No constructor in JFrame matches init (String)

Question

Hello,
I am using Forte for Java 2.0 build 1160 to compile my Java code. Upon compilation I get the following error message:
DemoShape.java [33:1] No constructor in JFrame matches <init>(String)
        super("DemoShape Applet");
        ^
1 errorThe odd thing is this code worked before. Also, when I use javac in a DOS prompt, the program compiles and runs fine. What is causing this problem.
My code is below. I cannot seem to find any error:
//import the necessary java packages
import java.awt.*;   //for the awt widgets
import javax.swing.*;  //for the swing widgets
import java.awt.event.*;  //for the event handler interfaces

The problem must be something with the Forte configuaration because there is most definatley a JFrame(String str) constructor and you are calling Super as the first line in your constructor so I would check and make sure that Forte is using the right JDK, maybe its trying to use Java 1 and thats causing the problem, I'm really not sure I don't use Forte but I can tell you its not the code thats the problem.
