Hi:
Everybody. I meet a problem when i try to locking a file using java
class: FileChannel and FileLock. The file located in a sharing
directory of a smb server mounted to a local file system. I use the
mac os X 10.3.3.
The souce code showed as following:
RandomAccessFile raf =
new RandomAccessFile(parametersPath+"lock.dat", "rw");
FileChannel channel = raf.getChannel();
FileLock lock = channel.lock();
When program executed to channel.lock(), java throw a IOException:
Operation not supported.
I never met the problem when i run the codes on the windows or linux.
And it never happended when i lock a local file! So i think it is a
java problem of file locking on network filesystem of Mac OS. I have
found some document about the smb file lock on Mac OS X. But they are
not relevant to java.
I guess one possibility is the mount_smbfs mode of Mac OS. Or Mac OS
do not support the file locking of network filesystem.
Is there anybody met the same problem? i have tired about it.
Thanks!
Regards
Lucas
