[JAVA] Java Swing

Hey Guys!
I though of doing something a little different than plugins.
I have always made plugins that are complex, and since I am self taught, I don't know some basics.
For example, I decided I would make a stand alone application in Java.
I basically tried to make a simple GUI application.
I am using the Java 7 jdk in Eclipse.
I made this class.

Code:java

package me.bluemustache.installer;
 
import javax.swing.JFrame;
import javax.swing.WindowConstants;
 
public class Installer{
 
public static void main(String args[]){
JFrame myFrame = new JFrame("This is my frame");
myFrame.setSize(300,400);
myFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
myFrame.setVisible(true);
}
}
 

Does anyone know if I am doing something wrong?
I compiled this one class as a jar, then ran it, and poof. Nothing.
Please help,
-Blue

 

Bump.

 

BlueMustache before setSize, call setPreferredSize with the same argument. Also, call frame.setLocationRelativeTo(null); somewhere.

 

BlueMustache Did you set your main file? If you are using Eclipse you do it by exporting and clicking next until you see this Click Me then set your main file.
