PaderSyncFM is a file manager for BlackBerry, Java ME, and Android devices. It stands out from other file managers by providing access to FTP, SFTP, WebDAV, and SMB file servers. Moreover, the support for SOCKS, HTTP, HTTPS, and SSH protocols allows the application to cross network borders.
Dove is an application that facilitates the distribution of documents to a variety of destination types such as email, local files, FTP, FTPS, SFTP, TFTP, Samba servers, Windows network shared drives, and WebDAV servers. Being an abstraction layer over previously enumerated protocols, it allows sending of documents to email or to a WebDAV server with equal ease.
exJello is a JavaMail provider that connects to a Microsoft Exchange server (actually, it uses the WebDAV interface exposed by Outlook Web Access). It is designed as a drop-in replacement for the standard POP3 and SMTP providers. This allows you to send and receive messages through your Exchange server in situations where a POP3/SMTP interface is not available (through a restrictive firewall, for example, or if your administrator simply does not provide a POP3 or SMTP gateway).
Sardine is a next generation WebDAV client for Java. It is intended to be simple to use and does not implement the full WebDAV client spec. Instead, the goal is to provide methods for most use case scenarios when working with a WebDAV server. The code needs to run as fast as possible and use the latest released Apache HttpComponents.
