File Move throws IOException due to different mount volume in Linux

Hi my java program has to move the files to a folder which is in different mounted folder. I want to treat it as a normal folder path and move the file using

boolean success = file.renameTo(new File(dir, file.getName()));

it gives the status as false always and file not moved.

When I try with the filechannel.transferF开发者_如何学Crom(fcSource, 0, fcSource.size()); it is throwing IO Exception.

SEVERE 20110720 15.41.29 AccessLogProcessor:moveToArchive-File
    [/opt/apache2/logs/access_log.20110620.0015.tmp] move to
    [/opt/ahache2/logs/old] not success.. Try Special move with filechannel

     [/opt/apache2/logs/access_log.20110620.0015.tmp] failure
    ERROR:java.io.IOException: **No such file or directory

The destination folder in linux looks like normal and my id has no permission issue. The folder /opt/ahache2/logs/old is a mounted one.

About the 'renameTo' returning false, and according to the API:

Whether or not this method can move a file from one filesystem to another is platform-dependent. The return value should always be checked to make sure that the rename operation was successful.

So maybe you cannot use 'renameTo' to do what you want to do.
