I tried to send an xml to an url its ,
throwing error when its tries to opens connection to the URL (url.openStream())

URL url = new URL("http://xx/yy?xml=test xml");
connection.setDoOutput(true);
connection.setDoInput(true);
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));


But when i tried to connect to the url directly from the browser i could able to connect.Only through the code i'm getting the error.

 
java.net.ConnectException: Connection timed out: connect

Please help me..
thanks you.

HTTP is a request-response protocol. Many servers will not start to process a request until the client opens the response. Try reading from your BufferedReader.

[Neeba Rebbaca]

I'm reading only from,

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

[Rob Spoor]

You create the reader, but do you also read all data from it?

[Neeba Rebbaca]

Yes, i tried to read,

  
String decodedString="";
            while ((decodedString = in.readLine()) != null) 
            {
                responseXML = decodedString;
                System.out.println(decodedString);
            }
            in.close();

But i'm getting error at this place itself,
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

[Ulf Dittmer]

Is the server reachable from the machine where this code is run? Meaning, can you retrieve that URL by copying it into a browser?

[Neeba Rebbaca]

same url can be accessed and able to get reply from browser , the problem comes when trying to connect from code

[Rob Spoor]

Are you using a proxy in your browser? If so, you must also use that proxy in your code:

URL url = ...;
Proxy proxy = ...;
URLConnection connection = url.openConnection(proxy);
...
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));

[Neeba Rebbaca]

Yes, i'm using Proxy address for connecting to internet,

Is this is the way to set Proxy,

   
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("123.0.0.1", 8080));
URLConnection uc = new URL(url).openConnection(proxy);

[Rob Spoor]

That looks alright to me.

[Neeba Rebbaca]

but still its throwing same (timeout error) at this line,

  
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

[Rob Spoor]

That's because url.openStream() is shorthand for url.openConnection().getInputStream() - and therefore does not use the proxy. In my code example I've shown you to use connection.getInputStream() instead.

[Neeba Rebbaca]

How to get the proxy address dynamically.Because if i put the code in some other system the proxy may change.

[Rob Spoor]

I don't think you can get that without using either JNI or the registry.

[Neeba Rebbaca]

The has been solved.thanks for your valueable input and time.

[Rob Spoor]

Do you care to tell us how you did this?
