Error: integrity constraint violation

Hello, folks:

I am new to ManifoldCF, and trying to make my own connector.
For now, I could successfully build ManifoldCF including my own connector.
However, when I tried to run, I have exceptions.

The exception I am facing is :

org.apache.manifoldcf.core.interfaces.ManifoldCFException: integrity

I am guessing my class-path would have a problem, but do not have a
confidence.
What is the cause of this error?

I would appreciate for any of your help.


Sincerely,
Kaya
