For instance, you have to call your class from the root bin folder with the full package name (ie. my.package.myClass). I'd be more specific if I could how to resolve noclassdeffounderror in java but I'm not much of a java guy. I just remember messing this up a few times. –frank hadder Aug 29 '08 at 15:06 14 @BoltClock We need a canonical question to point the numerous duplicates to.

Look for differences in your build time and runtime classpaths. share|improve this answer answered Aug 29 '08 at 15:01 Mocky 4,10752023 1 I had this error happen when putting a source file under the wrong namespace/package. I figured I could just put it anywhere, and the compiler was happy. Turns out I should have been more diligent for runtime to be happy as well. –CenterOrbit Oct 21 '14 at 15:34 I had this error once when my server ran out of memory during a file upload. Every time I tried the upload, I'd get a different error. Eventually it told me I did
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 couple of times and spent quite a lot time initially
Noclassdeffounderror Vs Classnotfoundexception
to figure out what is wrong, which class is missing etc. The first mistake noclassdeffounderror android studio I did was mingling java.lang.ClassNotfoundException and NoClassDefFoundError, in reality, they are totally different, and my second mistake was using trial and java.lang.noclassdeffounderror wrong name error method to solve this java.lang.NoClassDefFoundError instead of understanding why NoClassDefFoundError is coming, what is the real reason behind NoClassDefFoundError and how to resolve this. In this Java tutorial, I have tried to rectify that http://stackoverflow.com/questions/34413/why-am-i-getting-a-noclassdeffounderror-in-java 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 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 http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html 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 Exception in thread "main" simply indicate that its "main" thread which is not able to find a particular class it could be any thread so just don't worry. The difference between this error coming in the main thread and another thread is when Exception in thread "main" comes program crashes or shut itself down as opposed to other thread in which
