Dear all I'm having difficulty in reading from a java socket in perl.

java code:**SERVER**

int port=5551;
             ServerSocket ss=new ServerSocket(port);
 //            System.out.println("Waiting for lient");
             Socket s=ss.accept();
   //          System.out.println("Waiting for clienttttt");
             
             BufferedReader br=new BufferedReader(new InputStreamReade
+r(s.getInputStream()));
             DataOutputStream pw = new DataOutputStream(s.getOutputStr
+eam());
             //PrintWriter pw=new PrintWriter(new OutputStreamWriter(s
+.getOutputStream())) ;
             String str=br.readLine();
             int n=Integer.parseInt(str);
             int i;
             long f=1;
             System.out.println("Number sent by client: " + n);
             for(i = 2; i <= n; i++)
                 f = f * i;
             
             System.out.println("Number sent to client: " + f +n);
             
             pw.writeLong(f);


perl code ***CLIENT****
 use threads::shared;
      2 use IO::Socket;
      3 use IO::Select; #[/RP001]
      4 use IO::Handle;
      5 chomp(my $hostname = `hostname`);
      6
      7 my $dmx_sock = new IO::Socket::INET(
      8               PeerAddr => $hostname,
      9                           PeerPort => 5551,
     10                                       Proto => 'tcp',
     11                                               );
     12 $dmx_sock or print "err";
     13 print $dmx_sock "2";
     14 sleep(5);
     15 my $buf;
     16 read($dmx_sock, $buf,1);
     17
     18 my ($tag,$code,$len) = unpack 'L', $buf;
     19 print "\$tag = '$tag'\n";
     20 print "\$code = '$code'\n";
     21 print "\$len = '$len'\n";
     22 read($socket, $buf, $len);
     23 print "\$buf = '$buf'";
     24
     25
     26
     27 #$dmx_sock->close;
     28 print "<<<$buf>>>>";
