A virtual drive plug-in is used by XXE to map an URL scheme (e.g. "
ftp") to a virtual drive. A virtual drive lets the user edit documents stored in places other than the local file system. This is done by emulating a hierarchical file system.
Some virtual drives have been implemented to access documents stored on an FTP server, WebDAV server, third-party content management systems, etc.
Like all plug-ins, a virtual drive plug-in is not declared anywhere. It is dynamically discovered and loaded during the startup of XXE (more info in Section 1, “Dynamic discovery of add-ons” in ) provided that it complies with the following conventions:
The code of the virtual drive plug-in must be contained in a JAR file having a name ending with "
This JAR file must contain a
META-INF/services/com.xmlmind.xmleditapp.vdrive.DriveFactory file containing the name of the class implementing interface
META-INF/services/com.xmlmind.xmleditapp.vdrive.DriveFactory which contains
