AWTEvents errors and deprecated methods

[Michael G]

I am getting some errors/warnings that I don't understand. This code is in
a Java app that uses Swing J Components with an ActionListener. The
code/errors/warnings follow. Thanks for any help, Mike

import javax.swing.*;
import java.awt.event. *;
import java.awt.*;

public class GraphicalImp extends UIImp implements ActionListener
{


....//snipped code

public void actionPerformed (ActionEvent e)
{
String input = userInput.getTe xt().trim();
choice = Integer.parseIn t(input);
String searchKey = otherInput.getT ext().trim();
int userSelection = facade.getUserS election();
String[] resultSet = facade.
processUserSele ction(userSelec tion,searchKey) ;
facade.displayR esultSet(result Set);

}

The problem with these errors is that it is in Sun's code not mine. I am
using jdk1.4.1 and I have the associated docs. Makes no sense to me.

Thanks, Mike

Finally figured it out. It was a compatibility error. I was using an IDE,
I won't mention which one, and it was giving me a NullPointer exception if I
ran it in the normal mode and it wouldn't throw the exception if I ran it in
the debug mode. So I had the brilliant idea of using a command-line javac.
The IDE placed the .class files in a jar, so I just let MY javac, not the
IDE's, create .class files in the current dir. Anyway, once I did that the
goofy errors started showing up. I don't totally understand why. To make a
long story short - I spent almost all day yesterday trying to figure this
thing out - I had too many versions of Java on my pc and I made the mistake
of assuming that Java was consistent between versions. Shame on me.
Jeff thanks for your help. Your insight got me on the right track.
