Java.lang.noclassdeffounderror In Eclipse At Runtime

Your code wouldn't compile if the required classes weren't present (unless classes are loaded with reflection), so usually this exception means that your classpath doesn't include the required classes. I have tried also setting the classpath and the sourcepath.If you have any further insight that would be gratefully appreciated. option from the same directory where you have HelloWorld class file. When i tried using hello it worked like magic.

  5. So I would like to add that, not having package directive can also lead to class not found errors.
  6. Any suggestions Quote -1 #101 Toughs 2012-04-11 12:32 set classpath=%classpath%;.; Worked!
  7. I remove it and viola!

Hello Iam getting the following error when im compiling a junit testing programF:\junit4.10>javac check4PrimeTest.javacheck4PrimeTest.java:4: cannot find symbolsymbol : class check4Primelocation: class check4PrimeTestprivate check4Prime check4prime=new check4Prime(); ^check4PrimeTest.java:4: cannot find symbolsymbol : class So, the circumstances leading to a NoClassDefFoundError are relatively simple, and once you understand that it is different from the ClassNotFoundException the solution can also be relatively simple: Put the class Hot Network Questions How long could the sun be turned off without overly damaging planet Earth + humanity?

Right click on your project and select -> Compile Module, and then re-start the project and it should work again. What it means by saying "available in compile time"?

First, we define a Test class with a simple constructor:Test.java: public class Test { public Test() { System.out.println("A new instance of the Test class was created!"); } } Then, we define Java.lang.classnotfoundexception Eclipse Junit I have seen it a couple of times and spent quite a lot time initially to figure out what is wrong, which class is missing etc. help.

The most common mistake is not to include all the necessary classes, before starting to execute a Java application that has dependencies on some external libraries. If you are working in J2EE environment than the visibility of Class among multiple Classloader can also cause java.lang.NoClassDefFoundError, see examples and scenario section for detailed discussion. share|improve this answer answered Jul 31 '13 at 15:03 sschrass 3,81342044 4 How to do that? –King Sep 28 '15 at 7:30 add a comment| up vote 4 down vote Noclassdeffounderror Vs Classnotfoundexception Also, it is important to mention that the definition of the class existed when the application code was compiled, but the definition can no longer be found in the runtime.
