Using HttpUrlConnection

Question

Hi ,
I'm facing problem in Using HttpUrlConnection. When I submit a request to sun java web server 1.6 . By using the following code I request the server , The server receives the request but can not read the request body that is written on the connection output stream.
my client code :
URL page = new URL(url);
HttpURLConnection sock = (HttpURLConnection) page.openConnection();
sock.setRequestMethod("POST");
sock.setRequestProperty("Content-Length",
"" + Integer.toString(body.getBytes().length));
sock.setUseCaches(false);
sock.setDoOutput(true);
if (body.length() > 0) {
DataOutputStream out = new DataOutputStream(sock.getOutputStream());
out.writeBytes(body);
out.flush();
out.close();
sock.connect();
BufferedReader in = new BufferedReader (new InputStreamReader(sock.getInputStream(),"Cp1256"));
int nHttpResponseCode = sock.getResponseCode();
if(nHttpResponseCode != HttpURLConnection.HTTP_OK){
System.out.println("\tHttp error:" + nHttpResponseCode );
in.close();
return nHttpResponseCode;
//receive reply
in.close();
return nHttpResponseCode;
My server code is :
String params = null;
try {
java.io.InputStream in = request.getInputStream();
byte b[] = new byte[1000]; //in.available()];
in.read(b);
char[] s = new char[b.length];
for (int i = 0; i < b.length; i++) {
if (b[i] == 0)break;
s= (char) b[i];
params = new String(s);
catch (Exception exp) {
exp.printStackTrace();
I tried to submit the request after appending the request body to the url (url like that http://ipadd/webapp/page.jsp?appndedVlaues) and retreived the appended string by calling getQueryString method and It worked well.
Does anybody faced such a problem before?
please help
Thanks

Answer 1

I have done things like this several times with the URLConnection class and it always seem to work. I do not, however, call the
sock.connect();
method. My code seems to work fine without it. First I get the OutputStream and write to it. Then I get the InputStream and read the data from it.
Does the "body" variable in the client code contain any data at all? I don't see it initialized anywhere with data.
I have recently developed a file upload component. It's open source, Apache License and available from our website, www . jenkov . com. It works fine, and that too reads data from the request.getInputStream(). Perhaps you can look at that code and see if you can steal some bits that can make your server code work?
