JOptionPane.showInputDialog with echo chars

Is there any way to have use JOptionPane.showInputDialog() to have echo characters?
so that when you type something in the dialog, you can only see ***** just like JPasswordField

Is there any quick and easy way to use the
JOptionPane.showInputDialog with a JList? the default
is a drop down menu. Thanks!I have found a way to this. You need to write your own JOptionPane
class MyJOptionPane
    public static Object showListInputDialog(Component parentComponent, Object message, String title, Object[] selecttionValues)
        Object defaultOptionPaneUI = UIManager.get("OptionPaneUI");
        UIManager.put("OptionPaneUI", "MyBasicOptionPaneUI");
        Object object = JOptionPane.showInputDialog(parentComponent, message, title, JOptionPane.PLAIN_MESSAGE, null,
                selecttionValues, selecttionValues[0]);
        UIManager.put("OptionPaneUI", defaultOptionPaneUI);
        return object;
}And then create your own MyBasicOptionPaneUI extending from javax.swing.plaf.basic.BasicOptionPaneUI with 2 methods overridden. The codes are copied from javax.swing.plaf.basic.BasicOptionPaneUI and modified to get rid of JComboBox.
public class MyBasicOptionPaneUI extends BasicOptionPaneUI
    public MyBasicOptionPaneUI()
        super();
    public static ComponentUI createUI(JComponent x) {
         return new MyBasicOptionPaneUI();
    protected Object getMessage()
        inputComponent = null;
        if (optionPane != null) {
            if (optionPane.getWantsInput()) {
                /* Create a user component to capture the input. If the
                   selectionValues are non null with any size ,
                   it'll be a list, otherwise it'll be a textfield. */
                Object message = optionPane.getMessage();
                Object[] sValues = optionPane.getSelectionValues();
                Object inputValue = optionPane

JOptionPane.showInputDialog with JTextarea?

Hi,
is it possible to put a JTextArea into a JOptionPane.showInputDialog?
the reason i need to know is because my string is to long to fit into the current JOptionPane.showInputDialog.
Greeting

You could use your favorite component in other showXxxDialogs than the showInputDialog. Get the input on the component in an ActionListener or other appropriate event handler you've written for that component.

Help with JOptionPane.showInputDialog

Hi!!
People here helped me before so trying my luck again:)
In order to get information from people I use JOptionPane.showInputdialog,
problem is if I need to get 2 different types of info I have to use
naam = JOptionPane.showInputDialog(null, "Geef speler naam:");
land = JOptionPane.showInputDialog(null, "Geef Land Speler:");Is there anyway to make this happen in 1 screen?
Or do I have to make a new frame for that with textfields and such?
if so, anyone got an example?

im new here:) so.. New to Java Technology suits me
well I guess.No it doesn't. New to Java forum is for classpath questions, simple compile time problems and lazy students to cross post their assigments into.
Swing questions, such as the one you asked, should be asked in the Swing forum because the people who answer questions in there are more knowledgeable about Swing. Plus you will almost 100% likely to find working example codes from previous posts in the Swing forum for Swing related questions.
Much more likely than in here anyway.

Strange problem with JOptionPane.showInputDialog

I have a strange problem with JOptionPane.showInputDialog in that when I run a program anything that is typed in is displayed backwards, for example: I type this character > and this < is what is displayed.
I've uninstalled the sdk and reinstalled it twice but that hasn't solved my problem and the java plug-in in the control panel is displaying the same symptoms.
I did a search before posting this but all I got really was posts from people who wanted to reverse their text.
Thanks for your help on this.

Is it just the < and > characters?

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
               "Alvin", "Simon", "Theodore"
          "Alvin"); // default choice
Hope anyone can help me.
Thanks

in your main method :
Locale.setDefault(Locale.UK);
Then all default buttons will show in english.

JOptionPane.showInputDialog cancel brings up a blank box

String name = JOptionPane.showInputDialog(
    null,
    "My message",
    "My title",
    null,
    null,
    null) // real list of options deleted for brevityThis works okay, but when I press the cancel button, I get a blank warning JOptionPane (message box thingy)... how do I tailor the message in that? Been looking through the search results and API with little luck.

handle it like so
try
    String s = new JOptionPane.showInputDialog(null, "Enter input");
catch(Exception ee)
    JOptionPane.showMessageDialog("Invalid input");
}

Using JOptionPane.showInputDialog to return an integer

I am currently using JOptionPane to return a string from the Object array i made with all possible choices.
     private static boolean determineService(){
          JLabel label;
          label=new JLabel("Please select which Service Model to use.",JLabel.CENTER);
          Object[] possibilities = {"AddressCleanse", "VIN", "PostalCode"};
          serviceModel = (String)JOptionPane.showInputDialog(
                              null,
                              label,
                              "Select Service",
                              JOptionPane.PLAIN_MESSAGE,null,
                              possibilities,
                              "AddressCleanse");
//          If a string was returned, say so.
          if ((serviceModel != null) && (serviceModel.length() > 0)) {
              System.out.println("You've selected " + serviceModel + "!");
              setVariables();
              return true;
          }else{
//               If you're here, the return value was null/empty.
               System.out.println("Null or Bad service selected!\n Exiting program.");
               return false;
          }I would like to instead return the response as an integr so I can then use a switch, rather than recursive if, else if logic.
Apparently java doesnt allow switches to use strings (like PHP does)
any ideas?

Just a question more than an answer: would using a hashmap ever work here? where the key is a string and the value is an (???) object that implements an interface that would allow you to call an appropriate method? Perhaps one could use the keySet() and toArray to build the Object array for the JOptionPane. I thought I read something about this somewhere, but am not sure....

NEED HELP WITH WORD & CHAR COUNT USING HASHTABLE

I have to use a hashtable to be able to count all the words and characters (#'s, punctuations, etc) from a file
I have been able to get it to correctly count the words in the file but none of the characters and it also does not display the words alphabetically and just displays it in an odd way
Here's the code: public static void main (String [] args)
      Hashtable table = new Hashtable();
      String input = JOptionPane.showInputDialog("Enter the filename:");
      try{
      BufferedReader br = new BufferedReader(new FileReader(input));
      String s = br.readLine();
      StringTokenizer words = new StringTokenizer( s, " \n\t\r" );
        while ( words.hasMoreTokens() ) {
         String word = words.nextToken().toLowerCase(); // get word
         // if the table contains the word
         if ( table.containsKey( word ) ) {
            Integer count = (Integer) table.get( word ); // get value
            // and increment it
            table.put( word, new Integer( count.intValue() + 1 ) );
         else // otherwise add the word with a value of 1
            table.put( word, new Integer( 1 ) );
       } // end while
         String output = "";
      Enumeration keys = table.keys();
      // iterate through the keys
      while ( keys.hasMoreElements() ) {
         Object currentKey = keys.nextElement();
         output += currentKey + "\t" + table.get( currentKey ) + "\n";
         System.out.println(output.toString());
      catch (IOException e)
        System.out.println(e);
      }The output that I get for a file containing the line " Hi this is my java program" is:
this     1
this     1
program     1
this     1
program     1
hi     1
this     1
program     1
hi     1
java     1
this     1
program     1
hi     1
java     1
is     1
this     1
program     1
hi     1
java     1
is     1
my     1
I'm not sure what I am doing wrong and help would be greatly appreciated.

I have been able to get it to correctly count the
words in the file but none of the characters and it
also does not display the words alphabetically and
just displays it in an odd way
That's because hash tables are not ordered; to maintain order of insertion you could use LinkedHashMap and to maintain alphabetical order TreeMap.

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.showInputDialog without CANCEL Button

How can I do a JOptionPane.showInputDialog without CANCEL Button.
Besides if I press OK without tyoing anything, will a null String but returned?
Thanks

I don't think you can with an Input Dialog. Normally, you want to give the user a chance to cancel the operation. Here is an example using a Message Dialog. After the user hits OK, you can get the text from the text field.          JPanel p = new JPanel(new GridLayout(2,1));
          JTextField t = new JTextField();
          JLabel l = new JLabel("A message");
          p.add(l);
          p.add(t);
          JOptionPane.showMessageDialog(null,p,"Title",JOptionPane.PLAIN_MESSAGE);

JOptionPane.showInputDialog and Focus

I have a program that allows the user to type in a String in a text box and when they hit the enter key the text will appear in a text area. I've also added a menu bar to the program. When the user clicks on File and then Connect from the menu bar I want a JOptionPane to pop up that asks for the user to type in a username and then prompt for a password. And I've gotten all of that to work. Now for the problem. I click on file from the menu bar and then connect and it prompts me for the username as it should. I am able to just type in a phrase in the text field of the username dialog box and hit the enter key and then it prompts me for my password. I am still able to type in a phrase in the text field of the password Dialog box, however when I hit the enter key, the Dialog box does not close as it did for the username Dialog box. It will still close if I click on the OK button, but just pressing the enter key does not close the Dialog box as it did when it prompted for a username. I'm thinking I need to direct the focus to the password dialog box, but not sure how to go about doing this. Any help in solving this problem would be greatly appreciated.
Here is my code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class TestJOptionPane extends JFrame implements ActionListener{
     private static int borderwidth = 570;
     private static int borderheight = 500;
     private JPanel p1 = new JPanel();
     private JMenu m1 = new JMenu("File");
     private JMenuBar mb1 = new JMenuBar();
     private JTextArea ta1 = new JTextArea("");
     private JTextField tf1 =new JTextField();
     private Container pane;
     private static String s1, username, password;
     private JMenuItem [] mia1 = {new JMenuItem("Connect"),new JMenuItem("DisConnect"),
          new JMenuItem("New..."), new JMenuItem ("Open..."), new JMenuItem ("Save"),
          new JMenuItem ("Save As..."), new JMenuItem ("Exit")};
public TestJOptionPane (){
     pane = this.getContentPane();
          addWindowListener(new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
     dispose();
System.exit(0);
     setJMenuBar(mb1);
mb1.add(m1);
for(int j=0; j<mia1.length; j++){
     m1.add(mia1[j]);
p1.setLayout( new BorderLayout(0,0));
setSize(borderwidth, borderheight);
pane.add(p1);
          p1.add(tf1, BorderLayout.NORTH);
          p1.add(ta1, BorderLayout.CENTER);
          this.show();
          tf1.addActionListener(this);
          for(int j=0; j<mia1.length; j++){
               mia1[j].addActionListener(this);
     public void actionPerformed(ActionEvent e){
          Object source = e.getSource();
          if(source.equals(mia1 [0])){
               username = JOptionPane.showInputDialog(pane, "Username");
               password = JOptionPane.showInputDialog(pane, "Password");
          if(source.equals(tf1)){
               s1=tf1.getText();
               ta1.append(s1+"\n");
               s1="";
               tf1.setText("");
     public static void main(String args[]){
          TestJOptionPane test= new TestJOptionPane();
}

But using JOptionPane doesn't get the focus when you call itworks ok like this
import javax.swing.*;
import java.awt.event.*;
class Testing
public Testing()
    final JPasswordField pwd = new JPasswordField(10);
    ActionListener al = new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        pwd.requestFocusInWindow();}};
    javax.swing.Timer timer = new javax.swing.Timer(250,al);
    timer.setRepeats(false);
    timer.start();
    int action = JOptionPane.showConfirmDialog(null, pwd,"Enter Password",JOptionPane.OK_CANCEL_OPTION);
    if(action < 0)JOptionPane.showMessageDialog(null,"Cancel, X or escape key selected");
    else JOptionPane.showMessageDialog(null,"Your password is "+new String(pwd.getPassword()));
    System.exit(0);
public static void main(String args[]){new Testing();}
}

Web.show_document cannot display file with Chinese char in IIS 6

Dear all,
There is a problem that web.show_document cannot display file with Chinese char in IIS 6, but works fine in IIS 5.
Is it a server problem or is there any setting in server? Do you know how to solve it?
Big Thanks
JY

Hi,
As Francois mentioned, this issue has nothing to do with forms / web.show_document. web.show_document, just opens the URL specified as parameter. So, if you run the URL (that you've passed as argument for web.show_document), directly in the browser, you would be getting the same issue.
So, as you said, if it works fine in IIS 5 and does not in IIS 6, it would be an issue with the IIS and not forms. You might want to check out the IIS 6 release notes / documentation for any known issues / raise an issue in that.

Problem with special chars in BLOB datatype using contains keyword

Facing problem, when part searching with special chars in BLOB datatype. It is considering the non alpha-numeric chars as a separtor in a provided string
EX:
SELECT *
FROM RESUME_TEST P,grst_candidate d
WHERE d.candidate_id = p.candidate_id
AND CONTAINS(P.CAND_RESUME,'%VB.NET%',1) > 0
Strings: , VB.NET , PL/SQL AS/400 , C etc..
Followed the below approaches
1) created a table:
Syntax: create table resume_Test(cand_id number(10),cand_resume blob);
2) inserted the values into this table upto 60,000
3) created a context index
3.1 created preferences
Syntax:
BEGIN
ctx_ddl.create_preference('try_lexer3','BASIC_LEXER');
ctx_ddl.set_attribute('try_lexer3','printjoins','-_~!@#$%^&*(){}[],=?\;|><.+');
END;
3.2 created context index
Syntax:
CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('LEXER try_lexer3 memory 500M');
4) while executing this index, it is taking much time approx 6 hrs(plz explain why it is taking time)
5) Problems:
5.1 when searching with string(VB.NET , PL/SQL AS/400 , C etc..) it is considering the special char as a separator
5.2 used escape char (\) also, but no effect
5.3 when searching with single char, it is giving error (ORA-29902,ORA-20000,DRG-51030)
5.4 getting the above error with wild card chars (& ,_, (),{},[])
So, please explain the clear scenarios, why am getting this error , and how to get the proper results.

Have you tried adding the / char to the printjoin characters?
Indexing can take a lot of time, depending on the amount of data and your machine's power. You could try to parallelize the index creation and / or assign more memory
CREATE INDEX CANDRESUME_CTX_IDX ON resume_test (cand_resume)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('LEXER try_lexer3 memory 2000M') PARALLEL 8;

All podcasts sound slow and and a played with echos after upgrading to 3.0

Hi everybody, after I upgraded to 3.0, all my voice files (e.g. podcasts) are played slowly and with echos. I reset the device to factory settings and re-synched (this took almost two hours), and the effect is still there. The sound files are OK if I play them from itunes. Did anybody else meet this phenomenon? Can I downgrade to solve it? Any advice is welcome.
