    This looks like a new question regarding databases.
    You will get a better response if you ask it in the database section of the forum.

    If you receive the text as a single String, and work with it as a single String, and save it as a single String
    can you explain what is the problem?

    Does the code you are working with break the String up into multiple Strings? Can you keep the code from doing that?
    Leave all of the contents in a single String.

    I want it in the same format I entered
    I don't understand how the contents of the String gets changed.
    If there are spaces and line ends in the String, what removes them?

    Can you write a small program that compiles, executes and shows the problem?

    Sorry, I don't know what a "document-modal" is. Can you post a small simple program that compiles, executes and shows the problem?

    What is contained in the String returned by the textarea's getText() method?

    FIRST:
    String str = queryTextArea.getText();
    final JTextArea textArea = new JTextArea();
    textArea.setFont(new Font("Sans-Serif", Font.PLAIN, 12));
    textArea.setText(str);
    textArea.setCaretPosition(0);
    JScrollPane scrollPane = new JScrollPane(textArea);
    scrollPane.setPreferredSize(new Dimension(350, 150));
    int res = JOptionPane.showConfirmDialog(null,scrollPane,"Que ry", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
    System.out.println( "showInputDialog: " + res );
    if(res==0)
    queryTextArea.setText(textArea.getText());

    Using this I'm unable to resize the document-modal

    SECOND:

    String str = queryTextArea.getText();
    final JTextArea textArea = new JTextArea();
    textArea.setFont(new Font("Sans-Serif", Font.PLAIN, 12));
    textArea.setText(str);
    textArea.setCaretPosition(0);
    JScrollPane scrollPane = new JScrollPane(textArea);
    scrollPane.setPreferredSize(new Dimension(350, 150));
    JOptionPane pane = new JOptionPane(scrollPane, JOptionPane.PLAIN_MESSAGE,JOptionPane.PLAIN_MESSAG E);
    JDialog dialog = pane.createDialog(null, "Query");
    dialog.setResizable(true);
    dialog.setVisible(true);

    Using This I'm unable to get which button is pressed (OK/Cancel/Closed using X)

    Please Help..

    Thanks

    Can you post a small, complete program that compiles, executes and shows the problem?

    Please Edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    You can get the user's selection from your pane variable:

     
          JTextArea tArea = new JTextArea(10, 40);
          JScrollPane sPane = new JScrollPane(tArea);
          JOptionPane pane = new JOptionPane(sPane,
                JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION);
          JDialog dialog = pane.createDialog(null, "Query");
          dialog.setResizable(true);
          dialog.setLocationRelativeTo(null);
          dialog.setVisible(true);
     
          // get the user's selection here:
          Object value = pane.getValue();
          System.out.println("value: " + value);
     
          // first make sure that the user didn't kill the window by pressing on the upper left "x" button
          // which will make the value returned null:
          if (value == null) {
             System.out.println("dialog killed");
          } else if (value.equals(JOptionPane.OK_OPTION)) {
             System.out.println("OK pressed");
          } else if (value.equals(JOptionPane.CANCEL_OPTION)) {
             System.out.println("Cancel pressed");
          }

    This information is all available for you in the JOptionPane API. I suggest you give it a look!

    ArrayIndexOutOfBoundsException:
    That means the index being used is past the end of the array.
    Remember that array indexes go from 0 to the array length-1.
    Check the value of the index and make sure it does not go past the end of the array.
    If you don't understand my answer, don't ignore it, ask a question.
