jar files


I downloaded DEMViewer jar files from the VISAD site using Netscape
Navigator (shift-click to save file), but unfortunately all of them cannot 
be unpacked properly under my windows environment. The error information is 
as follows:
C:\visad\DEM>jar xf demv_src.jar
java.util.zip.ZipException: invalid entry size (expected 16896 but got 66

        at java.util.zip.ZipInputStream.readEnd(ZipInputStream.java:350)
        at java.util.zip.ZipInputStream.read(ZipInputStream.java:140)
        at sun.tools.jar.Main.extractFile(Main.java:676)
        at sun.tools.jar.Main.extract(Main.java:639)
        at sun.tools.jar.Main.run(Main.java:190)
        at sun.tools.jar.Main.main(Main.java:778)

This is also the problem when I try to unpack other jar files downloaded
from the VISAD website. Can someone out there let me know the right way to 
download or unpack these files?
