Examples of com.caucho.loader.EnvironmentClassLoader

com.caucho.loader.EnvironmentClassLoader
Class loader which checks for changes in class files and automatically picks up new jars.
DynamicClassLoaders can be chained creating one virtual class loader. From the perspective of the JDK, it's all one classloader. Internally, the class loader chain searches like a classpath.

    ServerSocket ss = null;
    Socket s = null;

      ss = new ServerSocket(0, 5, InetAddress.getByName("127.0.0.1"));
