A free alternative to DB4Os ObjectManager or OME (Object Manager Enterprise). Allows you to view and edit all objects stored in a DB4O database. The old ObjectManager 6.4 could no longer be used on new databases, and the new OME has crippling bugs.
We have released the code as open source project on Sourceforge.
It is imperative that you read the README.txt and make the adjustments described there, or the DB4O Viewer will not work properly.
