Java Forum / General / May 2007How to stop a socket when it is connecting to remote?
in one thread it's: Global.socket_control = new Socket(InetAddress.getByName("192.168.1.22"), 1234); when the IP:192.168.1.22 does not exist, it will take so much time to wait before throw a "time out exception" how can I stop this waiting in another thread? I have try "Global.socket_control.close()" but it doesn't work because Global.socket_control is null Thank you very much in advance > in one thread it's: > Global.socket_control = new [quoted text clipped - 8 lines] > > Thank you very much in advance Use connect() timeout instead of using a full constructor. > in one thread it's: > Global.socket_control = new [quoted text clipped - 8 lines] > > Thank you very much in advance Use no-arg Socket constructor and connect() with explicit timeout arg. thank you very much but is it other way to stop it? I mean long time "time out" maybe useful when it's a long distance(is it?) > but is it other way to stop it? > I mean long time "time out" maybe useful when it's a long distance(is > it?) So if you don't want to use a timeout how are you going to decide when you want to stop it? >> but is it other way to stop it? >> I mean long time "time out" maybe useful when it's a long distance(is >> it?) > > So if you don't want to use a timeout how are you going to decide when > you want to stop it? Maybe the user presses the Cancel button? (I.e., some non-timer external event...) > >> but is it other way to stop it? > >> I mean long time "time out" maybe useful when it's a long distance(is [quoted text clipped - 5 lines] > Maybe the user presses the Cancel button? (I.e., some non-timer > external event...) Yes, I want to provide a "Cancel" button to stop waiting when it's trying to connect to remote. how can I do with this "Cancel" button? > Yes, I want to provide a "Cancel" button to stop waiting when it's > trying to connect to remote. > how can I do with this "Cancel" button? Try socket = new Socket(); socket.connect(...); That way there is an existing socket object for the cancel button to close, whereupon 'Any thread currently blocked in an I/O operation upon this socket will throw a SocketException.' > Try > > socket = new Socket(); > socket.connect(...); Thank you very much It works! : ) Free MagazinesGet these publications absolutely FREE for up to 12 months.
