XML HTTP Post

Hi

I am new to using xml with HTTP posting and would like some advice. I need to read an xml file and post the xml data via http to a webserver.

The problem is the webserver returns that no data has been sent. What I have got is as follows:

1. A text file containing the xml data. I read from the text file as follows:

FileInputStream fis = new FileInputStream("c:/test.txt");
        int x= fis.available();
        byte b[]= new byte[x];
        fis.read(b);
        String xmldata = new String(b);

2. The I do the HTTP post as follows

String hostname = "wsisf29";
      int port = 7001;
      InetAddress addr = InetAddress.getByName(hostname);
      Socket sock = new Socket(addr, port);
        System.out.println("Connected");
      //Send header
      String path = "/aws/core/online";
      BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream(),"UTF-8"));

      System.out.println("Start Writing");
     wr.write("POST " + path + " HTTP/1.0\r\n");
     wr.write("Host: www.pascalbotte.be\r\n");
      wr.write("Content-Length: " + xmldata.length() + "\r\n");
      wr.write("Content-Type: text/xml; charset=\"utf-8\"\r\n");
      wr.write("\r\n");
        System.out.println(xmldata.length());
               // System.out.println(xmldata.);
      //Send data
      wr.write(xmldata);

      wr.flush();

If I do a sout on xml data it does return the whole set of xml text. However the server returns data sent invalid. Do i need to post the xml data line by line?

Any advice appreciated.

Marnus

Hello,

If not already done, change the Host in your mime header.

Hope this help,

I have done sth similar.
Maybe it will help.

Code:

String data = "HERE IS XML FILE";
String path = "/servlet/xml";
osw.write("POST "+path+" HTTP/1.0\r\n");
osw.write("Content-Length: "+data.length()+"\r\n");
osw.write("Content-Type: application/x-www-form-urlencoded\r\n");
osw.write("Connection: keep-alive\r\n");
osw.write("\r\n");
osw.write(data);
osw.flush();

And it works fine.
BTW. for sure you dont need to POST xml file line by line.
