Java How to load classes from jar in classpath using Class ClassLoader (no URLClassLoader)?

JAR should not be in your CLASSPATH.

This works fine: I have a JDOM JAR in my CLASSPATH.

public class ClassLoaderDemo {
    public static void main(String[] args) {
        try {
            ClassLoader classLoader = ClassLoaderDemo.class.getClassLoader();
            if (classLoader != null) {
                Class clazz = classLoader.loadClass("org.jdom.Document");
                System.out.println(clazz.getName());
            }
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}
