I don't have time to figure out why your code isn't showing the
sliders on the scrollbars, even when the contents of the textarea is
bigger than the scrollpane, but I changed your code to the way I would
do it (sort of) and it worked:

private void jbInit() {
setSize(800, 600);
// textArea.setPreferredSize(new Dimension(760, 520)); // DELETE
textArea.setWrapStyleWord(true);

Scroller.setHorizontalScrollBarPolicy(

JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);

Scroller.setVerticalScrollBarPolicy(

JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
Scroller.getViewport().add(textArea, null);
tab1Pan.setLayout(new BorderLayout()); // ADD
tab1Pan.add(Scroller, BorderLayout.CENTER); // CHANGE
// tab1Pan.add(Scroller);
Tabbed.addTab("TAB 2", tab1Pan);
Tabbed.addTab("TAB 2", tab2Pan);
getContentPane().add(Tabbed);
}

I was dumb-founded why the bars would not scroll (or even appear as you
pointed out)

Problem solved.......

Thankyou!
