How to capture input from a swing component.

>> return "secret".equals(JOptionPane.showInputDialog("Enter password"));

You already have this in the logon method. What exactly is the problem?

Disadvantages of doing it that way are that you're hard-coding the correct-password and you're also allowing the user to enter the password in 'visible' format. You should ideally use a JPasswordField and use its getPassword () method to get the password.

Yes, I realized that I will need to use the JPassword and also with setecho???

Problem is I want to replace the logon with my Logon1 app ..
I am not familiar with the getPassword method.

And >>I need to compare a remote methods return value against the entered info..
Do I have to do that within this part?
 
               public void actionPerformed(ActionEvent event)
               {
                    double id = Double.parseDouble(ustidField.getText());
                    double password = Double.parseDouble(passwordField.getText());
               }
          }

          ActionListener listener = new LogonListener();
          logonButton.addActionListener(listener);


the remote method has the signature:
boolean verify(int, String)

So, I will need to change these two:
double id = Double.parseDouble(ustidField.getText());
                    double password = Double.parseDouble(passwordField.getText());

to:
int id = Int.parseInt(ustidField.getText());
String password = (passwordField.getText());  //please provide your alternative

Then I must have some global id and password  that I mast assign to these two....??
And if they match ; return true ???

Please let me know...

Thanks..

>> int id = Int.parseInt(ustidField.getText());

That would be: int id = Integer.parseInt ( ustidField.getText () ) ;

>> I need to compare a remote methods return value against the entered info..
>> Do I have to do that within this part?

It seems you need to compare in the remote method? In that case, you would just read the input in the actionPerformed () method in the way shown above, and then do the comparision in the remote method. It could return a true if they match.

>> Then I must have some global id and password  that I mast assign to these two....??

The remote method could validate it from a data-base or a file where you've saved valid user-IDs and their passwords.

BTW, why is user-ID an 'int'?

I am confused how I can get the id and password and compare it???

I have it as:

class CoursePlanner {
int stid,
String stpwd;
thisclassobject;
     public CoursePlanner(MyObject myserverobject){thisclassobject = myserverobject)
 

void logon() {
 new Logon1();
  }
}

I have to get it from Logon1() in logon() method.>>Logon1 need access to a member variable defined in CoursePlanner>thisclassobject
Logon1() needs this object to execute the verify(id, string) method entered against the  
id and password field...and return true...

void logon() should be defined as boolean,

I am confused..
Let me know if you need clarification..

Thanks.

>> class CoursePlanner {

Is this the remote class? Could you clarify as to what is the remote class and what is the class at the UI?

Maybe instead of having a separate class "Logo1" class to display for user info...
I could have just made a JPanel in the "boolean logon()" method of "CoursePlanner" class.
Then it could be easier to access the thisserver object and execute the remote method "verify(id, password)" entered against the user.?

Please let me know..

Thanks.

The class CoursePlanner is the Client class.
It has a reference to the remote object.
Here is the complete definition (without desired log on).
It was working with the hardcoded "password"
