Hi,

I got the solution myself.

  1. Register gateway / transport like msn, gtalk,yahoo as shown in the avobe code
  2. Next you have to add that transport to your roster means gtalk.domain_name, msn.domain_name etc…

public void XMPPAddRosterEntry(Roster roster, String userIDWithDomainName, String userNickName, String Reserved)
{
try
{
roster.createEntry(userIDWithDomainName, userNickName, null);
}
catch(Exception e)
{
System.out.println("ADD_ROSTER_ERROR: "+ e);
}
}

XMPPAddRosterEntry(roster, “gtalk.yourdomain”, “MyGtalk”,null);

avobe code works for me.

But is there a way to check that roster is properly added to my roster?

is there a way that transport / gateway registration is successfull?

is there a way to know whether registering a new user is done correctly?

Thanks,

Samba
