About HttpComponents Core - The HttpCore components implement the most fundamental aspects of the HTTP protocol. They are nonetheless sufficient to develop basic client side and server side HTTP services with a minimal footprint and no external dependencies. HttpCore NIO extensions can be used to build asynchronous HTTP services based on non-blocking I/O model capable of handling a great number of simultaneous connections with just a few I/O threads. HttpCore will form the foundation of the future releases of Jakarta HttpClient.

Commons VFS provides a single API for accessing various different file systems. It presents a uniform view of the files from various different sources, such as the files on local disk, on an HTTP server, or inside a Zip archive. For example, you can use filenames like "tar:gz:http://anyhost/dir/mytar.tar.gz!/mytar.tar!/path/in/tar/README.txt" to access a compressed tar file located on a web server.

Commons VFS 1.0 is the first release
