Problems trying to use JEditorPane Class

[Chris Williams]

I am trying to use the JEditorPane class to display some basic text files.
Every time i try, I keep getting a NULL pointer error. Here is my code and
output.

////////////////////CODE
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
import java.io.*;

public class TJEditorPane extends JFrame
{
public TJEditorPane()
{
super( "Test Editor Pane" );
Container container = this.getContentPane();

JEditorPane editorPane;

File file = new File( "c:\\sms.ini" );
try
{
if( file.exists() )
{
System.out.println( "File: " + file.getPath() );
System.out.println( "URL: " + file.toURL() );
editorPane = new JEditorPane( file.toURL() );
container.add( editorPane );
//editorPane.setPage( file.toURL() );
//FileInputStream stream = new FileInputStream( file );
//editorPane.read( stream, "Test Stream" );
}
}
catch( Exception e )
{
System.out.println( "Exception: " + e );
}
show();
}

public static void main( String[] args )
{
new TJEditorPane();
}
}

/////////////OUTPUT
File: c:\sms.ini
URL: file:/c:/sms.ini

The file exists and I do have read permission on it. Any help in figuring
out what is wrong would be great!!
Thanks

Looks like after some trial and error.....the editor pane relies on using
the file extension of the file to determine the type. Once I set the text
file to have a .txt at the end..it worked fine.
