in Java J2EE I know how frustrating is to see Exception in thread "main" java.lang.NoClassDefFoundError,which is a manifestation of NoClassDefFoundError in Java. I have seen it a http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html couple of times and spent quite a lot time initially to figure out what is wrong, which class is missing etc. The first mistake I did was mingling java.lang.ClassNotfoundException and NoClassDefFoundError, in reality, they are totally different, and my second mistake was using trial and error method to solve this java.lang.NoClassDefFoundError instead of understanding why NoClassDefFoundError is coming, what is error in the real reason behind NoClassDefFoundError and how to resolve this. In this Java tutorial, I have tried to rectify that mistakes and uncover some secrets of NoClassDefFoundError in Java and will share my experience around it. NoClassDefFoundError is not something which cannot be resolved or hard to resolve it's just its manifestation which puzzles most of Java developer. This is error in java the most common error in Java development along with java.lang.OutOfMemoroyError: Java heap space and java.lang.OutOfMemoryError: PermGen space Anyway lets's see Why NoClassDefFoundError comes in Java and what to do to resolve NoClassDefFoundError in Java. What is the reason of NoClassDefFoundError in Java? NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available at compile time. For example, if we have a method call from a class or accessing any static member of a Class and that class is not available during run-time then JVM will throw NoClassDefFoundError. It's important to understand that this is different than ClassNotFoundException which comes while trying to load a class at run-time only and the name was provided during runtime, not at compile-time. Many Java developer mingles this two Error and gets confused. In short, NoClassDefFoundError will come if a class was present during compile time but not available in java classpath during runtime. Normally you will see below line in log when you get NoClassDefFoundError: Exception in thread "main" java.lang.NoClassDefFoundError Excepti
