Java Exception: java.lang.NoSuchFieldError

Issue:

When you access static constant in your program, especially in Web app, you may found that some of static field cannot be access. You will get java.lang.NoSuchFieldError exception.

Reason:

This exception is usually happened when you build your class into a jar. But you were trying to access same class from Class folder. So JVM may be confused. It might read wrong class which is not contains your field.

Solution:

Double check if there is a duplicate class defined in Jar. And remove one of duplicate class from your app.
