add scrollbar in JFrame with null Layout

[sajib_bd]

I am using following code to create a frame. I want to add scrollbar on it.

jobConfFrame=new JFrame("Resource Configuration Panel");
jobConfFrame.setLocationRelativeTo(null);
jobConfFrame.setDefaultCloseOperation(jobConfFrame .DISPOSE_ON_CLOSE);
jobConfFrame.setSize(400,400);
jobConfFrame.setResizable(false);
jobConfFrame.setVisible(true);
jobConfFrame.getContentPane().setLayout(null);

I tried to add a scrollbar, but for some reason it was not visible on the frame (may be for the null layout). If you have any idea to solve the problem, please send the solution.

Read the API for JScrollPane and follow the link to the Swing tutorial on How to Use Scroll Panes. Note that if you use a null layout (which I strongly recommend against) you have to assume the responsibility of supplying a preferredSize for the scorll pane's viewport view.
