stopped working properly. The codee hasn't changed but my web page its on
and my dns settings have mind you i can still see the host its trying to
connect from a wb page ping etc. Now when i run it locally i get
java.security.AccessControlException: access denied

I assumed that this was because i was running it locally. so i copied it and
the web page to my web site and i tried from there. I get

try

socket.setSoTimeout(3000);
socket.connect(new InetSocketAddress("members.g7wap.me.uk", 80),3000 );
}
catch(AccessControlException u)

retVal=true;
}
// C L O S E
try
{
socket.close();
}
catch(IOException u)
{
}
return retVal;
}
}
now remember this applet is in a signed jar and it worked for some time so
what's going wrong?
Thanks
