Base64.jar and zeus.jar

[Cai Qian <caiqian@gnome.org>]

Hi,
I am packaging a Java package now. I found in upstream source there are
some pre-supply .jar and .so files (because he works under windows).
Most of them exist in some Debian java libraries, so I can relink it.
However I don't know which packages contain Base64.jar and zeus.jar.
Does somebody know? 

If they don't, should I ask upstream author to supply these files source
code and include them? Another question is these .jar and .so files are
up to 3M, Is it right to delete them in original tarball before upload? 

Thanks,
