Text wrap in JOptionPane?

I'm using following code to display error message in my swing application

try {
    ...
} catch (Exception exp) {
    JOptionPane.showMessageDialog(this, exp.getMessage(), "Error", JOptionPane.ERROR_MESSAGE);
}

The width of the error dialog goes lengthy depending on the message. Is there any way to wrap the error message?

Solution

A JOptionPane will use a JLabel to display text by default. A label will format HTML. Set the maximum width in CSS.

JOptionPane.showMessageDialog(
    this, 
    "<html><body><p style='width: 200px;'>"+exp.getMessage()+"</p></body></html>", 
    "Error", 
    JOptionPane.ERROR_MESSAGE);
