HTML TextArea is a JScrollPane in JEditorPane?

Question

Hi all,
I'm trying to create an autofill facility for my application, to do this I am getting the components from the HTML document and converting them to their Java Swing counterpart.
So for example <input type="text" name="example" /> would be a normal text input field on a HTML form, and its Swing conversion is a JTextField - this works as desired and it allows me to use the .settext() command to set the text on the HTML form - i.e. autofilling.
My problem comes when I try to get the component for a HTML textarea, e.g. <textarea name="example"></textarea> - I would expect the Swing component to be a JTextArea, but the class it gets converted to is a JSrcollPane! This leads to a problem as I can't set the text of a JScrollPane as it is a container.
Does anyone know how I might get around this problem so that I can set the text for the textarea? I've included my code below.
Many thanks

        JButton b1 = new JButton("Auto Fill");
        this.getContentPane().add(b1,BorderLayout.SOUTH);
        b1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
                for ( int i = 0; i < pane.getComponentCount(); i++ )
                    Container c = (Container)pane.getComponent(i);
                    Component swingComponentOfHTMLInputType = c.getComponent(0);
                    System.out.println(swingComponentOfHTMLInputType.getClass());
                    if ( swingComponentOfHTMLInputType instanceof JTextField ) {
                        JTextField tf = (JTextField)swingComponentOfHTMLInputType;
                        tf.setBackground( Color.yellow );
                        tf.setText("Auto Filled");
                    if ( swingComponentOfHTMLInputType instanceof JScrollPane ) {
                        JScrollPane ta = (JScrollPane)swingComponentOfHTMLInputType;

        Tester app = new Tester();
        app.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        app.setSize( 400, 400 );
        app.setVisible( true );

Hi Jim,
Thanks for the suggestion, but I've already tried that and although it does work from a visual POV, when you then submit the form the data in the JTextArea isn't added - it just says the field is blank.
Although, I'm not sure whether it's not working due to the method I've had to use to add the JTextArea: -
JScrollPane ta = (JScrollPane)swingComponentOfHTMLInputType;
JTextArea oTextArea = new JTextArea();
oTextArea.setText("Hello World!");
ta.setViewportView(oTextArea);I'm not sure if it's not working because I've had to use .setViewportView(); rather than .add(). If I use .add() then no changes are reflected on screen and the JTextArea isn't actually added.
Any other suggestions?
