hi @anantharamulu_g ,

You can convert a regular JAR file into an executable JAR file by following these steps:

1. Create a file named MANIFEST.MF in the same directory as your JAR file. Add the following contents to the file:

 

Manifest-Version: 1.0 Main-Class: com.example.MainClass​

 

 

 

2. Open a command prompt or terminal window.Navigate to the directory containing your JAR file and the MANIFEST.MF file and Run the following command:

 

jar cfm myapp.jar MANIFEST.MF com/example/*.class

 

 

 

3. To test the executable JAR file, Run the following command to start your application:

 

java -jar myapp.jar

    Hi @anantharamulu_g ,

     

    I think you are facing some issues with opening this JAR, it is executable by default. the problem here seems to be here ".jar" in your filename. Could you try after removing it? 

    I have seen this problem on Windows, where sometimes adding an extension makes it unusable. (Check you view setting of windows).

     

    Also, try to open this file using the command prompt using

    java -jar <youraemjar>

     

    Hope this helps!

     

    Regards,

    Nitesh
