How to load JAR files dynamically at Runtime?

Question

Why is it so hard to do this in Java? If you want to have any kind of module system you need to be able to load JAR files dynamically. I\'m told there\'s a way of doing it b

Answer 1

This can be a late response, I can do it as this (a simple example for fastutil-8.2.2.jar) using jhplot.Web class from DataMelt (http://jwork.org/dmelt)

import jhplot.Web;
Web.load("http://central.maven.org/maven2/it/unimi/dsi/fastutil/8.2.2/fastutil-8.2.2.jar"); // now you can start using this library

According to the documentation, this file will be download inside "lib/user" and then dynamically loaded, so you can start immediately using classes from this jar file in the same program.
