Removing file locks in Windows and Java

Question
I have a Java program that opens a file using the RandomAccessFile class.
I'd like to be able to rename that file while it is opened by Java. In Unix, this isn't a problem. Does anyone know how I can do this in Windows?
Should I set Java to open it a certain way?
Thanks in advance.
Edit, clarification: I'd like to be able to set this file sharing access in my Java code.
Solution
You need to close any handles on the file at any way. E.g. a FileOutputStream
on that File
must be closed before you can rename it. That's just the way how the Windows file system works.
OTHER TIPS
in_stream.close();
out_stream.getChannel().close();
out_stream.close();
Anyhow in Windows it stay locked :*(
