title: set proxy in java
body: <p>I create a service that post something through the internet and everything's fine. But when I deploy it to our server I get connection status:403, forbidden. I think it is because our server won't allow direct access to the internet without login first. We have to login first in the browser with our username/password to access the internet.</p>
  
  <p>I notice that if I have login and access the internet in the server, the service I deploy run alright. But I don't think it's practical because in that case my service won't run if someone or I don't login first.</p>
  
  <p>I have tried setting the proxy in the java code but to no avail. Could someone help me with this problem? Here is I post my service snippet.</p>
  
  <pre><code>System.getProperties().put("http.proxySet", "true");
  System.getProperties().put("http.proxyHost", myHost);
  System.getProperties().put("http.proxyPort", "8080");
  System.getProperties().put("http.proxyUser", myUser);
  System.getProperties().put("http.proxyPassword", myPassword);
  System.getProperties().put("http.nonProxyHosts", "localhost|127.0.0.1");
  
  try {
              URL url = new URL(urlAddress);
              HttpURLConnection con = (HttpURLConnection) url.openConnection();          
              con.setRequestMethod("POST");
              con.setDoOutput(true);
              con.setDoInput(true);  
  
              ...
  
              if (con.getResponseCode() == HttpURLConnection.HTTP_OK) {
                  System.out.println("connection OK");
                  istrm = con.getInputStream();
                  if (istrm == null) {
                      System.out.println("istrm == null");
                  }
  
                  ...
  
              } else {
                  System.out.println("Response: " + con.getResponseCode() + ", " + con.getResponseMessage());
              }
  }
  </code></pre>
  
  <p>And my process goes to else block and gets response message 403   </p>
