JLAN Server is a high performance Java based file server supporting
Windows file sharing (SMB/CIFS), NFS and FTP protocols.
Write your own virtual filesystems with the core server handling all
protocol exchanges with the client to provide custom filesystems for
network and/or localhost access.
Version 3.5 adds the following new features:-
o Database Filesystem
The new DBDiskDriver filesystem accesses the database via a set of
interfaces, there is no embedded SQL or JDBC access in the main driver
class. A file loader interface provides the methods for the DBDiskDriver
to access the file data, which may allow direct access to the data or
load/save the data using a set of worker threads.
The main database access interfaces allow the filesystem structure and
file retention details to be stored in a database. Optinal interfaces
allow the background load/save request queue, file data and file id to
repository object id mapping to be contained within a database or
repository.
The release includes three database interface implementations that
provide support for mySQL, Oracle and Derby/Cloudscape databases.
There are file loader implementations included that allow the
files/folders to be stored on the local filesystem (SimpleFileLoader) or
using database BLOB fields to store the file data within the database
(DBFileLoader). There is also an abstract file loader that uses
filesystem file id to repository object id mapping that provides all of
the background load/save and caching support, only the loadFileData() and
saveFileData() methods need to be implemented.
o Win32 NetBIOS
The Win32 NetBIOS code now defaults to listening on all available LANAs,
and can recover from network adapters going offline/cable disconnected.
Also handles new LANAs coming online.
See the release notes for a more detailed list of the changes, at
http://www.starlasoft.com/jlansrv/release.html.
A fully working demo version of the server is available from the
Starlasoft web site at http://www.starlasoft.com.
A developer licence that includes the full source code, 12 months of
email support and 12 months of code updates is available. Royalty free
commercial licence also available.
