OK, got it. Looks like fixing my last problem created this one.
Many thanks for the quick response.

Hello All,
Below is a short program that I beleive I have transcribed correctly. It is just intended as an introduction to simple GUI programming. It compiles fine but when I try to run it I get "Exception in thread "main" java.lang.NoClassDefFoundError: demoFlowLayout
import javax.swing.*;
import java.awt.*;
public class demoFlowLayout extends JFrame{

private JButton one, two, three;
private Container container;
public demoFlowLayout()
{
super("Demo Flow Layout");
container=getContentPane();
container.setLayout(new FlowLayout());
one=new JButton("one");
two=new JButton("two");
three=new JButton("three");
container.add(one);
container.add(two);
container.add(three);
setSize(200,100);
setVisible(true);
}
public static void main(String args[])
{
demoFlowLayout application = new demoFlowLayout();
application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
I'm sure that I've made a simple error, but I just can't see it.

It's working now, Thanks!

Not to sound completely lost, but how do I add something to my classpath. What I've found online makes it seem like I can do it in the system applet of the control panel but slasspath is not one of the environment variables listed.

Hello All,
I have searched the message archive and not found an answer.
I have downloaded a class library that I need to make use of but I cannot seem to find any documentation on how to install it. I tried putting it into the 'include' folder but I am not able to access anything from the new library.
Any help will be greatly appreciated.

That was it. Thanks a ton!

Hello All,
I am just starting to learn Java. I am trying to learn on my own using the book "Java Programming Fundamentals" by Kimberly Seefeld. I like the book so far but I have run into a problem. I have typed up the following example program from the book:
// A simple program solving an equation with a variable.
public class solveForX2 {
public static void main (String args[])
{
int x=0;//variable is initialized
System.out.println("If x+3=8, what is x?");
x=8-3; //an equation to solve for x
System.out.println("x = " + x);
}
}
I save it as solveForX2.java and javac compiles it into solveForX2.class, but when I try to run it I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: solveForX2/class
I have checked it over multiple times and I cannot find any typos or mistakes on my part.
Can anyone tell me why this won't run?
Thanks,
Glen
