JTextPane does not wrap

Question

i have written a code by using JTextPane, however, it does not seem to be wrapping the long texts. The method below creates a JTextPane withing a JPanel and returns the JPanel. i add the JPanel to another panel with TableLayout later. can someone tells why it is not wrapping?
    public JPanel createMessagePanel(String message) {
        JPanel mesPanel = new JPanel();
        JTextPane textPane = new JTextPane();
        try {
            StyledDocument doc = (StyledDocument) textPane.getDocument();
            Style style = doc.addStyle("StyleName", null);
            StyleConstants.setFontFamily(style, "SansSerif");
            StyleConstants.setFontSize(style, 30);
            StyleConstants.setAlignment(style, StyleConstants.ALIGN_LEFT);
            doc.insertString(doc.getLength(), message, style);
        } catch (BadLocationException e) {
        mesPanel.add(textPane);
        return mesPanel;
    }

Answer 1

It is only because the default layout manager for the JPanel is
a FlowLayout that try to use the maximum width.
With the BorderLayout you are limited to the available width so the textpane can wrap.
I tell you to use a JScrollPane because if the text is too long you will have to scroll.
