Jar Class Loader, a configurable and dynamic custom classloader designed to create, manage and manipulate isolated Java classloaders in IoC frameworks and web applications.

public JarClassLoader(URL url) { super(new URL[] { url }); this.url = url; } jar:http://www.example.com/jarfile.jar!/mypackage/myclass.class. The first line in the getMainClassName method is: URL u = new URL ("jar", "", url + "!/"); This statement constructs a new URL object representing a JAR URL, appending the !/ separator to the URL that was used in creating the JarClassLoader instance. The JarRunner application consists of two classes, JarRunner and JarClassLoader.

The JarClassLoader class extends java.net.URLClassLoader.As its name implies, URLClassLoader is designed to be used for loading classes and resources that are accessed by searching a set of URLs. The URLs can refer either to directories or to JAR files. In addition to subclassing URLClassLoader, JarClassLoader also makes use of features in two other new JAR-related APIs, the java.util.jar

So in order to cast/clone the objects, JclUtils class is used as shown in the example below: JarClassLoader jcl = new JarClassLoader(); jcl.add("myapi-impl.jar"); //Load jar file //Create default factory JclObjectFactory factory = JclObjectFactory.getInstance(); //Create object of loaded class Object obj = factory.create(jcl,"myapi.impl.MyInterfaceImpl"); //Obtain interface reference in the current classloader MyInterface mi = JclUtils.cast(obj, MyInterface.class); //Convert the object into jar:http://www.example.com/jarfile.jar!/mypackage/myclass.class The first line in the getMainClassName method is: URL u = new URL("jar", "", url + "!/"); This statement constructs a new URL object representing a JAR URL, appending the !/ separator to the URL that was used in creating the JarClassLoader instance.
