Hi All,
I am doing a HTTP POST on a servlet running on my local box. For this, I
am opening a socket on port 80 and sending the data.
When I call getReader() on HttpServletRequest object, I cannot find any
data. Instead of Calling getReader(), if I call getParameter() or
getParameterMap() on HttpServletRequest object, I can retrieve the data
which has been posted
This works well on Linux 4 with apache version 2.0 and tomcat version
4.X and jk2 i.e. getReader returns data.
The issue is seen on Linux 5 with apache version 2.2.3 and same tomcat
version 4.X and mod_jk1.2.27.
Any clues as to what is going wrong?
Using tcpdump, I have seen the request - It looks as expected.
------------------------------------------------------------------------
----------------------
POST /servlet/Help HTTP/1.0
Content-Length: 17
Content-Type: application/x-www-form-urlencoded
Want to send this
------------------------------------------------------------------------

SERVER CODE:
--------------------
getReader() on HttpServletRequest object returns me BufferedReader
object.
If I call read() on buffer, I get -1. If I call readLine() on buffer, I
get NULL.
This is how I am calling in my servlet:
java.io.BufferedReader _buffer = req.getReader();
System.out.println("****Is Buffer object ready " +
_buffer.ready());
System.out.println("****Is Buffer object char: " +
_buffer.read());
System.out.println("****Is Buffer object line: " +
_buffer.readLine());
Instead of Calling getReader(), if I call getParameter() or
getParameterMap() on HttpServletRequest object, I can retrieve the data
which has been posted.
CLIENT CODE:
-----------------
// Construct data
String data = "Sending simple data";
// Create a socket to the host
String hostname = "127.0.0.1";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket socket = new Socket(addr, port);
// Send header
String path = "/servlet/Help";
BufferedWriter wr = new BufferedWriter(new
OutputStreamWriter(socket.getOutputStream(), "UTF8"));
wr.write("POST "+path+" HTTP/1.0\r\n");
wr.write("Content-Length: "+data.length()+"\r\n");
wr.write("Content-Type:
application/x-www-form-urlencoded\r\n");
wr.write("\r\n");
// Send data
wr.write(data);
wr.flush();
// Get response
BufferedReader rd = new BufferedReader(new
InputStreamReader(socket.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
// Process line...
System.out.println(line);
}
wr.close();
rd.close();
