How can I mount a windows drive in Java?

Question

I'm trying to get all data exist in ipconfig /all for a specific interface.

I can not use netssh, or any other program.

I can use grep(for windows - but only grep, not mgrep pcgrep or whatever), sed (same thing..) or findstr of course.

Can you guys think of a way?

I want to get all the data for "SLOT 2 3" and loose all the other data.

This is what the output looks like:

Solution 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}]

Solution 2

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.

Solution 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) {
    }

If the user has already mapped drive f: you would get the "System error 85 has occurred." in the process output. You can just scan for it.

Directly using net.exe does not handle error cases and is not platform neutral.

@munsingh: He asked for Windows. Who cares for cross platform

After the mounting, we can perform operations on the directory using normal FS commands right? Can you add an example to read a file? When I do Path share = Paths.get(new URI("f:\")); i get an error Provider "f" not installed.
