File I/O problems using a Properties file

Question

Hi,
I am having troubles reading in a properties file. The file looks like this:
aname=apassword:word2
bname=bpassword:word
...etc
The code I have this far is:
import java.util.*;
import java.io.*;
public class LoginH
public static void main(String[] args)
String logon, pswd;
//String login = null;
//String password = null;
//String nick = null;
int msg = 0;
System.out.print ("Login: ");
logon = MyInput.readString();
System.out.print ("Password: ");
pswd = MyInput.readString();
Properties settings = new Properties();
try
FileInputStream sf
= new FileInputStream("LogonH.ini");
settings.load(sf);
catch (FileNotFoundException e) {}
catch (IOException e) {}
// public void whitespaceChars(58,58)
StringTokenizer st = new StringTokenizer(settings.getProperty(logon));
String password = st.nextToken();
String nick = st.nextToken();
System.out.print (password + nick);
** It works fine if i replace the colon in my properties file with a blank space, However i need to use a colon. I tried to set whitespaceChar to allow this but I can not seem to get it to work. Let me know if you have any ideas. Thanks in advanced.

Thanks. I just got done doing something to that nature however now my problem is if the key field is not in my properties file my program crashes. I need to print out to the console "sorry" if my user name which is my key is not in the properties file. Here is my code if anyone can help me out:
import java.util.*;
import java.io.*;
public class LoginH
public static void main(String[] args)
//******** Declare Variables *********************
String userlogin;
String userpaswd;
String login = null;
String paswd = null;
String nicknm = null;
int match=0;
String delim = ":";
//******** Get username and password **************
System.out.print ("Login: ");
userlogin = MyInput.readString();
System.out.print ("Password: ");
userpaswd = MyInput.readString();
Properties settings = new Properties();
try
FileInputStream sf = new FileInputStream("LogonH.ini");
settings.load(sf);
catch (FileNotFoundException e) {}
catch (IOException e) {}
StringTokenizer st = new
StringTokenizer(settings.getProperty(userlogin),delim);
paswd = st.nextToken();
nicknm = st.nextToken();
if(userpaswd.equals(paswd))
System.out.println("Ok " + nicknm);
match = 2;
else
System.out.println("Sorry " + nicknm);
match = 1;
if (match == 0) System.out.println("Sorry");
}
