How to find the manifest class of a jar file I have an application bundled in a jar file which I need to launch on Linux environment, but I am unable to figure out which class within this JAR file is the applications entry point. I tried to run it on Windows CMD as below java jar build. It raised the following error no main manifest attribute, in build. Instasize For Computer No. Any help would be highly appreciated.
