How to tell if a directory is remotely mounted using Java

Question

Is there a way to determine programatically if a particular directory is actually remotely mounted? Can this be done with Java, and if not can it be done with native C code over JNI? Since this is Java it could be running under Linux or Windows or Mac, so a proper solution needs to address all these platforms. (Again if its multiple separate solutions with C over JNI thats ok). And there may be different cases like with NFS or samba or anything else. Thanks.

Accepted Answer

for Linux, and possibly Macintosh, you can use system library through JNI. The relevant system call is `getmntent`, described here.

There is a field in `mntent` you can use to check to see if mount point is from device or a server, `mnt_fsname`, in a similar field you can get filesystem type, `mnt_type"
