java - Ubuntu - UnknownHostException when connecting to a PC, using a Socket in an Ad Hoc network -

i have created filesystemlistener listens files in folder , sends them specified ip address. has been tested standard wireless network getting unkownhostexception when running on ad hoc network.

i not sure if should ask on superuser, or here, not sure if issue code or ubuntu.

i can ping other pc on wireless network keep getting above exception when connecting through java.

not sure if helps here basic ssce can think of:

import java.net.socket;  public class clienttester {    public static void main(string[] args) {         socket s  = new socket("192.168.0.1", 4440);    } } 

anyone come across before, wanted see if java issue before cross posted in superuser.

thanks!

to compile correctly, unknownhostexception "must caught or declared thrown."

for example:

import java.io.ioexception; import java.net.socket; import java.net.unknownhostexception;  public class clienttester {      public static void main(string[] args)         throws unknownhostexception, ioexception {         socket s  = new socket("192.168.0.1", 4440);    } 

}
