I am having a problem with implementing the readLine() method of the
BufferedReader.  I have an IP socket server written in Delphi C/S 3.0
running on NT and want to send/receive a string of text to/from this ip
server with a java client application (not an applet).  This java
application will eventually be a servlet.  But first I need to get some
of the basics of Java based IP programming under control.

The problem is that the readLine() quits once a carriage return and/or a
line feed is 'hit'.  So I decided to create a for loop that will execute
100 times until an exception is raised which will force an exit.  (BAD
CODE)  Don't like counting on the exception and I never know if 100
executions of readLine() will be enough.  The server application
(Delphi/NT) will close the connection once the data is sent back if this
helps...

Any other (GOOD CODE) ways of implementing this?  For the example I am
using port 80 on yahoo's web server and sending a request for the
default page of the server, but my needs are not URL based.  I need to
send and receive multiple strings to and from an open ip socket on a
server (non standard ports).

Thanks!

      try {
        for(int i = 0; i < 100; i++)
          System.out.println(in.readLine()); }
      catch(Exception e) { } }
    catch(Exception e){
      e.printStackTrace(); } } }
