Java just isn't seeing it.  You have the ".class" file in the wrong subdirectory.

The underlying error is that 'FooConstants' is not in the correct place in the classpath.  It is not Java's fault.

Instead of providing us with a partial clue (that never contains the whole answer and sometimes contains none of it), put together a Simple, Self-Contained Compilable Example (SSCCE):

http://sscce.org/

What you will find is that the class 'FooConstants' is not in the directory location in the classpath that corresponds to its package.

Show us the source for 'FooConstants', please (no more snippets!) and in what directory it resides within the JAR ("jar tf jarfile | grep FooConstants" being a convenient way to figure that out).
