Hi I am not exposed to under the hood of netbeans settings, hence require hand-holding.
Application is working fine in Netbeans IDE. But when I use a shortcut link to the jar file or try to run in the console, I get the following error message. ~~~~~ Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.UnsupportedClassVersionError: gabellattemvpn/GabellatteMVPn has been compiled by a more recent version of the Java Runtime (class file version 62.0), this version of the Java Runtime only recognizes class file versions up to 52.0 ~~~~~ Please inform what changes have to be done and where (Netbeans/Console). I am using MS Windows 11(or 10). Warm regards Amitabh Choudhury
