Here is the solution that should work for any size text and any maximum width. This solution will lock the JTextPane to the maximum width while allowing the dialog height to grow to fit the text.
import javax.swing.*;*
import java.awt.*;
public class FooDialog extends JDialog{
   public static void main(String args[]) {
      final int MAX_WIDTH = 256;
      //build the dialog
      FooDialog dialog = new FooDialog();
      JTextPane textPane = new JTextPane();
      textPane.setEditable(false);
      textPane.setText(
      "FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR FOOBAR");
      JScrollPane scrollPane =
         new JScrollPane(textPane,
                                  JScrollPane.VERTICAL_SCROLLBAR_NEVER,
                                  JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
      scrollPane.setBorder(null);
      scrollPane.setPreferredSize(new Dimension(MAX_WIDTH, 0));
      dialog.add(scrollPane, BorderLayout.CENTER);
      //show the dialog
      dialog.pack();
      JViewport viewport = scrollPane.getViewport();
      viewport.doLayout();
      scrollPane.setPreferredSize(viewport.getViewSize());
      dialog.pack();
      dialog.setVisible(true);
}The first pack() will lay out the dialog, but the viewport.doLayout() will insure that the JTextPane is laid out. (Which rarely happens with the first pack() alone.) The last pack() re-lays out the dialog with the JScrollPane 's new preferred size--the view size that the JTextPane became during the viewport.doLayout() .
