Is there a flat files JDO implementation?

I have a simple app I'd like to use JDO. But I don't want to use any DB back, just regular file system. Before jdo, I had this class it serializes it object to a file whereas file name is the "primary key". I'd like to be able to do the same thing with JDO. Is that possible?

Perhaps DataNucleus is a choice for you as it supports different kind of storage backends. The xml storage plugin or the embedded database db4o storage plugin might be an option, but both use a single file for all objects instead of one file per object.

Some time ago I used the JDO 1.0.1 file implementation and worked fine for my simple cases

Reference Implementation for JDO 1.0 used flat files. Look at Apache JDO which ought to contain the original files
