Jersey REST The ResourceConfig instance does not contain any root resource classes?

I found another reason Jersey could fail to find a root resource. The error message is the same, so I thought it'd be a good reason to document the root cause here in case other people stumble on it.

I found that the "no provider classes found" message is scary but not important.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
