Issue with a Validation Class

Question

Hello all,
I have the following validating class that is supposed to check the usernames and passwords held in a file against what the user has typed into a form;
package bus;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import org.springframework.validation.Errors;
import org.springframework.validation.Validator;
import bus.Credentials;
public class LogonValidator implements Validator {
    public boolean supports(Class clazz) {
        return clazz.equals(Credentials.class);
    public void validate(Object obj, Errors errors) {
         Credentials credentials = (Credentials) obj;
         String usernameCompare = credentials.getUsername();
         String passwordCompare = credentials.getPassword();
         String username;
          String password;
          String[] data;
         try {
            BufferedReader in = new BufferedReader(new FileReader("C:/Documents and Settings/Jaz/workspace/OBS/war/LoginInfo.txt"));
            String inLine = null;
            while ((inLine = in.readLine()) != null) {
                 data = inLine.split(",");
                 username = data[0];
                 password = data[1];
               if (((username.toString()).equals(usernameCompare))== false){
                     errors.rejectValue("username", "error.login.invalid-user",
                               null, "Value required.");
               else{
               if (((password.toString()).equals(passwordCompare)) == false){
                          errors.rejectValue("password", "error.login.invalid-pass",
                                    null, "Incorrect Password.");     
           in.close();
      }catch (IOException e){
}the file the class is to read from (LogonInfo.txt) intially contained only;
guest,guestand the app worked perfectly fine. However when more entries were added as such;
guest,guest
vip,vip
someone,someone
nobody,nobodythe form did not validate anything anymore. When I enter a valid username and password that is found in the txt file it simply says value required. Even if I use the initial entries of guest. Im completely lost with this one. Can anyone help?
Thank You

Thank you very much for your help. I have amended the code as such;
while ((inLine = in.readLine()) != null) {
                 data = inLine.split(",");
                 username = data[0];
                 password = data[1];
               if (username.equals(usernameCompare) && password.equals(passwordCompare)) {
                   break;
            if (username.equals(usernameCompare)== false && password.equals(passwordCompare)){
                         errors.rejectValue("username", "error.login.invalid-user",
                                   null, "Value required.");
             else{
             if (password.equals(passwordCompare) == false && username.equals(usernameCompare)){
                         errors.rejectValue("password", "error.login.invalid-pass",
                                   null, "Incorrect Password.");
           } I thought this would have worked, however it validates the username and password even if both are incorrect. What I would have expected it to do is to validate only if both username and password were correct.
Also if the username was correct and password incorrect display the appropriate error message. Again if the password was incorrect and the username correct display the error message.
I dont understand why this is not working.
