I can build and run my jFrame project in Netbeans IDE 21.
If I go to the folder where my .jar file is and double click on it, nothing
happens. If I go to a console and run it with the command java -jar BFC.jar I
get an error
no main manifest attribute, in BFC.jar
If I use the command java xf BFG.jar and look at the MANIFEST file, there is no
Main-Class line. After I add the line with the main class, I get this error.
Error: Could not find or load main class iss.batchfilegenerator.BFG
Caused by: java.lang.ClassNotFoundException: iss.batchfilegenerator.BFG
In net beans I have iss.batchfilegenerator.BFG. specified as the main class
under project|properties
|Run.
Here is the code
package iss.batchfilegenerator;
import javax.swing.JFileChooser;
import javax.swing.filechooser.FileNameExtensionFilter;
import java.io.File;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
