We need a bit more information. Also you may be using a wrong layout manager. have you gone over the layout manager tutorial at the Sun Swing tutorials? If not, you should as it will help you.

I have added the code for your kind reference. I am trying draw some vertical lines in drawPanel and the size is not changing. So I am unable to use the scrollbar. I didnt use any layout managers as I used netbeans and the layout manager I used is freedesign just drag and drop.

I suggest that you learn how to use other layout managers, managers that may help you resize your panel better. You can read up on them here: Lesson: Laying Out Components Within a Container (The Java™ Tutorials > Creating a GUI with JFC/Swing)

Also, when posting code here, please use code tags so that your code will retain its formatting and thus will be readable -- after all, your goal is to get as many people to read your post and understand your code as possible, right?

To do this, highlight your pasted code (please be sure that it is already formatted when you paste it into the forum; the code tags don't magically format unformatted code) and then press the code button, and your code will have tags.

Another way to do this is to manually place the tags into your code by placing the tag [code] above your pasted code and the tag [/code] below your pasted code like so:

[code]
  // your code goes here
  // notice how the top and bottom tags are different
[/code]

I am really sorry. Thank you for your help.

//code to draw vertical lines





Graphics g = drawPanel.getGraphics();


Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASIN G,RenderingHints.VALUE_ANTIALIAS_ON);


int dwidth = 0;
dwidth = (width/20) ;//10=processmax

if(dwidth < 30)
{
dwidth = 70;
}

int dheight = 0;
dheight = height - 50;




int x1 = 30 ; //left
int y1 = 50; //top --- Constant value
int x2 = 30 ; //right
int y2 = dheight; //bottom
int y3 = y1-10; //for process no. string
int x3 = x1-5;

for (int i = 0;i <= 20;i++)
{
g2.setColor(Color.BLACK);
g2.drawLine(x1, y1, x2, y2);
g2.setColor(Color.BLUE);
g2.drawString("P"+i,x3 , y3);
x1 = (x1 + dwidth);
x2 = (x2 + dwidth);
x3 = (x1 - 10);

}



int height1 = drawPanel.getHeight();
int width1 = drawPanel.getWidth();
System.out.println("Height of DrawPanel new " + height1);
System.out.println("Width of DrawPanel new " + width1);

JScrollPane scroll = new JScrollPane(drawPanel);

scroll.setSize(600,800);
if(drawPanel .getSize().height > scroll.getSize().height)
{ scroll.createVerticalScrollBar(); }

if(drawPanel.getSize().width>scroll.getSize().widt h)
{ scroll.createHorizontalScrollBar(); }
