Change the initial focus to "message" in JOptionPane.showOptionDialog?

JPanel panel = new JPanel (false);
JTextArea txtArea = new JTextArea (msg, 2, 60);
JScrollPane sPane = new JScrollPane (txtArea);
panel.add (sPane);
int button = JOptionPane.showOptionDialog (frame, panel, titleStr, optionType, JOptionPane.PLAIN_MESSAGE, null, null, null);
Is there a way to make txtArea to have the initial focus?
Thanks,

Simple JOptionPane.showOptionDialog() question

Could you please help me:
Here's a piece of code:
JPasswordField field = new JPasswordField();
int choice = JOptionPane.showOptionDialog(null, field, "Enter password:", 0,
JOptionPane.QUESTION_MESSAGE, null,
new String[] {"ОК", "Cancel"}
, null);
How to make an enter-key-press on JPasswordField to be equivalent to pressing OK key?? If it's possible or i should use bigger constructions (like private class PasswordAskClass extends JDialog) ???
Thanks in advance for your replies.

The problem is that you don't have a reference to the OK button.
1) use a JDialog like you suggest.
2) Create the buttons yourself, and pass them into JOptionPane as arguments.
Then you'll be able to add a KeyMap to your JPasswordField that when ENTER is pressed, it sends an action event to your OK button.

A question about JOptionPane.showOptionDialog()?

one problem confused me.
import javax.swing.*;

     int n;
     String title;
     Object[] message = new Object[3];
     Object[] obj = new Object[2];
     message[0] = "Name ";
     message[1] = "Age";

i run the java compiler in command line.
c:\proj1>javac Test.java
c:\proj1>java Test
Having done the program, i found that command line didnot return to "c:\proj1>"
only after "Ctrl-c" can that return back to the "c:\proj1". i didnot meet this problem when i run other java projects.
what's the problem?
thanks!

Implement a call to System.exit(0) at the point you want the programm to close.
(Depending on the return code of your option dialog)

JOptionPane.showInputDialog Help!!!!

Hello,
I'm using JOptionPane.showInputDialog(Component parentComponent,
Object message,
String title,
int messageType,
Icon icon,
Object[] selectionValues,
Object initialSelectionValue ).
which prompts the user to add some text and the same will be stored for later retrieval.
In this case, JOptionPane pops up with a label, textfield,OK & Cancel buttons.
Default focus is given to to the TextField.
Is there anyway to get access to the TextField via code ?
For example, if the user types "Hello World" in the given TextField, then I need to get the Text entered in
the TextField in the following manner.
String myStr = myJOptionPaneTextField().getText();
System.out.println("Entered Text is "+ myStr);
How can I Achieve the same ?
Thanks in advance
Regards
vargav

Why? At what point do you know you should manipulate the text? Usually, it would be when the user clicks OK, at which point it doesn't matter because the dialog is dismissed. So what kind of operations do you expect to be able to do?
Aside from that, I'm not sure how to get the text field in the option pane, per se... It can be gotten by digging thru the pane's components til you find a text field. But you'd need to do that in a separate thread. So it's not really feasible to do that.... There is an alternative:
The message is an object, and it can be an array of objects, which will all be added, and thus can include a message string and a text field...
JTextField myfield = new JTextField();
Object[] obj = new Object[2];
obj[0] = "Enter some text here:";
obj[1] = myfield;
if(JOptionPane.showOptionDialog(obj, "Enter Text", JOptionPane.OK_CANCEL_OPTION) == JOptionPane.OK_OPTION) {
String value = myfield.getText();
}Then you can do whatever you want with the text field... but the same problem is there, you have lost the dialog before you can do anything.

JOptionPane.showOptionDialog(..) -problem

Hi!
I'm trying to ask the size of area of game with OptionDialog. Then this
code should open the game frame. But the OptionDialog doesn't react
to clicking. (doesn't close). Could you find the errorpoint?
I have trying to find it many days.
Could it be probably so that the main-method can't open frame after frame (first optionDialog then gameframe)?
Gameframe opens when I test it to replace getGameAreaSize()-method simply with:
public int getGameAreaSize() {
return 10;
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
public class BattleShipGame {
     private int gameAreaSize;
     private Gameframe gameFrame;
     public Gameframe getGameframe() {
        if (gameFrame == null) {
             gameFrame = new Gameframe();
             gameFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        return gameFrame;
     public int getGameAreaSize() {
       Object[] options = {"10 x 10",
                           "12 x 12",
                           "14 x 14"};
       int n = JOptionPane.showOptionDialog(new Frame(),
       "Choose the area of the game: ",
       "question about area",
        JOptionPane.YES_NO_CANCEL_OPTION,
        JOptionPane.QUESTION_MESSAGE,
        null,
        options,
        options[2]);
        if (n==0) return (gameAreaSize = 10);
        if (n==1) return (gameAreaSize = 12);
        if (n==2) return (gameAreaSize = 14);
        else return (gameAreaSize = 0);
     public static void main(String[] args) {
        BattleShipGame bsg = new BattleShipGame();
        int size = bsg.getGameAreaSize();
        Gameframe gameframe = bsg.getGameframe();
        gameframe.setVisible(true);

int n = JOptionPane.showOptionDialog(new Frame(),
should be :
int n = JOptionPane.showOptionDialog(this,
Because when you start a new frame that hasn't got the focus and you let that frame pop the optionpane the mouse listener andsoon isn't listening to the optionpane.

Cannot Import javax.swing.JOptionPane Please HELP!!!

Please help, I don't know what the problem could be....

Swing was not part of any JDK's earlier than 1.2. Swing (or anything with a J in front of it, ie. JFrame, JOptionPane, etc...) was probably the most dramatic (if not largest) modification/addition to the Java language, that's why versions later than, and including, 1.2 are known as "Java 2".

JOptionPane Help Needed

I basically have two problems with JOptionPane that I've searched for answers yet I haven't found an applicable answer for my application. Here they are:
1) How can I get a JPasswordField in a JOptionPane to be given focus when the JOptionPane is displayed?
2) How can I get the default key mappings for JOptionPane not to work or atleast make it where when a user hits "Enter", it activates the button that has current focus? I have a problem with highlighting "Cancel" and hitting "Enter".
Here is my code being used for the JOptionPane:
String pwd = "";
int tries = 0;
JPasswordField txt = new JPasswordField(10);
JLabel lbl = new JLabel("Enter Password :");
JLabel lbl1 = new JLabel("Invalid Password. Please try again:");
JPanel pan = new JPanel(new GridLayout(2,1));
int retval;
while(tries < 3 && !valid)
     if(tries > 0)
          pan.remove(lbl);
          pan.remove(txt);
          pan.add(lbl1);
          pan.add(txt);
          txt.setText("");
     else
          pan.add(lbl);
          pan.add(txt);
     retval = JOptionPane.showOptionDialog(DBPirate.appWindow,pan,
     "Password Input",                              JOptionPane.OK_CANCEL_OPTION,                              JOptionPane.QUESTION_MESSAGE,
     null,null,null);
     if(retval == JOptionPane.OK_OPTION)
          pwd = new String(txt.getPassword());
          setPassword(pwd);
          if(cryptoUtil.testPassword(pwd))
               valid = true;
          else
               tries += 1;
     else
          System.exit(0);
}Any help would be appreciated. Thanks, Jeremy

Hello Jeremy,
I am not too happy with my code, for I think there must be something more efficient and elegant. But after trying in vain with KeyListener and ActionMap this is presently the only way I could do it.

// button having focus is fired.

Need some help with JOptionPane

Hi everyone. I want to create an OptionDialog with 3 textfields. So we have...
String message1 = "The first Field";
JTextField tf1 = new JTextField();
String message2 = "The second Field";
JTextField tf2 = new JTextField();
String message3 = "The third Field";
JTextField tf3 = new JTextField();
Object o[] = {message 1, tf1, message2, tf2, message3, tf3};
int result = JOptionPane.showOptionDialog(this, o, "A dialog", JOptionPane.OK_CANCEL_DIALOG,JOptionPane.QUESTION_MESSAGE, null, null, null);
if(result == JOptionPane.OK_OPTION){
Various actions here
}However I want my dialog to focus in the first textfield, rather than, for example, in the OK button. I've tried a few alchemies but nothing actually worked. So I want your help :-). Is it possible to have the text indicator (you know that blinking | ) in the textfield? Can I do the same with a combo box too? I mean, how can I tell the programm to have selected the first option of the combobox when the dialog pops up?
Thanx in advance

Issue fixed.
try
            String m1 = "One Field";
            String m2 = "Two Fields";
            String m3 = "Three fields";
            JTextPane tf1 = new JTextPane();
            JTextPane tf2 = new JTextPane();
            JTextPane tf3 = new JTextPane();
            Object o[] = {m1, tf1, m2, tf2, m3, tf3};
            JOptionPane pane = new JOptionPane(o, JOptionPane.QUESTION_MESSAGE, JOptionPane.OK_CANCEL_OPTION, null, null, o[1]);
            JDialog dialog = pane.createDialog(this, "A new Dialog");
            dialog.setVisible(true);
            Object selectedValue = pane.getValue();
            if(((Integer)selectedValue).intValue() == JOptionPane.OK_OPTION)
                <<VARIOUS ACTIONS HERE!>>
catch(Exception e){ }Thnx everyone for stopping by!

JoptionPane need some help understanding, with buttons PLEASE SOMEONE :)

Hi all I was hoping that someone would be kind enough to explain to me how I can add a method to buttons in a JoptionPane.
Also can I pplease ask for you to look at this code I think I have stuff something as it is not working the way that I want,
I want to add something like this to the ok button.
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
       Object[] options = {"Cancel","OK",};
       int n = JOptionPane.showOptionDialog(null,
       "Do you really want to add a new shoe order for:"+ d +
       (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+" "+LastNameJText.getText(),"New Order",
       JOptionPane.YES_OPTION,
       JOptionPane.INFORMATION_MESSAGE,
       null,
       options,
    options[0]);
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();

When I do that i get
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2152, column 4
"Order.java": Error #: 300 : variable options not found in class epod_1_0.Order at line 2153, column 4
why would this be ?
This is the code
String check = LastNameJText.getText()+FirstNameJText.getText();
System.out.println(check);
      if
        //check to see if First & Last name have been entered.
        (check != null){
        return;
        else //create a dialog that shows Title,first & Last Name
         // & ask if you would like to make an new ordre
          String d= System.getProperty("line.separator");
      int result = JOptionPane.showOptionDialog(null,
   "Do you really want to add a new shoe order for:"+ d +
   (String) TitleComboBox.getSelectedItem()+" "+FirstNameJText.getText()+
    " "+LastNameJText.getText(),"New Order",
   JOptionPane.YES_OPTION,
   JOptionPane.INFORMATION_MESSAGE,
   null,
   options,
   options[0]);
switch(result){
   case JOptionPane.YES_OPTION: // Add your code for yes
      break;
   case JOptionPane.NO_OPTION: // Add your code for no
     dispose();
      break;
      if //Check to see if First & Last name text feilds are clear.
(check == null){
return ;
else
   //make sure that all text fields are clear for new order
        ClearAllTextFields();
}

STRANGE problem with JOptionPane.showMessageDialog .. HELP!!!

Please look at the code below and tell me what is wrong with it and my code is very very very simple!!! And I can't seem to understand why this error is coming up.

public ShowMessageDialog() {
//empty constructor for now
public void show () {
JOptionPane.showMessageDialog (null, "Please try again!!", "Error Message", JOptionPane.ERROR_MESSAGE);
}This class is invoked by another class named SendPacketBack which does nothing but checks for one condition in an if statment and then make an object of this class and calls this show() method and this error comes up. Please look at the error below and tell me why it is telling me java.lang.NoClassDefFoundError and not telling me which class???

Yes X server is alright. I should have mentioned one thing though in my previous email is that there is another class which extends JFrame and is part of the package that this class is in also running in the background but that class does not interact with this class at all and does not even know if it exists!
I don't know if that thing is causing some kind of problem which is not coming up here?

Help needed with project

Hello everyone. Some help would be appreciated. I have created a wildlife resort database with access.
It has an animals table with 5 entries, a species table with 3 entries and a user table with 3 entries.
I have set up a JDBC-ODBC bridge.
The server side of this application when run gets stuck upon pressing connect the first time so I have to run the server again while the first server window is running in the background and press connect for it to start running. The server works just fine after that. I can add and remove from the tables using the server.
When I run the client and try to connect it, it doesn't accept the hostname. I can't connect or log in.
I think the problem is with the threads but I'm not sure what to do to fix it.
Also I use java beans for coding.
These are some errors I get when running the client:

Hmm well my first reply didn't seem to make it.
I would recommend Castor if you are talking about supporting XML to save your Java Objects. Castor is a great XML-Java data binding tool that I personally love. You can just write a map between the XML and java elements and it can marshal and unmarshal for you. JAXB (Java API fo XML Binding) can do the same thing but you have to build the classes from a schema you can't just supply a map for it (so you might have to rework your classes). If you mean that you want to edit XML directly in the IDE then you might want to look at the DOM (Document Object Model), its memory intensive though.

Please help me! showInputDialog with specific Buttons

Hi all,
I'm from Germany and have some trouble with the JOptionPane package.
Everything works fine, but I have a german operationsystem and i'm writing an 1.4 application in english.
If I use a Optiondialog i can create my own buttontexts.
String[] options = { "Yes", "No" };
int n = JOptionPane.showOptionDialog(StartScreen.frame,
"Do you really want to quit ?", // Fragetext
"Are you sure ?", // Titel
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, // Icon
null, options, options[0]);
if (n == JOptionPane.YES_OPTION) {
Transfer.closeConnection();
System.exit(0);
That works, but here I see the german buttons, how can I choose specific Buttons here?
String response = (String) JOptionPane.showInputDialog(
          contentpane, // parent
          "Who is your favorite chipmunk?", // message
          "Pick a Chipmunk", // dialog title
          JOptionPane.QUESTION_MESSAGE, // icon type
          null, // no explicit icon
          new String[] {                     // choices
