    System.out.println(name + " exiting.");
}the system dose not give error but it dose not send sms either i found out that it was cus of the url and the gateway that iw as using so i found a new gatway which is in malaysia ( thats where im implementing my system) and this is how the new source code looks like for the URL
  URL u = new URL("http://www.bulksms2u.com/websmsapi/ISendSMS.aspx?username=xxxxx" +
                             "&password=xxxxx&message" + name + ":Unable to Lookup..." + "&mobile="
                             + phonenumbers.get(i) + "&sender=IP-Admin&type=1");
                    URLConnection uc = u.openConnection();i have replaced it with the old one which it was
URL u = new URL("https://myaccount.dialnow.com/clx/sendsms.php?username= xxxxxxx&#8203; &#8203;&" +
                                "password= xxxxxxx&#8203;&from= xxxxxxx&#8203;&to=" +
                                phonenumbers.get(i) + "&text="
                                + name + ":TimeOut...");this new url works i have tried it using direct url into a explorer and the sms has been sent but this way it dose not work
dose any one have any clue what should i do to get respond for sending this sms?

i tried applying it directly into browser did not work, I thought you said it did work. The reason is that browser a lot of the time will apply URL encoding on things manually entered.
and about ( URL encode the parameter values before concatenating them into the URL. ) i dont get what u mean can you be specific?Check java.net.URLEncoder Only specific characters are allowed in a URL, other characters need to be encoded/escaped using a process called URL encoding
