com.knowgate.jcifs.smb.SmbFile

main;]username[:password]@]server[:port]/[[share/[dir/]file]]][?[param=value[param2=value2[...]]] This example:

 smb://storage15/public/foo.txt

would reference the file foo.txt in the share public on the server storage15. In addition to referencing files and directories, jCIFS can also address servers, and workgroups.

Important: all SMB URLs that represent workgroups, servers, shares, or directories require a trailing slash '/'.

When using the java.net.URL class with 'smb://' URLs it is necessary to first call the static jcifs.Config.registerSmbURLHandler(); method. This is required to register the SMB protocol handler.

The userinfo component of the SMB URL (domain;user:pass) must be URL encoded if it contains reserved characters. According to RFC 2396 these characters are non US-ASCII characters and most meta characters however jCIFS will work correctly with anything but '@' which is used to delimit the userinfo component from the server and '%' which is the URL escape character itself.

The server component may a traditional NetBIOS name, a DNS name, or IP address. These name resolution mechanisms and their resolution order can be changed (See Setting Name Resolution Properties). The servername and path components are not case sensitive but the domain, username, and password components are. It is also likely that properties must be specified for jcifs to function (See Setting JCIFS Properties). Here are some examples of SMB URLs with brief descriptions of what they do:

[1] This URL scheme is based largely on the SMB Filesharing URL Scheme IETF draft.

SMB URL Examples
URL	Description
`smb://users-nyc;miallen:mypass@angus/tmp/`	This URL references a share called `tmp` on the server `angus` as user `miallen` who's password is `mypass`.
`smb://Administrator:P%40ss@msmith1/c/WINDOWS/Desktop/foo.txt`	A relativly sophisticated example that references a file `msmith1`'s desktop as user `Administrator`. Notice the '@' is URL encoded with the '%40' hexcode escape.
`smb://angus/`	This references only a server. The behavior of some methods is different in this context(e.g. you cannot `delete` a server) however as you might expect the `list` method will list the available shares on this server.
`smb://myworkgroup/`	This syntactically is identical to the above example. However if `myworkgroup` happends to be a workgroup(which is indeed suggested by the name) the `list` method will return a list of servers that have registered themselves as members of `myworkgroup`.
`smb://`	Just as `smb://server/` lists shares and `smb://workgroup/` lists servers, the `smb://` URL lists all available workgroups on a netbios LAN. Again, in this context many methods are not valid and return default values(e.g. `isHidden` and `renameTo` will always return false).
`smb://angus.foo.net/d/jcifs/pipes.doc`	The server name may also be a DNS name as it is in this example. See Setting Name Resolution Properties for details.
`smb://192.168.1.15/ADMIN$/`	The server name may also be an IP address. See Setting Name Resolution Properties for details.
`smb://domain;username:password@server/share/path/to/file.txt`	A prototypical example that uses all the fields.
`smb://myworkgroup/angus/ <-- ILLEGAL`	Despite the hierarchial relationship between workgroups, servers, and filesystems this example is not valid.
`smb://server/share/path/to/dir <-- ILLEGAL`	URLs that represent workgroups, servers, shares, or directories require a trailing slash '/'.
`smb://MYGROUP/?SERVER=192.168.10.15`	SMB URLs support some query string parameters. In this example the `SERVER` parameter is used to override the server name service lookup to contact the server 192.168.10.15 (presumably known to be a master browser) for the server list in workgroup `MYGROUP`.

A second constructor argument may be specified to augment the URL for better programmatic control when processing many files under a common base. This is slightly different from the corresponding java.io.File usage; a '/' at the beginning of the second parameter will still use the server component of the first parameter. The examples below illustrate the resulting URLs when this second contructor argument is used.

Examples Of SMB URLs When Augmented With A Second Constructor Parameter
First Parameter	Second Parameter	Result
`smb://host/share/a/b/`	`c/d/`	`smb://host/share/a/b/c/d/`
`smb://host/share/foo/bar/`	`/share2/zig/zag`	`smb://host/share2/zig/zag`
`smb://host/share/foo/bar/`	`../zip/`	`smb://host/share/foo/zip/`
`smb://host/share/zig/zag`	`smb://foo/bar/`	`smb://foo/bar/`
`smb://host/share/foo/`	`../.././.././../foo/`	`smb://host/foo/`
`smb://host/share/zig/zag`	`/`	`smb://host/`
`smb://server/`	`../`	`smb://server/`
`smb://`	`myworkgroup/`	`smb://myworkgroup/`
`smb://myworkgroup/`	`angus/`	`smb://myworkgroup/angus/ <-- ILLEGAL (But if you first create an SmbFile with 'smb://workgroup/' and use and use it as the first parameter to a constructor that accepts it with a second String parameter jCIFS will factor out the 'workgroup'.)`

Instances of the SmbFile class are immutable; that is, once created, the abstract pathname represented by an SmbFile object will never change. @see java.io.File
