Java Programming

Hi all,
I need to pass a Jpanel to an object. I have added my code below.

public void createFrame(Object panel){
		JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
		frame.getContentPane().add( (Jpanel)panel);
		frame.pack();
		frame.setVisible(true);
	}

In this

frame.getContentPane().add( (Jpanel)panel);

shows error as 'Jpanel' cannot be resolved to a type.
What is the correct approach for this?
Please help.
