Removing file locks in Windows and Java

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 thi开发者_开发技巧s 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.

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.

in_stream.close();            
out_stream.getChannel().close();
out_stream.close();

Anyhow in Windows it stay locked :*(
