I think the codes work for the server with no restrictions of range request. now i have to look what to do for the server with it.

Yes is the school project . maybe because we will know many things on HTTP header with this

I do like to use this so. but I do think is the subclass of URLconnection which is forbidden for our project. Any other suggestions please

I don't think so because if what I am saying is true there is no Accept-Range in HTTP header response. Otherwise does this way work only with the server which accept this request

Her is the output for the header

Connection: close

I want to download in parallel the parts of file. I read that some articles say that. I can use HTTP/1.1 to specify the range i want for each part downloaded at each tcp connection, so I wonder if the following codes can help me to establish a connection while specifying the range. Notice when I excute the codes below nothngi change to the ouput. it seems the following part "Range: bytes=0-500\r\n" doesn't change anything.

Any Help I will I appreciate.


URL url = null;

url = new URL("http://twitter.com/statuses/user_timeline/13507732.atom");





try {

Socket socket = new Socket(url.getHost(), 80);
OutputStream os = socket.getOutputStream();
PrintWriter out = new PrintWriter(os);


String query = url.getQuery();
query = (query == null) ? "" : '?' + query;
String hostname = url.getHost();

// send an HTTP request to the web server
out.write("GET " + url.getPath() + query + " HTTP/1.1\r\n" + // The request
"Host: " + hostname + "\r\n" + // Required in HTTP 1.1
"Range: bytes=0-500\r\n" + // The request
"Connection: close\r\n");
out.println();
out.flush();




// read the response
InputStream inputStream =
socket.getInputStream();
InputStreamReader inputStreamReader =
new InputStreamReader(inputStream);
BufferedReader in =
new BufferedReader(inputStreamReader);


String line;



while ((line = in.readLine()) != null) {



System.out.println(line);



}
// Close everything
out.close();
in.close();
socket.close();


} catch (IOException e) {

System.err.println("Problems talking to " +"twitter user" );
e.printStackTrace();
}
}

}

In the project I have to submit this Friday in evening. The professor demand us not use it becaause with is very easy fo example to remove http header

I want to download file in parts using http range header. I want to make the connection on the server without use URLconnection.
Any help or sample codes for how I can begin, I will appreciate. Thank you.

Thank you Paul. really I made mistakes I should add this getDocumentElement() to get all child nodes. now I still have another question how to get the text means the contents of each nodes. here are the ouputs.


Root Node Name: feed
#text
title
#text
id
#text
link
#text

#text

#text

Here is the xml inputstream that I received from this URL "http://twitter.com/statuses/user_timeline/13507732.atom".

The codes suppose to print out the Root no names and his child node name like <title></title>. And then after I will change or adapt the codes to find the content of each nodes.



Thank you

No I didn't. It seems that I only read the begining and the rest fo the file is empty. which has non sens . many suggestions I got , I dealt with but no change.

Hello Paul. the output I get is only the the root node name. but if you look well . I also make this

NodeList children = document.getChildNodes();
for (int i = 0; i < children.getLength(); i++)
{
String child = children.item(i).getNodeName();

System.out.println(child);

To print the childnode list.

Thank you

Hello william. I know that httpurlconnection can do this but the project I have to submit this Friday. The professor demand not use urlconnection because with it everything is done like remove http header. If you see any way I can deal with this thank you for your help.

I am new in java network and I want to parse xml inputstream but when I' m running this codes to find the Nodechild nothing in output.

Here are my codes. any help I will appreciate, Thank U. I notice that , I don't want to use some classes that remove HTTP header in process.
