Java main class extending another one

Question

I'm having a problem compiling and running the Java class containing my main method. My code is similar to:

public import myLib.LibClass;

public class MyMainClass extends LibClass{

    public static void main(String[] args) {
        ...
    }
    @override
    public void LibClassFunction(){...}
}

In which LibClass is an abstract class coming from an already compiled .jar file, of which I have to implement a specific abstract function. I can compile without problems with

javac -cp ./myLib.jar MyMainClass.java

However, I'm not managing to run it with the "java" command, getting the error Error: Could not find or load main class MyMainClass, even if MyMainClass doesn't have any package.

Thank you in advance!

Answer 1

The command line you need is

java -cp myLib.jar:. MyMainClass

You need to provide the stuff that your class depends on.

Separator should be ;, not :, on Unix, Linux, HP-UX, AIX, Solaris, etc.
