Well, the beginning of the URL was wrong because of the resource in the
virtualhost holder (the resource with the VirtualHostFrame). It is now
fixed with the VirtualHostResource which force the base URL of its
children to '/'.

Attached are the source and the .class of the new VirtualHostResource you
must use.

You will have to create your virtual holder again. The resource class will
be "org.w3c.jigsaw.resources.VirtualHostResource" instead of
"org.w3c.tools.resources.ContainerResource", then add the
VirtualHostFrame, as in the documentation
(http://www.w3.org/Jigsaw/Doc/User/virtual-hosting.html)
