swing - In java socket programming, is it necessary to run server program first before client program? -

i building remote desktop viewer app using swing. when run server first , client, app working fine.

but when run client first , server, client gives exceptions there no listening server.

what should if run client first , server connection should successful , client should not give exceptions?

thanks.

connectexception thrown when client tries connect server not started. have retry logic using

try{     socket.connect(..)  }catch(connectexception ex) {  }  

within loop. delay can added between retry free cpu.
