Error: Could not find or load main class xxx Linux

Question

I am very new to linux environment.

I am trying to run an simple hello world java class in linux environment.

Hello .java

 package com.util;

    public class Hello {

        /**
         * @param args
         */
        public static void main(String[] args) {
            System.out.println("hi");

        }

    }

I have compiled java class in windows environment and uploaded the .class file to linux system into /home/scripts path.

my command is as follows,

java -cp /home/scripts com.util.Hello

when i am executing this command from this same /home/scripts where Hello.class is there i am getting,

Error: Could not find or load main class com.util.Hello and not able to proceed further.

can some one help me in this issue?

Answer 1

navigate to /home/scripts using terminal

javac com/util/Hello.java 

then

cd /home/scripts
java -cp . com.util.Hello

Or,

java -cp "/home/scripts" com.util.Hello

At first you must generate your .class file :

javac ./hello.java

This command has generated hello.class file And after you can run your class file ! :)

java hello
