Http client Post xml file in java

Question

I need to send a xml file to the following link\

    http://14.140.66.142:80/MSMQ/private$/votes

This is my code.

   URL url = new URL("http://14.140.66.142:80/MSMQ/private$/votes");
    URLConnection con = url.openConnection();
    String document = "C:\\Documents and Settings\\Nagra\\My Documents\\Responseserver\\workingVoting\\VoteSubmitter\\Body.xml";

    FileReader fr = new FileReader(document);
    // specify that we will send output and accept input
    con.setDoInput(true);
    con.setDoOutput(true);
    char[] buffer = new char[1024*10];

    int b_read = 0;

    if ((b_read = fr.read(buffer)) != -1)

    {
        con.setRequestHeader ( "Content-Type", "text/xml" );
        con.setRequestProperty("SOAPAction","MSMQMessage");
        con.setRequestProperty("Proxy-Accept","NonInteractiveClient" );
        con.setRequestProperty("CONNECTION", "close");
        con.setRequestProperty("CACHE-CONTROL", "no-cache");
        con.setRequestProperty("USER-AGENT", "OpenTV-iAdsResponder_1_0");
        OutputStreamWriter writer = new OutputStreamWriter( con.getOutputStream() );
        writer.write(buffer, 0, b_read);
        PrintWriter pw = new PrintWriter(con.getOutputStream());
        pw.write(buffer, 0, b_read);
       pw.close();
        System.out.println("written");


  }
  catch( Throwable t )
{
    t.printStackTrace( System.out );
}

  }
  }

I don't Know whether it is right code.If i run this code I am not able to receive the xml file on the server side.Can anyone help me where i gone wrong in my code.

Solution

Below is a sample POST operation:

URL url = new URL("http://14.140.66.142:80/MSMQ/private$/votes");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");

OutputStream os = connection.getOutputStream();

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
FileReader fileReader = new FileReader("C:\\Documents and Settings\\Nagra\\My Documents\\Responseserver\\workingVoting\\VoteSubmitter\\Body.xml");
StreamSource source = new StreamSource(fileReader);
StreamResult result = new StreamResult(os);
transformer.transform(source, result);

os.flush();
connection.getResponseCode();
connection.disconnect();

This is the error which i Got while running your code. org.xml.sax.SAXParseException: Content is not allowed in prolog. at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser‌​.parse(AbstractSAXPa‌​rser.java:1231) at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl‌​.transformIdentity(T‌​ransformerImpl.java:‌​609) at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl‌​.transform(Transform‌​erImpl.java:707) at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl‌​.transform(Transform‌​erImpl.java:313) at hhtprequest.main(hhtprequest.java:52)

@bharathi - Can you try the transform outside the HTTP operation (set the output to System.out)? This code has been successful for others:stackoverflow.com/questions/6665769/…
