      What do you mean by "manage this application"? Does it misbehave or doesn't it work?

          dear Jos,
          thanks for reply..
          I'm in a big problem , that I can't solve it
          my IT director ask me to build an application to get data from a server.
          so I make a socket connection with this server.
          I send first the authentication to the server, so server send ALLOW message.
          then I start to send request and it response with a response message.
          the PROBLEM is that I can't get all the response message.
          I make Thread.sleep(40 00) between sending the request and the response...
          but no way
          I make Thread.sleep(60 00) or even Thread.sleep(10 000) but no way
          its usually not all the data
          so how can I read all the data from the socket response

          waiting ur help

              Does that server use some sort of protocol? It can't just send a bunch of bytes
              where the client has to automagically 'guess' how many bytes it is supposed to
              receive.

              kind regards,

              Jos

                  The answer for your question is (yes)., server sends a bunch of bytes

                  is socketchannel solve this problem ??
                  socketchannel is non-blocking..

                  waiting




                  can I write to u directly ?? to ur eamil

                      If your server side is so rigid (and stupid) SocketChannels don't buy you much
                      either. All you can do assume that everything has been read after a little time
                      span had passed and nothing was read. You an use separate Threads for that,
                      or if you want you can use SocketChannels.

                      Please don't email me; this problem might be interesting to others as well.
