The first public release (0.1) of GaeVFS is now available: http://gaevfs.appspot.com/
GaeVFS is a plug-in for Apache Commons VFS that implements a virtual file system on top of the Google App Engine for Java (GAE) datastore. It provides a writeable file system for GAE, since GAE does not allow writing to the local file system. GaeVFS is licensed under the Apache License, Version 2.0. GaeVFS includes a servlet (GaeVfsServlet) that allows you to: - upload files into GaeVFS - serve files from GaeVFS - (optionally) perform GaeVFS directory listings The goal of GaeVFS is to provide a portability layer that allows you to write application code to access the file system (both reads and writes) that runs unmodified in either the GAE or "traditional" Java servlet environments. Please let me know if you find this useful.
