Does Berkeley DB java edition, support saving vectors

Question

I am getting the following stack trace. Just want to know what your first impression is. Does it seem to be saying that Vectors cannot be saved to the Berkeley DB. What else can I provide you with, that will help work this out.

You probably need to serialize your data before passing them to Berkeley DB for storage.
