Can't find textbox class - help please!

Question

I'm posting this again, in the hope that more people might help. I already know that the error means that the compiler can't find the class Textbox. I need to know why, because I've copied the relevant parts of the code from another app that builds fine. So why won't this build?
I'm trying to write and build my first J2ME app. My code starts:
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
import java.lang.Math;
public class TestMIDlet
extends MIDlet
implements CommandListener
private Textbox tbMain;
public void startApp()
The build fails with numerous errors of which the first is:
C:\WTK22\apps\TestMIDlet\src\TestMIDlet.java:9: cannot find symbol
symbol : class Textbox
location: class TestMIDlet
private Textbox tbMain;
with the caret under the 'T' of Textbox
I don't understand what's wrong with this, as it's in many of the sample apps I've looked at.
Thanks
Ed

Thanks very much!
I've lost count of the times I've been caught by that case-sensitivity thing in Javascript. I thought it was just the first letter that had to be capitalised. Progress at last!
