Hi,

Here, a simple example using the Samba Java CIFS Client Library. JCIFS is an Open Source client library that implements the CIFS/SMB networking protocol in 100% Java. CIFS is the standard file sharing protocol on the Microsoft Windows platform (e.g. Map Network Drive …). This client is used extensively in production on large Intranets.
