URLConnection.getInputStream() not reading the full HTML

Question

I need code to read a html file after posting a request. The code is as follows:
URLConnection connection = url.openConnection();
connection.setDoInput( true );
connection.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
if(in.equals(null)){
throw new IOException();
while((inputLine = in.readLine()) != null){
System.out.println("line is: " + inputLine);
Sometimes it works fine. Sometimes it can not read full content.(may be the low network). but i view the source in my browser, I can find it just fine.
Any ideas? Has anyone encountered this kind of problem?

Answer 1

my code is same for reading input from a servlet, but it sometimes get and inputstream, sometimes, don't, it always can not read the second one. mine code is inside applet and chat with other applet thourgh a servlet. The server side does write message out.
Any insight how to debug this, I am totally out!!
