                               /       \
                        classes         source
                      /    |   \             \
            MyApp.class    |   app.jar       MyApp.java
                     manifest.txt

I have app.jar inside of classes folder. Now I want to execute the app.jar file.
but when i run using "java -jar app.jar", I got error "no main manifest attribute, in app.jar".
Tell me Why am I getting this error? and How to execute this JAR file.

How, exactly are you trying to run this JAR file? Are you doing it programmatically from within your project, or are you trying to run it from command line? – MarsAtomic Oct 24 '20 at 23:57
