How to open a html file?

Question

I have been trying to open a htmlfile on clicking help button. And i need to import the file to source package so after build it wont show errors. I am using netbeans. When i copied the file to src and tried running the file it showed error in compiling. I want to know how to add the file to src and how to open by asking the user with a list of browsers installed in the system. Here is the code i have searched and tried..Thanks in advance

  try 
  {           
      File htmlFile = new File(this.getClass().getResource("help.html").getFile());
      Desktop.getDesktop().browse(htmlFile.toURI());
  } 
  catch (IOException ex)
  {
      System.out.println(ex);
  }

Try this one.

import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Desktop;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class FileOpenBrowser {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        JFrame frame = new JFrame("FileOpenBrowser"); // set API Name
        JPanel topPanel = new JPanel(new FlowLayout()); // set Panel Layout

        Button btn = new Button("Help");
        btn.setBounds(50, 100, 60, 30);
        topPanel.add(btn);

        frame.add(topPanel, BorderLayout.PAGE_START);

        frame.setSize(300, 300);
        frame.setVisible(true);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        btn.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                try {
                    System.out.println("Start..");
                    File file = new java.io.File("src/help.html").getAbsoluteFile();
                    Desktop.getDesktop().open(file);                    
                    System.out.println("End..");
                } catch (Exception e1) {
                    e1.printStackTrace();
                }
            }
        });
    }
}
