If there's no package then go to folder containing class and say java -cp .

Depending on how you start your application, you need to revise the argument to -cp, your Class-Path entry in MANIFEST.MF or your disk layout. share|improve this answer answered Jul 1 '13 at 16:02 Thorbjørn Ravn Andersen 50k15116244 11 Can you please be more eclipse specific?

in Java What is ClassNotFoundException in Java ClassNotFoundException is one of Java nightmare every Java developer face in there day to day life. java.lang.NoClassDefFoundError and java.lang.ClassNotFoundException are two errors which occurs by and now and chew up of your precious time while finding classnotfoundexception java 8 and fixing root cause. From the name java.lang.ClassNotFoundException looks quite simple but underlying cause of

java, what is real cause of itand how to fix it along with some more frequent and infamous examples of java.lang.ClassNotFoundException in Java or J2EE,Don'tmistake this exception with NoClassDefFoundError in Java which is also due to incorrect classpath http://stackoverflow.com/questions/17408769/how-do-i-resolve-this-java-class-not-found-exception in Java. Though both of them are related to missing class file when Java tries to load class in Java they are completely different to each other. Correct understanding of When class is loaded in Java and How Classpath works is must to troubleshoot and fix this error quickly. What is java.lang.classNotFoundException in Java As the name suggests classNotFoundException in Java is a subclass of java.lang.Exception and Comes when Java Virtual Machine tries to load http://javarevisited.blogspot.com/2011/08/classnotfoundexception-in-java-example.html a particular class and doesn't found the requested class in classpath. Another important point about this Exception is that, It is a checked Exception and you need to provide explicitly Exception handling while using methods which can possibly throw classnotfoundexception in java either by using try-catch block or by using throws clause. Though underlying concept of this exception is simple but it always manifest itself in such format that you need to spend some time to figure out what exactly wrong with your classpath. If you want to know nasty secrets of java classpath which can cause issue see the link. When ClassNotFoundException occurs in Java: As per java doc java.lang.classNotFoundException comes in following cases: 1) When we try to load a class by using Class.forName() method and .class file or binary of class is not available in classpath. 2) When Classloader try to load a class by using findSystemClass () method. 3) While using loadClass() method of class ClassLoader in Java. These statements are completely true in terms of theory of ClassNotFoundExcepiton in Java but as per my experience the concept is "ClassNotFoundException will come only when JVM tries to load a class at run-time, nothing related to compile time unlike NoClassDefFoundError". Also since till run time JVM doesn't know about this Class it can only be done by above specified metho

It will provide you with an overview of this common Java exception, a sample Java program to not found exception support your learning process and resolution strategies. If you are interested on more advanced class loader related problems, I recommended that you review my article series on java.lang.NoClassDefFoundErrorsince these Java exceptions are closely related.java.lang.ClassNotFoundException: Overview As per the Oracle documentation, ClassNotFoundExceptionis thrown following the failure of a class loading call, using its string name, as per below:The Class.forName methodThe ClassLoader.findSystemClass methodThe ClassLoader.loadClass method In other words, it means that one particular Java class was not found or could not be loaded at “runtime” from your application current context class loader. This problem can be particularly confusing for Java beginners. This is why I always recommend to Java developers to learn and refine their knowledge on Java class loaders. Unless you are involved in dynamic class loading and using the Java Reflection API, chances are that the ClassNotFoundException error you are getting is not from your application code but from a referencing API. Another common problem pattern is a wrong packaging of your application code. We will get b
