I am getting this error when running jar file on linux - Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger

Question

I created a java project and when I run it from NetBeans it runs correctly and does what is supposed to but when I move it on the Linux server it gives me this error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger
    at arhivare.Arhivare.<clinit>(Arhivare.java:29)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

It has to to with log4j library which I included in the project (it runs in Netbeans). What am I missing ?

Can you show the code ? how you initialize your `Logger` ? – Khalid Shah Jul 12 '19 at 09:52 — Khalid Shah, Jul 12 '19 at 09:52
What's the command you use to run your application? – zaerymoghaddam Jul 12 '19 at 09:53 — zaerymoghaddam, Jul 12 '19 at 09:53

-1

 public static final Logger logger = Logger.getLogger(Arhivare.class);

This is how I initialize my Logger and the command to run the application is: java -jar ArhivareProd.jar
