Class SmbFile

Direct Known Subclasses:
SmbNamedPipe

public class SmbFile extends URLConnection
This class represents a resource on an SMB network. Mainly these resources are files and directories however an SmbFile may also refer to servers and workgroups. If the resource is a file or directory the methods of SmbFile follow the behavior of the well known File class. One fundamental difference is the usage of a URL scheme [1] to specify the target file or directory. SmbFile URLs have the following syntax:
     smb://[[[domain;]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
URLDescription
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 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.

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.

      The canonicalized URL of this SMB resource.
    • getShare

      public String getShare()
      Retrieves the share associated with this SMB resource. In the case of smb://, smb://workgroup/, and smb://server/ URLs which do not specify a share, null will be returned.
      Returns:
      The share component or null if there is no share
    • getServer

      public String getServer()
      Retrieve the hostname of the server for this SMB resource. If this SmbFile references a workgroup, the name of the workgroup is returned. If this SmbFile refers to the root of this SMB network hierarchy, null is returned.

    • exists

      public boolean exists() throws SmbException
      Tests to see if the SMB resource exists. If the resource refers only to a server, this method determines if the server exists on the network and is advertising SMB services. If this resource refers to a workgroup, this method determines if the workgroup name is valid on the local SMB network. If this SmbFile refers to the root smb:// resource true is always returned. If this SmbFile is a traditional file or directory, it will be queried for on the specified server as expected.

      Throws:
      SmbException
    • canWrite

      public boolean canWrite() throws SmbException

      public long createTime() throws SmbException
      Retrieve the time this SmbFile was created. The value returned is suitable for constructing a Date object (i.e. seconds since Epoch 1970). Times should be the same as those reported using the properties dialog of the Windows Explorer program. For Win95/98/Me this is actually the last write time. It is currently not possible to retrieve the create time from files on these systems.

    • listFiles

      public SmbFile[] listFiles() throws SmbException
      List the contents of this SMB resource as an array of SmbFile objects. This method is much more efficient than the regular list method when querying attributes of each file in the result set.

      The list of SmbFiles returned by this method will be;

      • files and directories contained within this resource if the resource is a normal disk file directory,
      • all available NetBIOS workgroups or domains if this resource is the top level URL smb://,
      • all servers registered as members of a NetBIOS workgroup if this resource refers to a workgroup in a smb://workgroup/ URL,

      • or null if the resource cannot be resolved.
      Returns:
      An array of SmbFile objects representing file and directories, workgroups, servers, or shares depending on the context of the resource URL
      Throws:
      SmbException
    • listFiles

      public SmbFile[] listFiles(String wildcard) throws SmbException
      The CIFS protocol provides for DOS "wildcards" to be used as a performance enhancement. The client does not have to filter the names and the server does not have to return all directory entries.

      The wildcard expression may consist of two special meta characters in addition to the normal filename characters. The '*' character matches any number of characters in part of a name. If the expression begins with one or more '?'s then exactly that many characters will be matched whereas if it ends with '?'s it will match that many characters or less.

      Wildcard expressions will not filter workgroup names or server names.

      Changes the name of the file this SmbFile represents to the name designated by the SmbFile argument.

      Remember: SmbFiles are immutible and therefore the path associated with this SmbFile object will not change). To access the renamed file it is necessary to construct a new SmbFile.

      Parameters:
      dest - An SmbFile that represents the new pathname
      Throws:
      NullPointerException - If the dest argument is null
      SmbException
    • copyTo

      public void copyTo(SmbFile dest) throws SmbException
      This method will copy the file or directory represented by this SmbFile and it's sub-contents to the location specified by the dest parameter. This file and the destination file do not need to be on the same host. This operation does not copy extended file attibutes such as ACLs but it does copy regular attributes as well as create and last write times. This method is almost twice as efficient as manually copying as it employs an additional write thread to read and write data concurrently.

      It is not possible (nor meaningful) to copy entire workgroups or servers.

      Parameters:
      dest - the destination file or directory
      Throws:
      SmbException
    • delete

      public void delete() throws SmbException
      This method will delete the file or directory specified by this SmbFile. If the target is a directory, the contents of the directory will be deleted as well.

      Throws:
      SmbException
    • length

      public long length() throws SmbException
      Returns the length of this SmbFile in bytes. If this object is a TYPE_SHARE the total capacity of the disk shared in bytes is returned. If this object is a directory or a type other than TYPE_SHARE, 0L is returned.

      SmbException
    • setCreateTime

      public void setCreateTime(long time) throws SmbException
      Set the create time of the file. The time is specified as milliseconds from Jan 1, 1970 which is the same as that which is returned by the createTime() method.

      Throws:
      SmbException
    • setReadOnly

      public void setReadOnly() throws SmbException
      Make this file read-only. This is shorthand for setAttributes( getAttributes() | ATTR_READ_ONLY ).
      Throws:
      SmbException

      A new URL for this SmbFile
      Throws:
      MalformedURLException
    • hashCode

      public int hashCode()
      Computes a hashCode for this file based on the URL string and IP address if the server. The hashing function uses the hashcode of the server address, the canonical representation of the URL, and does not compare authentication information.

    • equals

      public boolean equals(Object obj)
      Tests to see if two SmbFile objects are equal. Two SmbFile objects are equal when they reference the same SMB resource. More specifically, two SmbFile objects are equals if their server IP addresses are equal and the canonicalized representation of their URLs, minus authentication parameters, are case insensitivly and lexographically equal.

      For example, assuming the server angus resolves to the 192.168.1.15 IP address, the below URLs would result in SmbFiles that are equal.

       smb://192.168.1.15/share/DIR/foo.txt

      Throws:
      IOException
    • getShareSecurity

      public ACE[] getShareSecurity(boolean resolveSids) throws IOException
      Return an array of Access Control Entry (ACE) objects representing the share permissions on the share exporting this file or directory. If no DACL is present, null is returned. If the DACL is empty, an array with 0 elements is returned.

      Note that this is different from calling getSecurity on a share. There are actually two different ACLs for shares - the ACL on the share and the ACL on the folder being shared. Go to Computer Management > System Tools > Shared Folders invalid input: '&gt' Shares and look at the Properties for a share. You will see two tabs - one for "Share Permissions" and another for "Security". These correspond to the ACLs returned by getShareSecurity and getSecurity respectively.

      Parameters:
      resolveSids - Attempt to resolve the SIDs within each ACE form their numeric representation to their corresponding account names.
      Throws:
      IOException

      public ACE[] getSecurity() throws IOException
      Return an array of Access Control Entry (ACE) objects representing the security descriptor associated with this file or directory.

      Initially, the SIDs within each ACE will not be resolved however when getType(), getDomainName(), getAccountName(), or toString() is called, the names will attempt to be resolved. If the names cannot be resolved (e.g. due to temporary network failure), the said methods will return default values (usually S-X-Y-Z strings of fragments of).

      Alternatively getSecurity(true) may be used to resolve all SIDs together and detect network failures.

      Throws:
      IOException
