon == 1){
addr = new InetSocketAddress(proxyurl, proxyport);
proxy = new java.net.Proxy(java.net.Proxy.Type.HTTP, addr);
}
String encodecredentials = new sun.misc.BASE64Encoder().encode (credentials.getBytes());
URL url = new URL("http://twitter.com/statuses/update.xml");
String encodedData = URLEncoder.encode(msg, "UTF-8");
if (proxyon == 1){
connection = url.openConnection(proxy);
}
else{
connection = url.openConnection();
}
connection.setRequestProperty( "Authorization", "Basic " + encodecredentials);
connection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write("status=" + encodedData);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String decodedString;
while ((decodedString = in.readLine()) != null) {
System.out.println(decodedString);
}
in.close();
} catch (Exception e) {
System.out.println(e.toString());
}
}
}
