Hmm, it's hard to tell what the cause might be. It's been a while since I've really used java.io seriously, but I'm wondering if it's a file access problem, e.g.g the files is read only, the file is currently in use and so it's locked.

I agree with Mark 'coz I tried to update a jar file with the same command. It's working fine!! So, I think the problem with the permission only.
I agree. Here's the link:
