cannot find symbol

[sahana mithra]

Hi all
I keep getting cannot find symbol for the imports, layouts, events in NetBeants IDE.

import java.awt.event.*;  //cannot find symbol
import java.awt.*;
import java.awt.BorderLayout;   //cannot find symbol
import java.awt.Color;  //cannot find symbol
import java.awt.Font;        //cannot find symbol
import java.awt.Window;   //cannot find symbol
import java.awt.event.WindowAdapter;  //cannot find symbol
....
f = new Font("SanSerif",Font.PLAIN,24); //cannot find symbol
        setFont(f);
        setLayout(new BorderLayout());  //cannot find symbol 

can anyone help me ?
Thanks

Looks like Netbeans cannot find the java classes on the classpath. Have you configured your IDE/project properly?

This question is not really a Swing problem. Moving to the IDE forums

What OS are you using? NetBeans tends to want to use the JDK you had installed when you first installed NetBeans; if you later delete that version of the JDK because you upgraded to a new one, NetBeans tends ot have issues. Check the etc/netbeans.conf file (inside the NetBeans installation directory), and verify that the netbeans_jdkhome property value is pointing to your JDK.
