Figured out the hibernate problem. Foolishness on my part. ContentBeanImpl was missing a

default constructor.  Minor mods to the mapping file to fix my self made difficulty.  AVMNodeFactory
now does the right thing with hibernate proxies.  Test now extends to creating a file in
a directory in a repository.
