Thread: Reading ip and port from xml file

Hi,
I am trying to read the ip and port number from xml file and using its value in my code. But I am facing problem to connect to server through ip and port number which I get from xml file. However when I hard code the value itts working fine.
Please let me know what could be the possible reason for this. Thanks!!!!!!

public class Client {
 
    /**
     * @param args the command line arguments
     */
 
    public static connection conn;
    public static void main(String[] args) throws Exception{
        // TODO code application logic here
 
        System.out.println("Client Signing In");
 
        System.out.println("Client Connection Establish");
        Global.initial();
        System.out.println(Global.ip);
        System.out.println(Global.port);
        //conn = new connection("127.0.0.1",9081);
        conn = new connection(Global.ip.trim(),Global.port);
