Eclipse/java problem

[falkenberg_cph]

Hi
I have a problem with this program from Cay Horstmans "Java Concepts" - Project 2.2 (page. 62).
If i execute the program as mr. Horstman has written it, without "import java.awt.Color;" - i get a compiler error.
On the other hand, if i add "Import java.awt.Color;", i dont get a compile error, but eclipse gives me an error when i run the program. I am not at home right now, but when i am, i will post the eclipse error message.

Thanks
Carsten



import javax.swing.JFrame;
import javax.swing.JTextField;

// This is what i have added to the program
import java.awt.Color;

public class FrameTester
{
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setSize(200, 200);
JTextField text = new JTextField("Hello, World!");

text.setBackground(Color.PINK);
frame.add(text);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
frame.setVisible(true);
}
}

Ran fine for me in Eclipse, other than the typo in the code you posted on line 17.

Any chance your project is using incorrect compiler settings? Perhaps you're still using 1.4? Even if you open ecilpse using a newer JDK, it defaults to 1.4. That causes all kinds of errors. From the toolbar:
Window -> Preferences -> Java -> Compiler

Yep. that was it, i was using 1.4 - i did what you said, and it almost helped.
For others having this problem, i also had to do the following:

Window -> preferences -> java - installed JREs
found JRE 1.5.0_10 (at the moment) - unchecked JRE 1.4

windows -> preferences -> compiler -> compiler compliance level 5.0
tried 6.0 at first, but that didnt work

Thanks for your help

Yeah, in the tutorial on Java in my sig, I mention the JRE settings, too. But you figured out and most people do. Glad you're up and running. Cheers.
