Are you expecting to see specific names of the features? DescribeDB
should just be listing the general feature names. Mine does this.

If you want to inspect specific files, you can use the
com.bbn.openmap.layer.vpf.Server class, that should provide more
specific information in the files.

Are you looking for the attribute names for the specific features?
VMap2Shape doesn't create dbf files that would hold that information,
it's a simple program that just pulls geometries out of the database.
