If you are facing java.lang.NoClassDefFoundError, which means the Class Loader file responsible for dynamically loading classes can not find the .class file. So to remove this error, you should set your classpath to the location where your Class Loader is present.

Hope it helps!!

NoClassDefFoundError means that the class is present in the classpath at Compile time, but it doesn't exist in the classpath at Runtime.

If you're using Eclipse, make sure you have the shapes, linepoints and the spaceobjectsas entries in the .classpath file.

Hi, i'm currently using Eclipse.

I can build and compile the project but at runtime i get the following error:

java.lang.NoClassDefFoundError: oracle/security/restsec/jwt/JwtToken

I have added the jar files accordingly. But the error still pops up.

Can you share the code snippet that you are using?
