<Stack>org.xml.sax.SAXParseException: Content is not allowed in prolog.
Below Code i am using for sending data over Post http (rest service).
below is code for that.
public String postHttp(String data, String urlString, String acceptString, String contentTypeString) throws Exception {
HttpURLConnection conn = null;
PrintWriter writer = null;
BufferedReader reader = null;
if (log.isVerboseEnabled()) {
log.verbose("Posting data over HTTP.URL: " + urlString + " Data posted: data: " + data);
}
String output = null;
URL url = new URL(urlString);
if (log.isDebugEnabled())
log.debug("The Url is --->" + url);
try {
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
// This change is made to support XML in Http POST
if (!YFCObject.isNull(acceptString) && !YFCObject.isNull(contentTypeString)) {
conn.setRequestProperty("Accept",acceptString);
conn.setRequestProperty("Content-Type",contentTypeString );
}
conn.connect();
writer = new PrintWriter(conn.getOutputStream());
writer.println(data);
writer.flush();
// Get the response
responseCode = conn.getResponseCode();
responseMessage = conn.getResponseMessage();
// TODO: Need to validate. Should this be only for 200?
if (responseCode==200) {
log.verbose("Posting data over HTTP completed.URL: " + urlString + " Response: " + responseMessage);
System.out.println("Posting data over HTTP completed.URL: "+ urlString + " Response Status: " + responseCode);
}
else if (responseCode < 400) {
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
output = getResponseData(reader);
}
else if (responseCode >= 400){
reader = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
output = getHTTPStatusErrorOutput(responseCode, responseMessage);
}
if (log.isVerboseEnabled()) {
log.verbose("Posting data over HTTP completed.URL: " + urlString + " Response data: " + output);
}
} catch (MalformedURLException mfue) {
output = getErrorOutput(mfue);
} catch (UnknownHostException uhex) {
output = getErrorOutput(uhex);
} catch (Exception ex) {
output = getErrorOutput(ex);
} finally {
if (conn != null) {
conn.disconnect();
if (writer != null)
writer.close();
if (reader != null)
reader.close();
}
}
return output;
}
Could you tell is their any mistake in that way.some time its is hang on this point conn.setDoOutput(true); web.postHttp(doc,url,"application/xml","application/xml"); In rest side we are unable to getting any messages. Any help would be appreciated.
