How can I mount a windows drive in Java?

Question

We are working with some legacy code that accesses a shared drive by the letter (f:\ for example). Using the UNC notation is not an option. Our Java wrapper app will run as a service, and as the first step, I would like to map the drive explicitly in the code. Has anyone done this?

Answer 1

Consider executing the DOS command that maps a network drive as in the following code:

String command = "c:\\windows\\system32\\net.exe use f: \\\\machine\\share /user:user password";
Process p = Runtime.getRuntime().exec(command);
...

See details on net use command:

The syntax of this command is:


NET USE
[devicename | *] [\\computername\sharename[\volume] [password | *]]
        [/USER:[domainname\]username]
        [/USER:[dotted domain name\]username]
        [/USER:[username@dotted domain name]
        [/SMARTCARD]
        [/SAVECRED]
        [[/DELETE] | [/PERSISTENT:{YES | NO}]]

NET USE {devicename | *} [password | *] /HOME

NET USE [/PERSISTENT:{YES | NO}]

You can use JCIFS

http://jcifs.samba.org/src/docs/api/jcifs/smb/SmbFile.html

or if you want higher level API and support for other protocols like FTP, Zip and others:

http://commons.apache.org/vfs/filesystems.html

Both options are pure Java and cross platform.

Answer 3

I think the easiest way is to use the Runtime.getRuntime().exec() method and call the "net use" command.

For example:

    try {
        // Execute a command without arguments
        String command = "C:\\Windows\\system32\\net.exe use F: \\\\server\\share /user:user password";
        Process child = Runtime.getRuntime().exec(command);
    } catch (IOException e) {
    }
