dialog box i want to diable the OK button,i dont know how to do this,
coding which i used was,
getButton(IDialogConstants.OK_ID).setEnabled(false); -->it throws null
pointer exception
and i used
getButtonBar(),getShell().getDefaultButton() --> all this also
throws null pointer exception.

I did this with Cancel button the following code:
protected void createButtonsForButtonBar (Composite parent)
{
createButton (parent, IDialogConstants.OK_ID, "Ok", true) ;
}
So you override that method and only create the button(s) you wish.
Assuming you use the correct ID, then you Cancel button will work fine.

You cannot call this method until after the button bar has been created.
i.e., if you try to call it in the createDialogArea(), it will throw a NPE.
So, either:
a) Override createButtonBar() and after super.createButtonBar(), disable the
OK button.
or
b) Override create() and after super.create(), disable the OK button.

If you don't want the default set of buttons, don't call
super.createButtonBar()
