I am trying to send a xml file to an URL, and it should respond me with an other xml file. I am trying to do this with the code below :
URL url = new URL("url.example.com");
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("path\\test.xml");
StreamSource source = new StreamSource(fileReader);
StreamResult result = new StreamResult(os);
transformer.transform(source, result);
os.flush();
connection.getResponseCode();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
try {
Document docxml = db.parse(connection.getInputStream());
System.out.println("Input Stream : " + docxml.toString());
}catch(Exception e) {
System.out.println("Input Stream : " + e.getMessage());
}
connection.disconnect();
When i run the code i'm getting this error :
Input Stream : Server returned HTTP response code: 500 for URL
I am sure the url and the file are good, is there any error in my code and the way i send my http request? Or does the error comes from the server or anything? If you have any idea or suggestion about my code or about what i could do to debug and know where the problem come from, thanks.
