To break a message in two or more lines in JOptionPane

try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        String connectionUrl = "jdbc:sqlserver://"+hostName.getText()+";" +
        "databaseName="+dbName.getText()+";user="+userName.getText()+";password="+password.getText()+";";
        Connection con = DriverManager.getConnection(connectionUrl);
        if(con!=null){JOptionPane.showMessageDialog(this, "Connection Established");}
        } catch (SQLException e) {
            JOptionPane.showMessageDialog(this, e);
            //System.out.println("SQL Exception: "+ e.toString());
        } catch (ClassNotFoundException cE) {
            //System.out.println("Class Not Found Exception: "+ cE.toString());
             JOptionPane.showMessageDialog(this, cE.toString());
        }

When there is an error it shows a long JOptionPane message box that is longer than the width of the computer screen. How can I break e.toString() into two or more parts.

Solution

enter image description here

import javax.swing.*;

class FixedWidthLabel {

    public static void main(String[] args) {
        Runnable r = () -> {
            String html = "<html><body width='%1s'><h1>Label Width</h1>"
                + "<p>Many Swing components support HTML 3.2 &amp; "
                + "(simple) CSS.  By setting a body width we can cause "
                + "the component to find the natural height needed to "
                + "display the component.<br><br>"
                + "<p>The body width in this text is set to %1s pixels.";
            // change to alter the width 
            int w = 175;

            JOptionPane.showMessageDialog(null, String.format(html, w, w));
        };
        SwingUtilities.invokeLater(r);
    }
}
