无法运行使用launch4j转换的Java应用程序（exe）

Question

I converted a java program (Number Guessing Game) to .jar but it did not run on double clicking so,ran it on cmd (it worked) now i converted it to .exe using launch4j but the application does not work either . Help!

Answer 1

1. Open your jar file with one zip application (ex winrar)
2. go to META-INF folder and open the file MAINIFEST.MF
3. put your main class there as follows

Main-Class: your-packaging.YourMainClass

4. save this file and try to create your exe file again

This will make your jar runnable , therefore when you create an exe file using Launch4J, your application will execute once you double click on that

If in any case your application did not run again, you have dependency problem . for solving that you should also add Class-Path: within your MANIFEST.MF file!
