Is there any way to rename a file in a jar file?

I was wondering if there was any way to rename a file in a jar file without unzipping it or decompressing it.

Thanks.

Look at the nio classes in Java 1.7 There are new features that use the contents of a zip file like a file system.

Thanks.

But are there any examples you could give me?

sorry, I've only read the 1.7 features list:

I couldn't find any info about the Java nio classes.
Do you know anything?

Did you read all the sites at the page I gave the link to?

Thanks.
