I am trying to write a java class that will submit an XML request to the EMServiceServlet.
 
What I have now returns a 500 Internal Server Error, just like if I were to visit the servlet with a web browser.
 
So I think my problem is with my headers, but I can't be sure.
 
Does anyone see anything wrong with my code?
 
 
import java.io.*;
import java.net.*;
public class EMLoginLogout {
 public static String emLogin(String userid, String phoneName, String appID, String appPasswd) {
 // Build XML String
 String XMLString = new String();
 XMLString = "<request>";
 XMLString += "<appInfo>";
 XMLString += "<appID>" + appID + "</appID>";
 XMLString += "<appCertificate>" + appPasswd + "</appCertificate>";
 XMLString += "</appInfo>";
 XMLString += "<login>";
 XMLString += "<deviceName>" + phoneName + "</deviceName>";
 XMLString += "<userID>" + userid + "</userID>";
 XMLString += "<exclusiveDuration>";
 XMLString += "<time>60</time>";
 XMLString += "</exclusiveDuration>";
 XMLString += "</login>";
 XMLString += "</request>";
 try {
  // Make connection
  URL url = new URL("http://X.X.X.X:8080/emservice/EMServiceServlet");
  URLConnection urlConnection = url.openConnection();
  urlConnection.setRequestProperty("Content-Type", "text/xml; charset=\"utf-8\"");
  urlConnection.setDoInput(true);
  urlConnection.setDoOutput(true);
  urlConnection.connect();
  OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream(),"UTF8");
  
 
  // Write XML string to request body
  out.write(XMLString);
  out.flush();
 // Read the response
 BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
 String line = null;
 while ((line = in.readLine()) != null)
 {
  //System.out.println(line);
  line += in.readLine();
 }
 out.close();
 in.close();
 return line;
 }
 catch (UnknownHostException e) {
    System.err.println("Error connecting to host: " + e.getMessage());
    return "-2";
   } catch (IOException ioe) {
    System.err.println("Error sending/receiving from server: " + ioe.getMessage()); // close the socket
   } catch (Exception ea) {
    System.err.println("Unknown exception " + ea.getMessage());
    return "-3";
   }
   return XMLString;
 }
}
 
Thanks,

Thanks Stephan, I didn't realize this was already something that was part of the IPPhones SDK.
 
I just recreated the wheel!...woohoo!
