This is the code I use to do what you're trying to do, I'm not sure
about the usage of DataOutputStream as that's the main difference I
see in terms of setting up my socket and your setup.
private boolean connect(String ip, String port)
{
try
{
InetAddress serverAddr = InetAddress.getByName(ip);
int iport = Integer.parseInt(port);
if (iport < 0)
{
throw (new NumberFormatException());
}
if (defaultip.equals(""))
{
throw (new UnknownHostException());
}
connection = new Socket(serverAddr, iport);
// initialize the output stream to send data to server
out = connection.getOutputStream();
;
return true;
}
catch (Exception e)
{
return false;
}
