Title: [jdjlist] HttpURLConnection timeout

Thanks Madhu, I believe you're right. Unfortunately, like I said in my post, this is an app server issue, not WebServer (like Apache).

 

Anyone tried to use disconnect() method? I'm trying that now.

 

I don't want to download third-party libraries for this, but I am about at my wit's end. 

 

G*d, is this not a classic example of Sun's pig-headedness?  Did they not think someone's going to actually USE their classes?  For something actually remotely USEFUL, like Web Services?  How can they promote WS if they don't even provide a timeout on their connection API?????

 

ARGH!!!!

I guess this is a configurable parameter on the WebServer.

Checking with the admin docs of your WebServer might help...

Dear All:

How do I set the timeout for an HttpURLConnection running from a server? i.e. if it did not get the response back in stipulated time, drop the connection?

This is my server connection code, look for a FIXME note. I found lots of notes about the Servlet utilities for this, but little about the server-based URL connections.

Thanks!

Greg

            //begin open URL
            URL url = new URL(urlString);      
            conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod(POST);
            conn.setAllowUserInteraction(false); // you may not ask the user
            conn.setDoOutput(true);              // we want to send things
            conn.setDoInput(true);               // we want recieve things
            conn.setUseCaches(false);            // turn off caching

            //the Content-type should be default, but we set it anyway
            conn.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
            //fixes Netscap bug?? Do we need this?
            //conn.setRequestProperty("User-Agent","Mozilla/4.7 [en] (Win98; I)");
            //the content-length should not be necessary, but we're cautious
            conn.setRequestProperty("Content-length", Integer.toString(body.length()));

            OutputStream rawOutStream = conn.getOutputStream();      
       
            out = new DataOutputStream(rawOutStream);
            out.writeBytes(body);
            out.flush();
            out.close();

            // get the input stream for reading the reply
            // IMPORTANT! Your body will not get transmitted if you get the
            // InputStream before completely writing out your output first!

            //FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  FIXME!!  put some type of the timeout code here!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?

            InputStream  rawInStream = conn.getInputStream();
            in = new BufferedReader(new InputStreamReader(rawInStream));

            String inputLine;
            while ((inputLine = in.readLine()) != null)
                responseMessage.append(inputLine);

            in.close();
