Java URLConnection Timeout

Question

I am trying to parse an XML file from an HTTP URL. I want to configure a timeout of 15 seconds if the XML fetch takes longer than that, I want to report a timeout. For some reason, the setConnectTimeout and setReadTimeout do not work. Here's the code:

          URL url = new URL("http://www.myurl.com/sample.xml");           URLConnection urlConn = url.openConnection();           urlConn.setConnectTimeout(15000);           urlConn.setReadTimeout(15000);           urlConn.setAllowUserInteraction(false);                    urlConn.setDoOutput(true);            InputStream inStream = urlConn.getInputStream();           InputSource input = new InputSource(inStream); 

And I am catching the SocketTimeoutException.

Thanks Chris

Try this:

       import java.net.HttpURLConnection;         URL url = new URL("http://www.myurl.com/sample.xml");         HttpURLConnection huc = (HttpURLConnection) url.openConnection();        HttpURLConnection.setFollowRedirects(false);        huc.setConnectTimeout(15 * 1000);        huc.setRequestMethod("GET");        huc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");        huc.connect();        InputStream input = huc.getInputStream(); 

OR

       import org.jsoup.nodes.Document;         Document doc = null;        try {            doc = Jsoup.connect("http://www.myurl.com/sample.xml").get();        } catch (Exception e) {            //log error        } 

And take look on how to use Jsoup: http://jsoup.org/cookbook/input/load-document-from-url

You can manually force disconnection by a Thread sleep. This is an example:

URLConnection con = url.openConnection(); con.setConnectTimeout(5000); con.setReadTimeout(5000); new Thread(new InterruptThread(con)).start(); 

then

public class InterruptThread implements Runnable {      HttpURLConnection con;     public InterruptThread(HttpURLConnection con) {         this.con = con;     }      public void run() {         try {             Thread.sleep(5000); // or Thread.sleep(con.getConnectTimeout())         } catch (InterruptedException e) {          }         con.disconnect();         System.out.println("Timer thread forcing to quit connection");     } }
