[SIPForum-discussion] plz help me on sip registration

[maruf syfullah]

 Dear
i am trying sip registration.but response of register request can't be
captured.
i have installed sip server on my local lan.i have created a register user
with user name="maruf" and password="123".
--------sip server address is 195.194.193.7
---------my host's ip is 195.194.193.5.
i am using following very little code:

  SipClientConnection scc = null;
  SipConnectionNotifier scn = null;
  String contact = null;
  String realm=null;
  String username="maruf",password="123";
   try {
       scn = (SipConnectionNotifier) Connector.open("sip:5080");

       contact = new
String("sip:maruf@"+scn.getLocalAddress()+":"+scn.getLocalPort());

       scc = (SipClientConnection) Connector.open("sip:195.194.193.7");

      scc.initRequest("REGISTER", scn);
       scc.setHeader("From", "sip:maruf at 195.194.193.7 ");
       scc.setHeader("To", " sip:maruf at 195.194.193.7");
       scc.setHeader ("Contact", contact);

      scc.send();

      boolean handled = false;
      int scode = 10;

      while(!handled) {
          SipHeader sh;
          // wait max 30 secs for response
          scc.receive(900);
          scode = scc.getStatusCode();

          switch(scode)
          {
              case 401:
                  sh = new SipHeader("WWW-Authenticate",
                     scc.getHeader("WWW-Authenticate"));
                  realm = sh.getParameter ("realm");

                  scc.setCredentials("maruf", "123", realm);
                  break;

              case 407:
                  sh = new SipHeader("Proxy-Authenticate",
                     scc.getHeader("Proxy-Authenticate"));
                  realm = sh.getParameter("realm");
                  // here for example, prompt user for password for this
realm
                  // set credentials to initiate re-REGISTER
                  scc.setCredentials ("maruf", "123", realm);
                  break;

              case 200:
                  // handle OK response
                  handled = true;
                  break;
              default:
                  System.out.println("default" );
                  // handle other responses
                 // handled = true;
          }
      }/////////////////
     // scc.close();
  } catch(Exception ex) {
      // handle Exceptions
  }

using packet sniffer i have seen that response from server comes to my host
but my program cant capture  it.i have tried using netbeans and wireless
toolkit.

will u plz tell me where is the problem?

Best Regards
Maruf
