Is it possible to programatically get information about the JAR file
from which an application is being run?

I'm loading an application through Java Web Start and I'd like to be
able to determine:
1. the size of the JARS included with the application

<zen question>
Is that before they arrive, or after being cached? + *
</zen question>

2. the date they were packaged

* Why? What does this information offer the end user?

Can I somehow access these JAR files as ordinary java.io.File (or
rather java.util.zip.ZipFile)? With a normal application I would think
it wouldn't be too hard. But I'm not sure how to locate the file when
they have been loaded in Java Web Start. I suppose it'd be necessary
to look into the JWS cache or something?

It's better off looking into the reasons why you think
this strategy is required.
