the class ClassLoaderTest method main.

public static void main(String[] args) throws Exception {
    File file = new File(BASE);
    URL[] urls = new URL[1];
    urls[0] = file.toURI().toURL();
    URLClassLoader ucl = new URLClassLoader(urls);
    Class<?> c = ucl.loadClass("MyTransform");
    Constructor<?> cons = c.getConstructor(new Class[] {});
    Object o = cons.newInstance();
    // it again and catching an AlgorithmAlreadyRegisteredExc
    try {
        Transform.register(MyTransform.URI, "MyTransform");
        throw new Exception("ClassLoaderTest failed");
    } catch (AlgorithmAlreadyRegisteredException e) {
    // test passed
    }
}
