I have a jar file of version 1.8 and I want to execute it on the server. But I'm having java version 1.7 on the server.

How can I fix this?

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/inno/server/Server : Unsupported major.minor version 52.0
        at java.lang.ClassLoader.defineClass1(Native Method)

Two options: 1. Upgrade your server's java version 2. Downgrade your code's target version - there's no intermediate fix – ernest_k Jan 10 '20 at 05:39

Roughly speaking: the same way you install it on your local machine. Strictly speaking: speak to your sysadmin – ernest_k Jan 10 '20 at 05:46
