Have a look in the Java console and see why it's not loading.
It may be finding it ok, but it's throwing an unahndled exception.

Objects is pleased to announce the release of jstart, a Java application launcher.
If you've ever had any problem getting a Java class to run, or had no idea what to do with a jar file, or maybe just had enough of the command line, then you need to check out jstart.
For more information have a look at: http://www.objects.com.au/products/jstart
Or email us at jstart@objects.com.au

PS. Unfortunately at this time, jstart requires Java 1.2 or better to run.

If you are using your own tanble model check that you have implemented the setValueAt method correctly.
This methods needs to update your model data and fire appropriate events.

You can achieve this with a bit of a kludge. TRy:
JTextField tf = ...;
JOptionPane.showMessageDialog(parent, tf);

You can paint outside of the paint method.
However looking at your example, I don't think you can paint in an applet init method as the graphic context has not yet neen initialized. You need to wait until the applet is started.

What you've posted looks fine. Maybe double check your import's.
If you can post the offending source file it may give more clues.

I agree with Matt, unless your really pushing Swing to it's extremes then it should do a great job of building your gui.
I've written a quite a few Swing apps of varying levels of sophistication and have had few serious issues, and even less that couldn't be worked around.
As far as an IDE goes, it's a bit of a personal decision really.
Personally I've never found one I'd use they all just add a lot of fluff IMO. A good editor and compiler is all you need.
Writing the api and getting it working first is a good idea and Swing is well suited to this approach allowing a separation of the presentation logic and the application logic.
Best of luck with it.

I cannot think of any reason why JNDI would operate differently in Swing or AWT.

Sounds like there may be a problem in one of your listeners. These are called from the event dispatch thread so if an error occurs in these it'll screw up Swing's behaviour.
But w/out seeing your code it's hard to know exactly what the problem is.

If you want to post the relevant parts of your code I can have a look at it for you.

Use of deprecated methods should not affect your coding. Most deprecated methods work fine.
What you need to be aware of if that the fact that they are deprecated implies that those methods may not be available in a future jdk releases.

When you use actions, a JMenuItem object is still added to the menu.
If you look at the sig for add you'll see that it returns a JMenuItem:
public JMenuItem add(Action a);
You simply need to set the mneumonic on the returned menuitem:
JMenuItem item = menu.add(action);
item.setMnemonic(...

Not sure about the title bar, think it might be handle by the window manager of the OS so you could be limited to what you can do.
To change the icon, use setIconImage method in the Frame class.

Also have a look at www.solforum.com.
This is a Swing group communication tool we're also currently working on.
