Hide border of transparent JScrollPane In Java

I have implemented JScrollpane and I had set opaque false. Now the problem is I am not able to hide it's border.

Code:

JPanel chapterContainerPanel = new JPanel();
JScrollPane chapterScrollPane = new JScrollPane(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
chapterContainerPanel.setOpaque(false);
chapterScrollPane.setViewportView(chapterPanel);
JLabel blankLabelChapter = new JLabel();
blankLabelChapter.setOpaque(false);
blankLabelChapter.setPreferredSize(new java.awt.Dimension(150, 50));
blankLabelChapter.setRequestFocusEnabled(false);      
chapterContainerPanel.add(blankLabelChapter,BorderLayout.WEST);
chapterContainerPanel.add(chapterScrollPane,BorderLayout.CENTER);
chapterScrollPane.setOpaque(false);
chapterScrollPane.getViewport().setOpaque(false);

enter image description here

I want to hide the border which is shown by arrow.

I have tried two ways:

Border border = BorderFactory.createEmptyBorder( 0, 0, 0, 0 );
chapterScrollPane.setViewportBorder( border );
chapterScrollPane.setBorder(border);
chapterContainerPanel.setBorder(null);

and 

chapterScrollPane.setBorder(null);
chapterScrollPane.setViewportBorder(null);

but both are not working.

I was having the same problem, and this worked for me:

chapterScrollPane.setBorder(BorderFactory.createEmptyBorder());
chapterScrollPane.setViewportBorder(BorderFactory.createEmptyBorder());

Doing this that border will no longer appear, but the content of the panel inside the Scroll might go under the ScrollBar, so you need to adjust the border of the panel that is on the ViewPort, chapterContainerPanel in your case. You can also use an empty border to solve this, like that:

chapterContainerPanel.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 12);
