JEditor Pane - HTML Page

[Akshay Sharma]

I am using the following code to display a HTMLpage.
But the pane is not visible even though its set to true...
No exception is beinmg thrown.
*****************************************************
helpMenuItem.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent event)
{
try
{
helpPane = new JEditorPane();
helpPane.setEditable(false);
helpPane.setContentType("text/html");
File htmlFile=new File("test.html");
URL helpUrl=htmlFile.toURL();
helpPane.setPage(helpUrl);
helpPane.setSize(400,400);
helpPane.setVisible(true);
}
catch(Exception e)
{
e.printStackTrace();
}
}
});

A JEditorPane is not a top-level window, it's a component that must be added to a window to be shown. So, for instance, you might add

JFrame frame = new JFrame();
frame.getContentPane().add(helpPane);
frame.setVisible(true);

at the end of the try block below. Also note that the setVisible() call on helpPane doesn't do anything and can be removed.
