HttpURLConnection POST, conn.getOutputStream() throwing Exception?

The URL simply cannot be reached. Either the URL is wrong, or the DNS server couldn't resolve the hostname. Try a simple connect with a well-known URL to exclude one and other, e.

G InputStream response = new URL("stackoverflow.com").openStream(); // Consume response Update as per the comments, you're required to use a proxy server for HTTP connections. You need to configure that in the Java side as well. Add the following lines before any attempt to connect to an URL System.

SetProperty("http. ProxyHost", "proxy.example. Com"); System.

SetPropery("http. ProxyPort", "8080") It suffices to do this only once during runtime See also: Java guides - Networking and proxies.

Java.net. SocketException: Operation timed out: connect:could be due to invalid address tells everything. – ckuetbach Jan 27 at 13:30 I have a FORM in a html file that makes a POST to the same exact URL and it works.

What gives? – Blitzkr1eg Jan 27 at 13:34 1 You mean, in a normal webbrowser? If so, does it use a HTTP proxy server?

If so, you should configure that in Java side as well. – BalusC Jan 27 at 13:35 Yes! That must be it!

Trying now – Blitzkr1eg Jan 27 at 13:36 OK, I updated the answer to add more detail about how to achieve this in Java end. – BalusC Jan 27 at 13:40.

Without establishing the connection (which in this case requires 1 more step to be performed ie connect), transfer is not possible. Connect() should be called after the connection is configured (ie after being done with the set***() on the connection).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
