You could run a timer that checks Socket.isConnected(), and if it returns false, then retry the connection.

That is all possible but imagine the server keeps a lot of state. When the server notices a lost connection it might free its resources (state). Simply establishing a new connection won't do it then. I am wondering why the connection might be 'unexpectedly' get lost. Bad cables? That'd be a job for an electrician ...

kind regards,

Jos

well, my application does not run on LAN, but it will run on WAN, so I am just concerning when the WAN connection down.. then the client socket should know then they should keep trying to reconnect to the server

any idea or comment?

Ignoring all the state stuff I mentioned: what Zack said.
