I know that we can load classes dynamically by using custom class loaders.
But here my problem is my Class itself is depends upon other classes

My task is to get PigServer object .So I have used following code to load PigServer class

_pigServerClass = _classLoader.loadClass("org.apache.pig.PigServer");

But here PigServer class itself is depends upon so many other classes.

So when i am trying to get instance of PigServer class then it is showing following errors

java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory
java.lang.ClassNotFoundException:org.apache.log4j.AppenderSkeleton
 etc..

Can anyone tell how to solve this?

    How you created your ClassLoader?

    Did you specified another “parent” classloader, on wich classloading can be delegated?
