title: What is the use of Custom Class Loader
body: <p>Recently I came accross the java custom class loader api. I found one use over here, <a href="http://kamranzafar.org/weblog/2006/12/25/loading-classes-directly-from-jar-files/" rel="noreferrer">kamranzafar's blog</a>
  I am a bit new to the class loader concept. Can any one explain in detail, what are the different scenarios where we may need it or we should use it?</p>
