I had started about learning clojure and though the REPL interpreter seems to be the standard way of starting learning, I wanted to do it in a more Test driven method using maven. So I created a source and test directory and went about writing a simple learn.clj and a simple testlearn.clj. Took some time to figure things out and make the tests work Here is the directory structure  (Learn.clj dir structure \NetBeans2\ClojureLearn2\src\main\clojure\my\clojure\learn.clj) (ns my.clojure.learn  (:gen-class)) (defn main  [args]   (println  "A red apple tree" )    (println (def x(str "Hello " args "!")) )    x  ) (defn add [x y]     (+ x y) ) ( defn workingwithlist []   (println "In the function workingwithlist")   (def listx (list 1 (add 1 1) 3 4  ))    (doseq [item listx]    (println item))      listx   )  (TestLern.clj dir s...

First you need to boot from the hard drive For that put the harddrive in an hardrive enclosure and connect it via usb to your host OS Then follow the steps in the Virtual box help guide 9.9.1. Access to entire physical hard disk While this variant is the simplest to set up, you must be aware that this will give a guest operating system direct and full access to an entire physical disk. If your host operating system is also booted from this disk, please take special care to not access the partition from the guest at all. On the positive side, the physical disk can be repartitioned in arbitrary ways without having to recreate the image file that gives access to the raw disk. To create an image that represents an entire physical hard disk (which will not contain any actual data, as this will all be stored on the physical disk), on a Linux host, use the command VBoxManage internalcommands createrawvmdk -filename /path/to/file.vmdk -rawdisk /dev/sda This creates the ima...

Got the tip from http://mx4j.sourceforge.net/docs/api/mx4j/tools/remote/PasswordAuthenticator.html ----------------------------------------- echo("\nCreate an RMI connector client and " + "connect it to the RMI connector server"); JMXServiceURL url = //new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi"); new JMXServiceURL("service:jmx:rmi:///jndi/rmi://11.11.11.11:711/jmxrmi"); String[] credentials = new String[2]; // The user will travel as clear text credentials[0] = "user"; //user name credentials[1] = "password"; //password Map environment = new HashMap(); environment.put(JMXConnector.CREDENTIALS, credentials); JMXConnector jmxc = JMXConnectorFactory.connect(url, environment);

Here are the steps I followed to do this Prerequisite - A working knowledge of maven is a must - Some knowledge of using Xbean is good ( not a must) Creating a BC 1.
